CEO, <strong>EN</strong>GEL Holding<br />

In specific terms, this means two things: Keeping our production and<br />

development at <strong>EN</strong>GEL “in the region and for the region”, which in turn<br />

allows us to cater to the local conditions in your markets. Our many<br />

years of experience now enable us to implement local solutions with local<br />

development and manufacturing expertise.<br />

At the same time, we assist global players with managing the machine’s<br />

entire product life cycle based on global standards. Regardless of which<br />

and how many markets you have operations in, you can depend on a<br />

consistent level of quality – we guarantee global standards at local costs.<br />

<strong>EN</strong>GEL’s hub structure provides the ideal framework for this. Our hubs in<br />

the Americas, Europe and Asia regions are made up of largely independent<br />

units, each spanning sales, order processing, production and after<br />

sales. Where necessary and appropriate, global standards are applied in<br />

collaboration with head office in Austria.<br />

With this in mind, we are already looking forward to the trade shows we<br />

will be attending this spring with great anticipation: Chinaplas in Shanghai<br />

and NPE in Orlando. We will be showcasing new and exciting exhibits that<br />

cater to the relevant market needs. Our goal continues to be for <strong>EN</strong>GEL<br />

to act as a reliable partner for your high-quality and cost-effective injection<br />

moulding production – no matter where in the world you happen to be based.<br />

This issue of the magazine bears testament to that fact. On page 14,<br />

for instance, you can read about a tech-savvy contract manufacturer in<br />

Poland that is benefiting from what <strong>EN</strong>GEL has to offer – from extensive<br />

consulting expertise through integrated production units to staff training.<br />

We can give you everything from a single source, allowing you to lead<br />

the way in your market.<br />

St. Valentin large machine plant<br />

named 2023 factory of the year<br />

Panel impressed by digital transformation<br />

and consistency within sustainability strategy<br />

Awards for twostage<br />

process<br />

Efficient reuse of<br />

plastic waste<br />

Circular economy project manager<br />

Stefan Fehringer received the award.<br />

Martin Weger (back centre) with his leadership team at the St. Valentin plant.<br />

In a manufacturing competition organised<br />

by Fraunhofer Austria and Industriemagazin,<br />

<strong>EN</strong>GEL’s large machine plant at St.<br />

Valentin was declared Factory of the Year<br />

2023, confirming it as the best production<br />

facility in Austria. Along with the other<br />

<strong>EN</strong>GEL production plants, St. Valentin<br />

forms part of a global, high-performance<br />

network for complex and cutting-edge<br />

machine manufacturing.<br />

The accolade was awarded in part due to<br />

the carefully designed manufacturing process,<br />

in addition to the consistent sustainability<br />

strategy and pioneering role in digital<br />

transformation. “Having the right layouts<br />

and the right transport routes is particularly<br />

important when handling part weights of<br />

up to 150 tonnes, and implementation<br />

must be cleanly and carefully planned,”<br />

says plant manager Martin Weger. One<br />

project that lines up with this approach<br />

involved the expansion and redesign of<br />

the assembly line. The assembly principle,<br />

under which the clamping and injection<br />

sides of the machine are manufactured<br />

and assembled separately, is unparalleled<br />

in the area of special machine building.<br />

Recently realised optimisation measures<br />

have raised the plant’s output by 15%, with<br />

lead times cut by 65%.<br />

Having been named Product of the Year at<br />

the start of 2023, the two-stage process<br />

has now impressed in two more competitions.<br />

<strong>EN</strong>GEL took top honours for<br />

the process at the Recycling Machinery<br />

Innovation Award, which was handed out<br />

at the Plastics Recycling Show Europe. It<br />

also finished second in the regional innovation<br />

award for Upper Austria. Thanks to<br />

the two-stage process, it is possible to<br />

stably process plastic waste as flakes in<br />

injection moulding directly after grinding.<br />

With an entire process step, pelletising,<br />

being eliminated, costs, resources and<br />

energy can be saved – sustainability in<br />

both senses of the word!<br />

<strong>EN</strong>GEL leading on climate change globally<br />

Platinum status in 2023 Ecovadis rating<br />

Headquarters in Schwertberg – and many other locations – feature extensive PV systems.<br />

<strong>EN</strong>GEL continued to extend its lead in the<br />

global EcoVadis sustainability rankings in<br />

2023. Last autumn, the company was<br />

able to achieve platinum status and now<br />

ranks among the top 1% of the world’s<br />

most sustainable companies due to strong<br />

initiatives.<br />

“We are proud that our sustainability drive<br />

has once again been objectively confirmed,”<br />

says Stefan Engleder, CEO of<br />

the <strong>EN</strong>GEL Group. "It proves that we, as<br />

a company, are sticking to our principles,<br />

even in challenging times."<br />

EcoVadis is the world's largest provider<br />

of sustainability rankings. The rankings<br />

include data from more than 90,000<br />

evaluated companies and focus on the<br />

global supply chains in each case. The<br />

"We have been able to improve massively<br />

in the field of climate protection and are<br />

now one of the leaders," says Alexander<br />

Hell, Head of Sustainability Management<br />

at <strong>EN</strong>GEL, pointing out one detail. This is<br />

primarily due to the combination of science-based<br />

greenhouse gas reduction<br />

targets and the large numbers of climate<br />

action campaigns already implemented<br />

both at <strong>EN</strong>GEL locations and in the solutions<br />

portfolio. It was just this summer<br />

that <strong>EN</strong>GEL announced its commitment to<br />

the Science-Based Target Initiative (SBTI).<br />

This means that the company is 100%<br />

transparent in its sustainability efforts, and<br />

verifiably so based on scientific criteria.<br />

<strong>EN</strong>GEL Packaging Day <strong>2024</strong><br />

Less cost pressure and higher profitability for<br />

thin-wall injection moulders<br />

Manufacturers of thin-walled packaging solutions currently face major challenges, with increases in the<br />

price of energy and materials putting pressure on profit margins and making it harder to plan ahead. In<br />

addition, the constant growth in requirements with regard to recyclability is making production processes<br />

and products more complex. At Thin-Wall Packaging Day, <strong>EN</strong>GEL exhibited solutions for injection<br />

moulders to produce plastic packaging in a sustainable, profitable and viable manner for the future.<br />

On 8 February this year at Thin-Wall<br />

Packaging Day, <strong>EN</strong>GEL showcased<br />

as well as looking ahead to future<br />

developments in thin-wall injection<br />

moulding. The event combined<br />

presentations by well-known experts and in-depth<br />

insights based on specific best-practice case studies<br />

with interactive workshops on practical examples of<br />

applications, providing a comprehensive overview<br />

of <strong>EN</strong>GEL’s innovations for the packaging market.<br />

“In recent years, we have been hard at work to continue<br />

developing our injection moulding machines<br />

and solutions for thin-wall injection moulding,” says<br />

“A full toolkit” –<br />

Solutions for contract injection moulding manufacturers<br />

A large part of the plastics processing industry involves third parties being contracted to mass-produce<br />

the relevant products. <strong>EN</strong>GEL offers a whole range of products and services especially for the<br />

target group of contract and toll manufacturers. These meet the particular requirements at hand and<br />

provide the user with a whole host of benefits to increase their own competitiveness. We spoke to Patrick<br />

Grüner, who is responsible for injection moulding business development at <strong>EN</strong>GEL, about what<br />

opportunities exist and what <strong>EN</strong>GEL offers in addition to its range of injection moulding machines.<br />

When we talk about contract<br />

or toll manufacturers in the<br />

plastics processing sector, which<br />

particular challenges confront<br />

<strong>EN</strong>GEL for this target group?<br />

PATRICK GRÜNER: There are definitely<br />

three major challenges for the group<br />

of contract or toll manufacturers. The<br />

first to mention is the permanent cost<br />

pressure to make products as cheaply as possible.<br />

Another important aspect is flexibility and availability.<br />

For instance, this involves the ability for multiple products<br />

to be running on the same machine and for these to<br />

be available quickly. The third challenge, certainly at the<br />

moment, is the continuing shortage of skilled workers.<br />

What does <strong>EN</strong>GEL offer in<br />

terms of its injection moulding<br />

technology to respond to these<br />

particular challenges?<br />

GRÜNER: <strong>EN</strong>GEL responds to the<br />

particular challenges with a carefully<br />

coordinated range of machines to<br />

provide our contract manufacturing<br />

customers with the most cost-efficient<br />

8_<strong>EN</strong>GEL <strong>Injection</strong>-<strong>April</strong>-<strong>2024</strong>

in question are iQ weight control, iQ<br />

clamp control and iQ hold control. They<br />

very efficiently assist the user with minimising<br />

the machine’s downtime and<br />

getting back into the productive phase<br />

as quickly as possible, which for the<br />

contract manufacturer means the same<br />

thing as earning money.<br />

injection moulding machines possible.<br />

And naturally, that includes a wide<br />

variety of different lines, such as our<br />

Fast Track – our stock machine programme<br />

to meet our customers’ need<br />

for rapid availability. With our core<br />

expertise in machine technology, we<br />

offer flexible solutions both with our<br />

long-running favourite, the tie-barless<br />

machines, as well as with fully<br />

electric machines from our e-mac<br />

series, which are perfectly tailored to<br />

contract manufacturing. The support<br />

we offer does not end with our injection<br />

moulding machines. We also offer a<br />

wide range of solutions, digital products<br />

and automation options – a full<br />

toolkit for our customers’ challenges.<br />

Staying on the topic of challenges, productivity<br />

is a particular issue in volume production.<br />

Speed is of the essence. <strong>EN</strong>GEL has some<br />

different potential fixes to offer here.<br />

Could you describe these?<br />

GRÜNER: Productivity is the biggest challenge for contract<br />

manufacturers on a daily basis. Constant product<br />

changes and the mould set-up work this entails are part<br />

of everyday practice. One of the potential fixes we put a<br />

lot of stock in here, of course, is assistance from digital<br />

products. In this context, I would point to our set-up<br />

assistant and our iQ products. The iQ products are<br />

assistance products that really help to minimise set-up<br />

time and also speed up run-in, i.e. the time it takes<br />

to produce good parts on a machine. The products<br />

How might we picture this at<br />

<strong>EN</strong>GEL when you are looking<br />

for optimisation potential in the<br />

injection moulding process?<br />

Have the solutions all been<br />

developed in-house, or do we<br />

work hand in hand with the<br />

contract manufacturers and<br />

implement their suggestions –<br />

in line with the motto of “from<br />

real-world use, for real-world use”?<br />

GRÜNER: Yes, that is right. Aligning<br />

ourselves closely with real-world applications<br />

is essential, because the only<br />

way we can grow is together with our<br />

customers. Among other things, we<br />

offer in-house workshops where we<br />

work with the customer, for example,<br />

to simulate set-up processes on our<br />

machine to optimise it or demonstrate<br />

the iQ products in use. We also offer<br />

the same at our customers’ premises.<br />

So indeed, following the “from realworld<br />

use, for real-world use” motto.<br />

And many other products, such as iQ<br />

weight control and iQ hold control, are<br />

based on practical experience along<br />

with feedback from customers and the<br />

challenges they face on a daily basis.<br />

We are hearing more and more<br />

from contract manufacturers<br />

that there is a lack of skilled<br />

and qualified staff. But with the<br />

iQ family of digital assistance<br />

systems, it is possible to save<br />

on human resources. Would you<br />

agree with that statement?<br />

GRÜNER: That is right. In recent years,<br />

we have increasingly seen and heard<br />

that there is a major shortage of skilled<br />

labour in our industry. Our contract<br />

Patrick Grüner<br />

The aim is to<br />

make the entire<br />

process, from<br />

mould set-up<br />

to start of<br />

production, as<br />

simple as possible.<br />

Patrick Grüner<br />

10_<strong>EN</strong>GEL <strong>Injection</strong>-<strong>April</strong>-<strong>2024</strong>

and toll manufacturers are often very<br />

heavily affected by this trend due<br />

to the size of their companies. And<br />

needless to say, I see it as our duty<br />

to offer solutions on the machine<br />

side to counteract this trend. I know<br />

that we have definitely come a long<br />

way in making our machine’s set-up,<br />

run-in and operation as effortless<br />

and convenient as possible with our<br />

assistance systems. Anyone can set<br />

the machine up, anyone can run the<br />

machine in, anyone can operate the<br />

machine. The aim is to make the entire<br />

process, from mould set-up to start of<br />

production to supervision of production,<br />

as simple as possible to offset the<br />

lack of skilled staff. Also increasingly<br />

in demand are complete automation<br />

cells for injection moulding machines,<br />

again saving staffing resources. We<br />

already offer very small and simple<br />

automation solutions that are fully integrated<br />

into the control unit. This means<br />

I only need one person at the machine,<br />

and an expert is not necessarily needed<br />

to programme the automation. The<br />

incorporation of the control unit into<br />

the CC300 is fully integrated as part<br />

of the injection moulding process. No<br />

dedicated programming language or<br />

corresponding knowledge is required<br />

– an extensive array of details that add<br />

up and have significant effects.<br />

If a contract manufacturer has<br />

not yet had any experience<br />

with digital products in plastics<br />

processing, what would you<br />

recommend to them, Patrick?<br />

GRÜNER: My personal suggestion<br />

and what I recommend to everyone is<br />

the menu-guided mould set-up – i.e.<br />

our set-up assistant. It takes the form<br />

of a step-by-step guide in the control<br />

unit – similar to a cooking recipe. This<br />

helps to prevent errors and accelerate mould setup<br />

processes. It also thinks ahead to prepare the<br />

next mould for mounting. Everything is taken into<br />

account: the water, the couplings and much more.<br />

Operating errors are prevented and the speed of the<br />

set-up process is increased. And in terms of digital<br />

products, I definitely see the need for at least a trio<br />

of options from the entire iQ range. The first of these<br />

is iQ weight control. It helps the user when getting<br />

started with a new production process to minimise<br />

rejects and reduce their prevalence in the ongoing<br />

process due to material fluctuations, for example. It is<br />

also well known that contract manufacturers have to<br />

contend with considerations of recycling and material<br />

fluctuations. iQ weight control helps them to minimise<br />

rejects, which means higher productivity and higher<br />

earnings when all is said and done. The second iQ<br />

product is iQ clamp control. This helps the user to<br />

find the right clamping force without having to carry<br />

out lengthy investigations in the process. It becomes<br />

faster and also saves energy, because it does not<br />

always set the maximum clamping force. And a third<br />

option to consider, which I would be remiss not to<br />

mention, is iQ melt control. This smart assistant for<br />

nominal values also plays its part in the context of<br />

the skilled labour shortage and energy efficiency. It is<br />

brilliantly simple and convenient to set the plasticising<br />

time to an optimum level without being an expert<br />

on the machine. In fact, the machine itself finds the<br />

perfect plasticising time.<br />

But how do things look when<br />

it comes to machine running costs?<br />

GRÜNER: Essentially, it is not only the question of<br />

mould set-up that is important – there are also the<br />

running costs of the machines themselves. This is<br />

where we are focusing on energy efficiency and<br />

productivity. I briefly touched on the topic of energy<br />

efficiency in my last answer. For instance, iQ<br />

weight control helps to cut energy consumption. But<br />

the best tool we can use is temperature control or<br />

mould temperature control, which often accounts<br />

for up to 60% of the total energy consumed. With<br />

our intelligent solutions such as e-temp and e-flomo,<br />

we are significantly reducing energy costs on the<br />

machine and playing a major role in contract manufacturers<br />

being able to make cheaper products<br />

for the end customer while having more options<br />

at their disposal. I see productivity, on the other<br />

hand, as a classic matter for iQ weight control, which<br />

I use to substantially reduce the rejects rate, for<br />

example. And, of course, to increase productivity<br />

on the machine after I have already set up faster.<br />

Production runs in contract<br />

manufacturing on a set schedule.<br />

There is hardly any time for optimisation.<br />

<strong>EN</strong>GEL recognised this<br />

problem and created e-connect,<br />

a digital service that generates<br />

solutions promptly and in real<br />

time. Is this a must-have for<br />

contract manufacturers?<br />

GRÜNER: e-connect 24 offers the<br />

convenient option of immediate assistance<br />

in the event of problems. The<br />

machine operator is immediately put<br />

through to <strong>EN</strong>GEL and can report<br />

these issues to us (for example, in the<br />

event of machine downtime), which<br />

will then be followed by communication<br />

and solution finding. Based on<br />

the principle that “time is money”, it<br />

provides quick support in reaching<br />

solutions. e-connect helps to improve<br />

communication between <strong>EN</strong>GEL and<br />

the contract manufacturer and get<br />

the machine up and running again<br />

in short order.<br />

Last question, Patrick: Are<br />

the services and solutions<br />

mentioned suitable for contract<br />

manufacturing regardless of<br />

the industry? And does the<br />

company’s size play a role here?<br />

GRÜNER: For me, there is no difference<br />

between a small family business, an<br />

SME or a large corporate group. We<br />

offer our solutions to serve anyone and<br />

everyone. The focus for contract manufacturers<br />

is usually on small and medium-sized<br />

companies – stemming from<br />

tradition. This is because it tends to<br />

be smaller businesses that operate as<br />

contract manufacturers in this context.<br />

And our focus here is clearly on looking<br />

after and supporting these customers<br />

to keep developing our solutions with<br />

them and to grow<br />

<br />

together.<br />

The CC300 plus was<br />

developed on the basis of<br />

operator feedback for<br />

frequent mould set-up<br />

operations and frequent<br />

manual operation.<br />

The <strong>EN</strong>GEL CC300 plus control unit –<br />

a real plus in terms of ergonomics<br />

and haptic features<br />

The CC300 plus is a further development of <strong>EN</strong>GEL’s successful machine control unit. Supplementing<br />

the CC300 control unit family, it offers improved customisation and optimised ergonomics.<br />

The CC300 plus control unit is <strong>EN</strong>GEL’s response to<br />

user feedback and requirements. It does justice to<br />

what is increasingly becoming the norm in production<br />

unit operation: frequent mould set-up procedures and<br />

more manual tasks. It is for precisely these users that<br />

the new CC300 plus offers the necessary plus in<br />

terms of ergonomics and customisation. The threepart<br />

structure with a double swivel mechanism and<br />

the individually assignable pushbutton panel are the<br />

striking differences from the CC300.<br />

More movement: make three out of one<br />

The ergonomic plus-point is the <strong>EN</strong>GEL CC300 plus’<br />

three-part structure made up of a trio of panels – the<br />

switch-on, visualisation and pushbutton panels. The<br />

switch-on panel has the normal functions for user<br />

login, emergency stop and the swivel mechanism. As<br />

an option, mechanical switches can be housed for<br />

safety-relevant functions, as can individual extensions.<br />

User login is just like on the CC300, relying on RFID<br />

with the typical EUROMAP65 standard. Optionally,<br />

the CC300 plus already supports the new MIFAREbased<br />

login system, which gives administrators the<br />

ability to set up targeted authorisations<br />

for operators. Like the current CC300,<br />

the visualisation panel features a 21.5“<br />

touch screen. This central panel is<br />

intended for navigation, process settings<br />

and general displays. The newly-developed<br />

pushbutton panel is the<br />

core of the new CC300 plus.<br />

New pushbutton panel for<br />

haptic features, visual appeal<br />

and customisation<br />

The striking eight pairs of pushbuttons<br />

on the CC300 plus provide haptic key<br />

feedback, giving the user a great feeling<br />

for safety and transparent control<br />

of an <strong>EN</strong>GEL production cell. Like<br />

with the CC300, all the plus variant’s<br />

pushbuttons can be assigned individually<br />

and in a clear-cut way. Individual<br />

functions are quickly accessible via<br />

touch controls – whether via e-move<br />

or pushbutton pairs. In addition,<br />

several different settings can now<br />

be defined for the pushbutton panel<br />

in order (for example, to be able to<br />

The <strong>EN</strong>GEL CC300 plus control unit with optimised<br />

ergonomics and improved customisation options.<br />

using keys. The optimum working<br />

position is stored on the control unit<br />

as a function of the user. If the control<br />

unit is not actuated for a certain period<br />

of time or if the machine operator logs<br />

off, it returns to the starting position<br />

and – like the CC300 – melds with<br />

the injection moulding machine. This<br />

function also reliably avoids collisions<br />

with forklifts or the increasingly common<br />

autonomous vehicles used in<br />

production. After the user logs on,<br />

the panels move back to the optimum<br />

position as set by the operator.<br />

More transparency:<br />

the e-move sequence<br />

Visual displays make machine operation<br />

even easier: colours and symbols<br />

show whether a function is in use<br />

in the current sequence, indicating<br />

whether control is or is not possible<br />

at the current point in time of the<br />

process. The end position of the controlled<br />

movement is also indicated.<br />

As soon as a key is pressed, a bar<br />

display for the "actual travel value"<br />

appears and the operator can follow<br />

the movement more-or-less live.<br />

e-move is the special feature of the<br />

<strong>EN</strong>GEL CC300 control unit family.<br />

The control wheel makes it particularly<br />

easy to manually cycle through<br />

sequences on the production cell.<br />

What is new with the CC300 plus is<br />

the e-move sequence, which is visible<br />

on the display and shows the stored<br />

functions in the order of actuation.<br />

Again, this function sequence can be<br />

edited individually adapted. e-move<br />

is also wear and maintenance free<br />

thanks to a new control technology.<br />

Manual operation made easy<br />

Currently more than 40,000 <strong>EN</strong>GEL production cells<br />

are equipped with the CC300. Every one of them<br />

can be upgraded to the CC300 plus if needed. In<br />

the future, users will be able to choose between the<br />

two control units as the CC300 plus is also available<br />

for all machine types.<br />

The <strong>EN</strong>GEL CC300 plus is an excellent choice wherever<br />

everyday operations often require manual operation.<br />

This can be necessary, for example, due to frequent<br />

mould set-up for small batches, which is typical in<br />

contract manufacturing at times, or in the automotive<br />

industry. The <strong>EN</strong>GEL CC300 plus is also well suited<br />

for production cells used in technology centres as flexible<br />

development partners. And sometimes the most<br />

important reason for the decision may simply be that<br />

the machine operator<br />

wants a control unit that<br />

makes their work easier<br />

by going the extra<br />

mile in terms of smart<br />

haptic features and<br />

customisation. <br />

Technologies for the future<br />

As opportunities grow, so do requirements – and sales revenues. This is a strategy that really works<br />

for SPLAST. The company's own products – cleaning trolleys for professional use – are a kind of<br />

research laboratory for the plastics processor. This is where the latest technologies are tested and<br />

enhanced in order to offer contract manufacturing customers particularly high-quality and efficient<br />

system solutions. <strong>Injection</strong> moulding machine manufacturing partner <strong>EN</strong>GEL provides support in the<br />

form of engineering know-how, system solutions and training.<br />

Green is the predominant colour on<br />

the one hundred metre-long production<br />

floor at SPLAST’s headquarters<br />

in Krosno, southern Poland. <strong>EN</strong>GEL<br />

Green to be precise. “<strong>EN</strong>GEL is our<br />

go-to supplier for injection moulding<br />

machines,“ emphasises CEO Marek<br />

Sanocki, whose company has seen<br />

substantial business growth. 700<br />

employees at four production plants<br />

– three in Poland and one in Hungary<br />

– generated sales revenues of 78<br />

million euros in the fiscal year 2022.<br />

This makes SPLAST one of the largest<br />

plastics processors in Poland.<br />

SPLAST's customers come from the<br />

automotive, electronics, household,<br />

cosmetics and furniture industries.<br />

Marek Sanocki is proud to point out<br />

the most recently delivered production<br />

cell. Two <strong>EN</strong>GEL duo injection<br />

We are development<br />

partners and co-designers<br />

Dr. Monika Stacel, Head of R&D, SPLAST<br />

articulated robots, two <strong>EN</strong>GEL viper linear robots, an<br />

IR oven and a polyurethane line. Both of the machines<br />

are impressive. Any number of technology packages,<br />

including packages for multi-component and structural<br />

foam moulding, in-mould decoration and in-mould<br />

painting, and composite processing. And beyond this,<br />

numerous smart assistance systems from the <strong>EN</strong>GEL<br />

inject 4.0 range. “We are development partners and<br />

co-designers for our customers and contribute many<br />

ideas for series production ourselves,“ says Dr. Monika<br />

Stącel, Head of Research and Development at<br />

SPLAST. “This is what makes it so important for us to<br />

keep pushing forward. Expanding our own know-how<br />

and conducting our own research.“<br />

In this respect, the company benefits<br />

from close cooperation with universities.<br />

Besides her work at SPLAST,<br />

Dr. Stącel is a professor at Uczelnia<br />

Państwowa w Sanoku University in<br />

Sanok, one hour's drive southeast of<br />

Krosno. Beyond this, there is also a<br />

partnership with the Technical University<br />

of Chemnitz in Germany.<br />

Maximum flexibility<br />

reliably implemented<br />

The new production cell is also<br />

remarkable on account of the difficult<br />

circumstances during project planning.<br />

The first project meeting between<br />

SPLAST and <strong>EN</strong>GEL took place in<br />

spring 2020. One week later, Austria<br />

and Poland entered their first Covid<br />

lockdowns. Meetings continued using<br />

remote technologies, and despite the<br />

massive complexity of the production<br />

cell, <strong>EN</strong>GEL was able to deliver just ten<br />

months after the order was placed.<br />

“The decisive factor in favour of <strong>EN</strong>GEL<br />

was their technological expertise,“ as<br />

14_<strong>EN</strong>GEL <strong>Injection</strong>-<strong>April</strong>-<strong>2024</strong>

Dr. Henryk Majcherczyk, the Technical<br />

Director of SPLAST explains. “We can<br />

group many different technologies on<br />

a single injection moulding machine<br />

and combine their use.“ “We also benefit<br />

from the fact that <strong>EN</strong>GEL supplies<br />

all of the system components from a<br />

single source as integrated production<br />

cells,“ as Production Manager Przemysław<br />

Dylewski adds. “Right down<br />

to training our employees, because<br />

that is our only way to make sure we<br />

leverage all the opportunities the production<br />

cell offers.“<br />

One of the key features of holistic<br />

system solutions by <strong>EN</strong>GEL is that<br />

all of the units, such as the injection<br />

moulding machine, the robot and the<br />

IR oven, use a shared database and<br />

communicate with one another. This<br />

reduces the risk of input errors and<br />

saves time because the robot and<br />

machine can precisely coordinate<br />

their motion sequences.<br />

“The biggest challenge for us was<br />

to design the production cell so that<br />

it could be used in a totally flexible<br />

way while complying with all safety<br />

standards,“ reports Thomas Auböck,<br />

Automotive Sales Manager at <strong>EN</strong>GEL headquarters in<br />

Austria. “Production cells with this kind of complexity<br />

are usually tailor-made for a specific product. But we<br />

have a special case here where many different moulds<br />

are set up and the two duo machines are used in<br />

both interlinked applications and independently of<br />

one another.“ A special feature of the <strong>EN</strong>GEL easix<br />

articulated robots comes into play to make sure that<br />

this works reliably. The prohibited areas can be freely<br />

defined and the robot workspaces safely monitored.<br />

This means that the two injection moulding machines<br />

do not require separate safety guarding, even if they<br />

are working simultaneously with moulds which are<br />

independent of one another.<br />

“The team at SPLAST is very creative when it comes<br />

to combining different technologies. For example, they<br />

were the first to combine the <strong>EN</strong>GEL organomelt and<br />

DecoJect® technologies in a single application – and<br />

they have done so successfully,“ says Adam Marciniak,<br />

who works as a Sales Manager at <strong>EN</strong>GEL Polska.<br />

The main target group is the automotive industry,<br />

which faces the challenge of efficiently combining<br />

lightweight construction with surfaces which offer<br />

a premium appeal paired with functionality.<br />

Efficient lightweight construction<br />

in an integrated process<br />

In the <strong>EN</strong>GEL organomelt process,<br />

thermoplastic fibre composite prepregs<br />

– for example, thermoplastic<br />

sheets – are formed and functionalised<br />

in a single integrated step. For<br />

example, reinforcing ribs or assembly<br />

elements are moulded immediately in<br />

the same mould after thermoforming<br />

using a thermoplastic from the same<br />

matrix material group as the thermoplastic<br />

sheet. This not only enables<br />

a highly efficient, integrated and fully<br />

automated production process, but<br />

also contributes to the circular economy.<br />

The consistent thermoplastic<br />

mono-material approach facilitates<br />

subsequent recycling of the parts.<br />

Parts produced using organomelt<br />

have recently been added to SPLAST's<br />

AquaSplast, ComfortSplast and AssepticoSplast<br />

brand cleaning trolleys.<br />

Depending on the location of use,<br />

whether office building, hotel or hospital,<br />

the trolleys are equipped with<br />

cleaning water containers, laundry<br />

containers, waste sorting systems<br />

and other modules, which means<br />

Picture: SPLAST<br />

All of the <strong>EN</strong>GEL injection moulding<br />

machines at SPLAST are equipped<br />

with smart assistance systems.<br />

Employees are trained by <strong>EN</strong>GEL,<br />

empowering them to leverage the full<br />

potential offered by the machines.<br />

<strong>EN</strong>GEL is the predominant injection moulding machine brand at the SPLAST plants. There are currently 23<br />

injection moulding machines on the list of machinery at the Krosno location.<br />

<strong>EN</strong>GEL <strong>Injection</strong>-<strong>April</strong>-<strong>2024</strong>_15

that they are fairly large. Lightweight<br />

construction technologies contribute<br />

significantly towards making the<br />

trolleys easy to push and steer on a<br />

wide variety of floor coverings despite<br />

having a very rugged design.<br />

<strong>EN</strong>GEL organomelt technology has<br />

helped to reduce the weight of the<br />

cleaning trolleys' floor plates from 4.5<br />

to 1.3 kilograms. Instead of the previous<br />

4 mm, the new plates are only 0.5<br />

mm thick, but they have become even<br />

more stable at the same time. Another<br />

advantage, and one which impresses<br />

customers in the automotive industry<br />

in particular, is that polypropylene,<br />

which is more cost-effective than the<br />

legacy high-performance thermoplastics,<br />

can be used as the basic material<br />

in these applications. To manufacture<br />

the base plates, thermoplastic sheets<br />

with a PP matrix are moulded on the<br />

duo 500 injection moulding machine<br />

and overmoulded with glass-fibre-reinforced<br />

PP.<br />

To make the thermoplastic sheets<br />

malleable, they are heated in the IR<br />

oven immediately before being placed<br />

as inserts in the mould. To allow this<br />

to happen, the IR oven is set up very<br />

close to the clamping unit of the duo<br />

machine so that the easix robot can<br />

reach the mould cavity via the shortest<br />

route from the IR oven. “This is why<br />

we planned for a mobile IR oven from<br />

the outset. We can move it back and<br />

forth between the two duo machines<br />

and process thermoplastic sheets on<br />

both machines as a consequence.“<br />

Cost-efficiency for premium,<br />

visible components<br />

Decoject is an in-mould decoration<br />

(IMD) process which helps to achieve<br />

the desired surface properties using<br />

a film that is fed to the mould reelto-reel.<br />

This enables special surface<br />

structures or even a soft-touch tactile<br />

experience. SPLAST uses Decoject<br />

technology to manufacture the handles<br />

for the cleaning trolleys and ensure a good grip.<br />

Again, the basic material is PP; with a recycled material<br />

content of 20 percent in this case. The handles are<br />

located on a frame component which neatly seals off<br />

the larger cleaning trolleys at the top. SPLAST relies<br />

on another innovative <strong>EN</strong>GEL technology for these<br />

two-component parts, which are produced on the<br />

duo combi M injection moulding machine: clearmelt or<br />

in-mould painting, as the SPLAST engineers refer to it.<br />

The integrated clearmelt process involves first<br />

injecting a basic thermoplastic carrier, the surface<br />

of which is then immediately enhanced with a layer<br />

of polyurethane in the same mould. The polyurethane<br />

ensures both a high gloss level and excellent scratch<br />

resistance. Thanks to the combi M design with a horizontally<br />

rotating indexing table, the two process steps<br />

take place in parallel on the duo injection moulding<br />

machine.<br />

“Things will start to get really exciting when we combine<br />

clearmelt with an IMD process,“ says Monika<br />

Stącel, outlining the roadmap for projects which are<br />

the subject of talks with customers from the automotive<br />

industry, but also other sectors – for example<br />

domestic appliances. Electronic functionalities and<br />

sensors can be efficiently integrated using a film,<br />

The decisive factor in favour<br />

of <strong>EN</strong>GEL was their<br />

technological expertise.<br />

Dr. Henryk Majcherczyk,<br />

Technical Director, SPLAST<br />

and they are safely protected under the polyurethane<br />

layer in the finished part, even in harsh environments.<br />

Recycled material from in-house production<br />

Weighing in at 12,550 tonnes per year, polypropylene<br />

accounts for the lion's share of raw material processed<br />

at the SPlast Group's production plants. ABS, polyamide<br />

and polycarbonate each account for around<br />

6,000 tonnes. And there are smaller volumes of other<br />

materials, such as TPE.<br />

Across the entire product range, SPLAST has set<br />

itself the goal of successively increasing the share<br />

of recycled material. Individual products are already<br />

made from 100 percent recycled material today, while<br />

the share is currently 20 percent in other products,<br />

and SPlast is looking closely at how to increase this.<br />

Innovative processing technologies play a central<br />

role here, as the Decoject example shows. Another<br />

approach is to embed the recycled material in a shell of<br />

virgin material. The coinjection and skinmelt technologies<br />

make this possible. "There have already been<br />

tests on this at the <strong>EN</strong>GEL technology<br />

centre in Austria," Sanocki reports. The<br />

SPLAST managers have also already<br />

set their sights on the new two-stage<br />

process as a particularly energy-efficient<br />

method of processing plastic<br />

flakes directly.<br />

One special feature of SPLAST in<br />

Krosno is that some of the regrind<br />

used here comes from the company's<br />

in-house treatment plant. Located<br />

directly adjacent to the injection<br />

moulding shop there is a complete<br />

recycling line, including all processing<br />

steps from shredding of plastic<br />

waste to compounding, extruding and<br />

repelletising. “My baby“, says Monika<br />

Stącel proudly. She set up the line<br />

and is responsible for the ongoing<br />

development of recycling capacities at<br />

the location. “We rely on our recycling<br />

plant to be able to genuinely keep control<br />

over the properties of the recycled<br />

materials,“ says Stącel. “In most cases,<br />

the MFI of bought-in recycled material<br />

is higher than that of corresponding<br />

virgin material. But we can set the<br />

value for our own production very<br />

accurately.“<br />

The energy requirement for each kilogram<br />

of pellets processed is dropping<br />

continuously. The ecodrive servohydraulics<br />

of the <strong>EN</strong>GEL injection<br />

moulding machines contribute to<br />

this, as do digital smart assistance<br />

systems by ensuring uniform cycles<br />

and constant temperature control<br />

conditions. The company's commitment<br />

to climate protection is also<br />

<br />

visible to the outside world.<br />

High-performance packaging:<br />

Mould and machine working symbiotically<br />

The introduction and expansion of new business areas has created new challenges for German<br />

mould-makers Erwes Reifenberg GmbH & Co. KG. This has included an expansion in the company’s<br />

in-house technology centre for development, testing, and trials of high-performance moulds. <strong>EN</strong>GEL’s<br />

e-speed 550, a high-performance injection moulding machine, was recently installed. “In the North<br />

American market in particular, the trend is towards larger moulds, so we have been able to reposition<br />

ourselves strategically by making this investment in a new injection moulding machine following our<br />

positive experiences with <strong>EN</strong>GEL,” explains CEO John Erwes.<br />

The demands placed on modern mould-makers are<br />

becoming increasingly complex. Mould-makers Erwes<br />

Reifenberg GmbH & Co. KG also have to contend with<br />

this trend in the market. “We had two major projects<br />

in 2020, which we completed successfully but which<br />

pushed us to the limits of what was possible with the<br />

existing injection moulding machine,” recalls Erwes,<br />

the second-generation chief executive of the family<br />

business. The company had previously<br />

been using an <strong>EN</strong>GEL e-motion 110<br />

T. However, to meet all the technical<br />

challenges with regard to high-performance<br />

moulds for the packaging<br />

sector, machine performance across<br />

a diverse series of dimensions is just<br />

as important. “When it comes to new<br />

investments, we listen to our staff, who<br />

have confirmed to us that they have<br />

had excellent experiences with the<br />

<strong>EN</strong>GEL machine – especially when<br />

using the control unit,” John Erwes<br />

confirms. Sales Manager Jan Hock<br />

adds: “This machine continues to<br />

manufacture with the highest precision<br />

and reliability, even though it is in use<br />

every day – truly every day.”<br />

Moulds with low cycle times and<br />

extensive functions for the item<br />

Erwes Reifenberg builds moulds that<br />

work with cycle times of around 2.5<br />

seconds. “From a strategic standpoint,”<br />

says Erwes, “we wanted to<br />

position ourselves more flexibly<br />

with a new machine.” The technical<br />

requirements were agreed in advance<br />

together with Stefan Witt, packaging<br />

specialist and sales manager for packaging<br />

machines at <strong>EN</strong>GEL’s Hagen<br />

location. “Originally, the initial discussions<br />

always focused on a machine<br />

with a lower clamping force, as the<br />

customer’s initial focus was on the<br />

We guarantee certain cycle<br />

times and functionality<br />

to our customer.<br />

Jan Hock, Sales Manager,<br />

Erwes Reifenberg GmbH & Co. KG<br />

production of caps and closures,” Witt recalls. But<br />

much more was required – in particular flexibility: with<br />

regard to both the clamping force to be selected<br />

and the injection moulding machine’s performance.<br />

“In the end, we talked about considering thin-walled<br />

products.” Ultimately, after extensive consultation, the<br />

decision was made in favour of an <strong>EN</strong>GEL e-speed<br />

offering 550 tonnes of a clamping force. The basic<br />

set-up already meets the requirements through the<br />

use of a wide range of moulds. “This model series is<br />

specially designed for high-performance applications<br />

in the packaging industry,” Witt says, outlining the<br />

applications covered by this machine variant.<br />

Hybrid machine with<br />

low energy consumption<br />

The <strong>EN</strong>GEL e-speed 550 has a<br />

high-performance electric clamping<br />

unit, which is the key ingredient in<br />

the electric drive systems’ low energy<br />

consumption. The injection moulding<br />

machine is also equipped with a servo-electric<br />

ejector. The pre-set tie-bar<br />

spacing of 1,050 x 1,050mm enables<br />

Erwes Reifenberg to set up flexible<br />

mould sizes on the machine and also<br />

provides a completely oil-free mould<br />

installation space. An encapsulated<br />

toggle lever prevents the packaging<br />

products from being contaminated with<br />

oil. Another of the machine’s attributes<br />

is that all machine movements are<br />

always carried out in parallel operation.<br />

<strong>EN</strong>GEL <strong>Injection</strong>-<strong>April</strong>-<strong>2024</strong>_19

When it comes to<br />

investments, we listen to<br />

our staff, who confirm<br />

having had excellent<br />

experiences with <strong>EN</strong>GEL.<br />

John Erwes, CEO, Erwes Reifenberg GmbH & Co. KG<br />

The equipment the injection moulding machine<br />

comes with now offers Erwes Reifenberg the flexibility<br />

it had desired. “We can now fulfil all of our<br />

customers’ test requirements here,” explains Jan<br />

Hock. This injection moulding machine is designed<br />

for the moulds produced in Finnentrop, Germany,<br />

for consumer packaging, beauty care products and<br />

pharmaceuticals, as well as for thin-walled products,<br />

which have recently been in increasing demand at<br />

Erwes Reifenberg. “At the same time, of course, we<br />

save valuable time by using two machines, enabling<br />

fewer set-up processes,” says Hock, describing a<br />

practical advantage. This should not be underestimated,<br />

he continues, “because quick mould set-ups<br />

are a thing of the past due to overloading of individual<br />

machines.” For smaller mould dimensions, the <strong>EN</strong>GEL<br />

e-motion 110 T continues to be used to lighten the<br />

550-tonne machine’s workload. “By being able to<br />

switch to another machine, we gain time to make fine<br />

adjustments to the mould.”<br />

“We make moulds with a high number of cavities and<br />

extensive functions on the mould, and the customer<br />

requires us to test these functionalities in house and<br />

in advance,” John Erwes explains. This is in line with<br />

the company’s own standards, he explains, as Erwes<br />

Reifenberg’s philosophy has always been to test<br />

moulds out in house. “We guarantee<br />

certain cycle times and functionality<br />

to our customer,” Hock notes, “which<br />

is why the machine performance has<br />

to reflect these challenges in practice.”<br />

Witt delivers the figure to back this up:<br />

The e-speed generates cycle times<br />

of less than two seconds during the<br />

process.<br />

Partnership between mouldmaker<br />

and machine manufacturer<br />

Michael Wiesinger, Head of Medical<br />

and Packaging Sales Europe Central<br />

at <strong>EN</strong>GEL Austria, emphasises the<br />

importance of keeping mould and<br />

machine perfectly coordinated: “Without<br />

the right machine performance,<br />

the mould cannot produce quality<br />

products, just as an injection moulding<br />

machine cannot produce the perfect<br />

result without the right mould.” <strong>EN</strong>GEL’s<br />

experience of working with Erwes<br />

Reifenberg has been highly positive,<br />

he confirms: “To obtain complex and<br />

demanding projects in the future, a<br />

high-performance machine that supports<br />

the mould-makers in their applications<br />

is essential.” Witt summarises:<br />

“The mould and machine have to be<br />

working on the same level.”<br />

“Partnership” is the key word for John<br />

Erwes in this regard. For Erwes Reifenberg’s<br />

CEO, a good relationship<br />

between mould-maker and machine<br />

manufacturer is the only way for a<br />

business to successfully assert itself in<br />

the market and grow. The company is<br />

increasingly developing into a service<br />

partner in the mould-making space.<br />

“This includes fixing up third-party<br />

moulds, for which we have set up<br />

our own department.” By setting<br />

up the e-speed 550 in Finnentrop,<br />

<strong>EN</strong>GEL will be able to deliver its own<br />

customer projects in partnership with<br />

the family-owned company thanks<br />

to its proximity to the Hagen service<br />

location. “A win-win situation,” says<br />

Michael Wiesinger with confidence. <br />

The mould and machine<br />

have to be working<br />

moulding machines changed? The authentig MES software from <strong>EN</strong>GEL has been providing the right<br />

answers since 2019 at Austrian plastics processors Kromberg & Schubert Austria GmbH & Co. KG<br />

(Kroschu for short).<br />

A total of 34 injection moulding machines<br />

ranging from 15 to 700 tonnes of clamping<br />

force produce around 300 million plastic<br />

parts every year.<br />

Before: Where paperwork once reigned, the aim is now to make production completely paperless in the near future.<br />

A series of blue document folders,<br />

filled to the brim with handwritten<br />

notes and printed Excel-based planning<br />

documents, are used on every<br />

single project at Kroschu. These folders<br />

contain the complete mould history.<br />

“From the first mould set-up to the first<br />

good part produced,” explains Robert<br />

Jautz. Every process step is documented<br />

- for over 600 active moulds kept<br />

and maintained in the Austrian town<br />

of Oberpullendorf alone. For production,<br />

which currently encompasses<br />

34 injection moulding machines<br />

with 15 to 700 tonnes in clamping<br />

force, this is an immense burden.<br />

A comprehensive solution was<br />

needed to replace the time-consuming<br />

documentation at Kroschu.<br />

The company first came into contact<br />

with the authentig MES solution at<br />

a trade show. The software-based<br />

application was then introduced in<br />

2019, when manual data maintenance<br />

at Kroschu was phased out by consistent use of<br />

authentig. Step by step, manual process tracking<br />

was transformed into a smart factory set-up.<br />

<strong>EN</strong>GEL authentig: Modular MES solution<br />

for the plastics industry<br />

The authentig MES software is a modular solution that<br />

has been specially developed for the plastics industry.<br />

The software’s focus is on creating transparent<br />

production, generating data-based knowledge about<br />

the company’s internal processes that was previously<br />

unavailable or only available in part. By interconnecting<br />

all its injection moulding machines, Kroschu<br />

is now able to uniformly record all their operating<br />

and production data. The machine operator uses<br />

the seven monitors installed on the production floor<br />

to interact with the system, where he is shown the<br />

order start and stop times as well as the documents<br />

required for the production project. A<br />

monitor located in the middle of the<br />

production facility also clearly displays<br />

the injection moulding machines’ current<br />

status. “The web terminal has<br />

met with a very good reception from<br />

both me and my colleagues,” says a<br />

pleased Robert Jautz.<br />

In addition to the monitoring module,<br />

the maintenance module is also of<br />

particular importance at Kroschu.<br />

When a project is created, all the content<br />

is available for the mould-making<br />

process at the same time. This guarantees<br />

a high quality standard, high<br />

mould availability and an immediate<br />

response to questions from the auditor.<br />

Thanks to defined maintenance<br />

plans that are stored in the system,<br />

machine downtimes due to unplanned<br />

mould maintenance work are practically<br />

a thing of the past. Thanks to<br />

the relevant production hours being<br />

Strong collaboration (left to right): Robert Jautz from Kroschu,<br />

Alexander Ebner and David Kupfer from <strong>EN</strong>GEL, in front of one<br />

of the seven monitors in the production facility.<br />

recorded, these maintenance intervals<br />

can be monitored in a fully automatic<br />

process and announced in good time.<br />

The process steps are always entered<br />

in authentig and the items to be produced<br />

are assigned numbers for<br />

identification. “When customers place<br />

orders, the data from production is<br />

automatically sent to authentig,” says<br />

Jautz, offering his appreciation for the<br />

software’s intuitive operation. <strong>EN</strong>GEL’s<br />

machine operators have been trained<br />

to identify errors in production. Additional<br />

monitoring is carried out by staff<br />

in the quality assurance team – a unit<br />

that is present on all production shifts.<br />

Since Kroschu products have gone<br />

global, there is a possibility that a<br />

complaint will only arise a few weeks<br />

after the batch of items has been completed.<br />

“authentig is a huge help for us<br />

when processing complaints,” Jautz<br />

confirms. Using the existing data set,<br />

it is possible to seamlessly trace back<br />

how the deviation from the desired<br />

condition occurred, whether due to<br />

changes in the machine parameters or<br />

faulty material. David Kupfer stresses<br />

that the process values are also monitored<br />

in real time via the quality process<br />

module; warnings in the monitoring<br />

system or push notifications “indicate<br />

that machine parameters or the cycle<br />

time have changed, for instance.” In<br />

this context, Alexander Ebner, System<br />

Engineer/Consultant at <strong>EN</strong>GEL, refers to the specially<br />

developed app, which can be used to conveniently<br />

monitor the relevant processes 24/7. Kroschu can<br />

usually take immediate action if the process data<br />

departs from the pre-defined tolerance ranges, as<br />

technical staff are always available every production<br />

day to remedy errors.<br />

9% increase in OEE:<br />

Kroschu delivering positive results<br />

Robert Jautz takes a positive conclusion from four<br />

years of using <strong>EN</strong>GEL’s authentig software. Overall<br />

equipment effectiveness (OEE) has risen significantly<br />

in recent years. Alexander Ebner explains that three<br />

key performance indicators are<br />

multiplied to reach this figure:<br />

quality, performance and availability.<br />

“By measuring and monitoring<br />

the KPIs on a daily basis,<br />

we have been able to optimise<br />

our outcomes. In three years,<br />

the figure has gone up by 9%.”<br />

Jautz emphasises that this has<br />

had positive cost effects. <br />

When speed matters,<br />

space and time are factors<br />

For traditional contract manufacturers, time windows have shrunk. Customers want finished products<br />

quicker all the time – and generally in small quantities. For Wicro Plastics, a plastics specialist based<br />

in the little Dutch town of Kessel, this presents new challenges every day – challenges that call for<br />

paced production and reliable partners who can offer fast response times. With this in mind, Wicro<br />

turned to <strong>EN</strong>GEL's range of Fast Track machines, which delivers time and costs benefits that add up<br />

to a competitive advantage.<br />

Walking around the spacious production<br />

floor of Wicro Plastics, you get a<br />

sense of organised activity. 44 injection<br />

moulding machines doing what<br />

they do, operated by trained personnel<br />

working in shifts. There is no hint of<br />

haste or panic among the Wicronese,<br />

as the 120 or so staff members are<br />

proudly known. The term started out<br />

as a joke, but has since evolved into a<br />

major feature of the brand, even internationally.<br />

As contract manufacturers,<br />

the Wicronese have to perform a delicate<br />

balancing act every day. “Customers<br />

want their products faster<br />

and faster all the time, and in small<br />

quantities,” confirms Marcel Kessels,<br />

Production Manager at Wicro. “They<br />

expect us to have everything in stock<br />

and start with injection moulding<br />

production the day after they place<br />

an order.”<br />

More than 20 mould changes –<br />

every day<br />

The upshot of a high degree of diversity<br />

in production, characterised by<br />

numerous products in a lot of different<br />

colours and designs, is that only small<br />

quantities of a component, i.e. up to<br />

2,000 items, are produced in a typical<br />

day. “We have 44 different products<br />

on the machines, which means more<br />

than 20 mould changes every day,”<br />

We foresee a<br />

trend away from<br />

PA and towards PP.<br />

Evelien Fassotte, Wicro Plastics<br />

emphasises Kessels. A very high vertical range of<br />

manufacture means that the company produces<br />

everything from parts for children’s furniture (like pushchairs<br />

and high chairs) to toolboxes of all types, washing<br />

machine components and coils for 3D printers, to<br />

give just a few examples. Evelien Fassotte, Director of<br />

Wicro Plastics, cites an example to illustrate day-today<br />

business. She describes an enquiry from a new<br />

client that relocated all of its existing moulds to Wicro.<br />

Normally, a commissioned project like that would take<br />

eight months; in this case, the time window was cut<br />

down to six weeks – six weeks at most to supply a<br />

machine that would meet the production requirements<br />

defined by the customer. “We gave René a call to ask<br />

if he could supply a suitable Fast Track machine,”<br />

recalls Evelien Fassotte. René de Looff being the<br />

responsible account manager for <strong>EN</strong>GEL Benelux: “It<br />

was all very casual, but we managed it – in six weeks,<br />

the machine was producing to the required qualities.”<br />

Large selection of Fast Track machines<br />

<strong>EN</strong>GEL has a wide range of Fast Track machines<br />

that can be supplied and put into operation at short<br />

notice. Production using these machines is carried<br />

out on an ‘express loop’ in the <strong>EN</strong>GEL factories,<br />

which means fast production and fast deliveries. To<br />

a predefined and limited extent, options are possible<br />

on Fast Track machines to ensure on-time deliveries<br />

to clients. “The Fast Track programme enables us to<br />

respond to short-notice customer demands via three<br />

different series and a range of clamping<br />

forces,” explains René de Looff. In<br />

the case of Wicro, those responsible<br />

got together to consider what type<br />

of machine would be most suitable<br />

for meeting the specific production<br />

requirements. Then they placed an<br />

order for an <strong>EN</strong>GEL duo 1150. “By<br />

the way, this was the third Fast Track<br />

machine delivered to Wicro recently,”<br />

says de Looff. At present, the machine<br />

is being used to manufacture a toolbox<br />

using <strong>EN</strong>GEL foilmelt IMD (in-mould<br />

decoration) technology. “We reached<br />

a decision to make this investment in<br />

less than two days. Production was<br />

up and running in exactly six weeks,”<br />

reports Kessels. “Now we can also<br />

offer our clients Fast Track deliveries,”<br />

adds Fassotte.<br />

Evelien Fassotte does not perceive<br />

any major risk in purchasing Fast Track<br />

machines. “Yes, machine capacities<br />

have to be utilised. On this order, for<br />

example, we hit capacity utilisation of<br />

50 percent straight away. Of course,<br />

we always have the option of adapting<br />

the machines to other tasks.”<br />

Space: Another factor in<br />

short-notice supply capability<br />

Alongside the time factor, space is<br />

another consideration when it comes<br />

to responding to customer requirements<br />

promptly and flexibly. “Thanks<br />

to its high clamping force, the <strong>EN</strong>GEL<br />

duo 1150 produces correspondingly<br />

large parts. If we need to manage customer<br />

stocks here on site, we need an<br />

appropriately large storage capacity.<br />

The challenges in terms of our supply<br />

capability increase along with the size<br />

of the machines,” explains Marcel Kessels.<br />

With this in mind, Wicro set up a<br />

warehouse to hold a ‘safety stockpile’.<br />

The logistical challenge intensifies in<br />

tandem with the range of products, raw<br />

materials and colours. For example, 30<br />

different materials are needed just for a<br />

premium model on behalf of pushchair<br />

brand Stokke. These include base<br />

plastics like ABS, polypropylene and<br />

polyamide with varying proportions of<br />

fibreglass. It is not unusual for pushchair<br />

parts to be produced on several<br />

machines simultaneously. After all,<br />

as a global player, Stokke markets its<br />

products right around the world.<br />

The materials used are repeatedly<br />

changed at customers’ request. “As<br />

far as the future is concerned, we<br />

foresee a trend away from PA and<br />

towards PP, driven by sustainability<br />

considerations,” says Fassotte. In<br />

future, the proportion of recycled<br />

plastics is poised to rise significantly,<br />

but sufficient quantities of recycled<br />

matter cannot be relied on for every material. “In that<br />

case, it is very difficult to ensure stable material flows,”<br />

believes Fassotte.<br />

On this point, a new Wicro client from Scandinavia<br />

has adopted a wholly new approach for the market<br />

to achieve a closed cycle. “The first high chair made<br />

of recycled PP partially mixed with wood fibres will<br />

shortly be celebrating its debut at an international<br />

trade show,” Fassotte reports. “This customer is<br />

deeply committed to drastically reducing its carbon<br />

footprint,” she explains. “This includes manufacturing<br />

the moulds in Europe and introducing a product takeback<br />

system to recondition the products and recycle<br />

them completely once they reach the end.”<br />

Wicro Plastics is constantly confronted with new market<br />

conditions as the demands on injection moulding<br />

processes also evolve. Currently, for example,<br />

<strong>EN</strong>GEL’s first assistance systems – iQ weight control<br />

and iQ clamp control – are being tested in production.<br />

During the injection process, iQ weight control<br />

analyses the injection pressure graph with a reference<br />

cycle and automatically adapts the individual injection<br />

profile, switchover point and holding pressure profile<br />

to current conditions for every cycle. Fluctuations in<br />

the environment and the raw material are automatically<br />

compensated for in this way, before even a single<br />

<strong>EN</strong>GEL is really<br />

helping us to<br />

achieve our goals.<br />

Evelien Fassotte from Wicro Plastics<br />

is proud to be a Wicronese.<br />

reject moulding is produced. Since recycled matter<br />

is naturally subject to greater batch fluctuations than<br />

virgin materials, the assistance system unlocks significant<br />

potential. With the assistance system, Marcel<br />

Kessels is aiming to attain consistently high production<br />

quality in the processing of recycled matter. “I am<br />

confident that by working with <strong>EN</strong>GEL, we can take<br />

another step towards raising both quality and the<br />

flexibility of production.” Another key aspect when<br />

using digital iQ products will be the faster machine<br />

start-ups. “After a colour change, it is important for us<br />

to resume the continuous process quickly.”<br />

“Everyone is proud to be a Wicronese”<br />

Having been active in the plastics processing market<br />

for more than 25 years, Marcel Kessels has decades<br />

of experience. On a tour of the production facility,<br />

an attentive observer will notice an <strong>EN</strong>GEL injection<br />

moulding machine bearing his name<br />

and his likeness beaming out from<br />

the <strong>EN</strong>GEL green. “This is an honour<br />

bestowed on employees who have<br />

been with Wicro Plastics for more than<br />

25 years,” he smiles – less a marketing<br />

gimmick than a big sign of respect for<br />

the employees in question. Indeed,<br />

experienced employees are essential<br />

to Wicro when it comes to meeting the<br />

challenges of the market through innovation<br />

and creativity. “Everyone is proud<br />

to be a Wicronese,” says Fassotte.<br />

Despite the challenges it entails, Evelien<br />

Fassotte believes that highly flexible<br />

production – involving numerous<br />

mould changes, high product diversity<br />

and very short delivery times – adds<br />

up to a distinct competitive advantage.<br />

“<strong>EN</strong>GEL offers outstanding support<br />

to help us meet our goals.” Effective<br />

interplay between reliable injection<br />

moulding machines, quick service<br />

and Fast Track machines is every bit<br />

as important to a company as ‘time<br />

and space’.<br />
