Progress based on tradition 

"There is no past without the future" 

Egon Fridell 

Since the Company's founding in 

1890 SCHERDEL has always 

demonstrated an innovative approach, 

of the SCHERDEL "Ultra" process in 

1956 as a solution to thermal problems 

relating to valve and clutch springs; 

committed to progress. Now, as in the

regarded as an opportunity for growth 

always been an outstanding feature of 

and rationalization. As early as 1915 

the SCHERDEL Management – start- 

SCHERDEL was using automatic

History 













"Reaching a limit shouldn't mean: This is where you stop, but rather: 

This is your chance for growth" 

Think globally – act locally: today, 

true to this motto and with 26 

locations worldwide, the SCHERDEL 

Group can always provide its clients 

with a locally based service. With 

the single European market in mind, 

the course was set at the end of the 

1980s for the successful internationalization 

of the Company. This policy of 

expansion began with the take-over of 

existing firms in France and Portugal. 

Following German reunification, an 

important member joined the Group – 

the Marienberg spring-production factory 

in Saxony. SCHERDEL then 

looked towards Eastern Europe, and 

companies were founded in the Czech 

Republic, Slovakia and Poland. The 

activities in relation to new locations 

have focused on the USA, Brazil, 

Mexico and the growth market Asia, 

the emphasis being on China. 

SCHERDEL Group Managing Director, 

Walter Bach, has declared that, in 

addition to the internationalization 

of Company locations, future Group 

policy will focus on enhanced quality 

and efficiency.

History 













"The slightest movement affects the whole of nature" 

Blaise Pascal 

In relation to the manufacture of 

engineering springs and the expertise 

that this requires, the SCHERDEL 

Group has led the field for more than 

100 years now. Here, engineering 

springs are often used to solve problems 

which demand the highest technical 

standards. The valve spring, for 

example, is a small but nevertheless 

highly stressed component for piston 

engines. Its quality is crucial to the 

service life of an engine. Particularly in 

relation to the design and manufacture 

of valve springs, SCHERDEL possesses 

outstanding know-how and many 

years of experience. After all, the 

world's first diesel engine was 

equipped with SCHERDEL valve 

springs. However, engineering springs 

are not only used in the manufacture 

of motor vehicles (e.g. for gears, ABS, 

fuel injection, carburettors, braking 

systems), but also in the building and 

furniture industries, in measuring and 

control technology, in the manufacture 

of various types of appliances, and in 

electrical engineering and electronics 

(e.g. switches). In addition to the valve 

springs already mentioned, the range 

of products includes compression 

springs, tension springs, disk springs, 

torsion springs, retractor springs, constant 

force springs, spiral springs, 

sleeve springs and also spring elements 

for oil distribution rings. 

Engineering springs are the invisible 

helpers and problem-solvers in a modern 

world which would certainly be less 

mobile without them.


History 













"For the whole must be prior to the part" 

Aristotle 

SCHERDEL'S engineers and 

development technicians always 

have the whole product in view when 

they play their part in enhancing the 

standard of comfort and convenience 

in modern vehicles. Criteria such as 

safety, weight reduction and functionality 

are also of prime importance in the 

manufacture of metal structures for 

vehicle seating. Often enough it is in 

assembly components that the engineering 

spring – one of the 

SCHERDEL Group's core products – 

really comes into its own. No matter 

whether it's a question of adjusting and 

compensating components with spiral 

springs, switch systems, or mechanisms 

for adjusting and actuating 

systems: in the development and 

manufacture of these products the 

emphasis is on cost optimization, long 

service life and reliability. Today, in 

close co-operation with the automotive 

industry, the ideas for tomorrow's 

vehicle components take shape.


History 













"I bend but I do not break" 

Jean de La Fontaine 

Of course SCHERDEL's stampings 

and shaped components are 

flexible problem-solvers, but when it 

comes to the crunch they can take any 

amount of punishment. There are 

innumerable products in this field: wire 

rings for fastening or for use as circlips, 

contact elements and blanks, 

terminal housings for electric motors, 

retaining elements for windshield 

wipers, contact components for vehicle-seat 

heating systems, hinge 

elements or shielding plates and 

retaining belts, to mention but a few 

items from the extensive production 

program. In the manufacture of stampings 

and shaped components, precision 

is particularly necessary when 

working with material thicknesses 

down to 0.06 millimeters. These components 

have a wide range of applications 

and an equally impressive range 

of customers from widely varying 

fields: the automobile and automotiveparts 

industries, manufacturers of 

household, electrical, sports and 

leisure articles, or the furniture industry.


History 













"The greater a thing's unity, the more perfect its goodness and effectiveness" 

St. Thomas Aquinas 

If it's a question of guaranteeing reliable 

connections in the field of automotive 

engineering, then hose clamps 

made by SCHERDEL are the answer. 

Whenever tube and socket connections 

must be perfectly sealed to ensure 

the reliable functioning of technical 

components, then dependable, 

maintenance-free hose clamps provide 

the ideal solution. Since they are selfadjusting, 

they adapt to varying environmental 

conditions and ensure 

complete functional adherence despite 

the constantly changing service conditions 

in a motor vehicle. In order to be 

able to offer all its customers the 

greatest possible expertise in the fields 

of development and production, 

SCHERDEL, as a leading producer of 

coil springs, founded a joint venture 

under the name of TOGO SCHERDEL 

with the Japanese Togo Seisakusyo 

Group, which is the market leader in 

the field of hose clamps. Thanks to the 

combined know-how available in this 

partnership, they can produce standard 

and space-saving hose clamps, as well 

as pretensioned and double hose 

clamps with outstanding design-related 

advantages and enhanced efficiency. 

These products are particularly suitable 

for use in coolant circulation systems, 

servo systems, fuel systems, chargeair 

and air-intake systems or for direct 

injection processes under variable 

overpressure or vacuum conditions.


History 













"It is through the laying of foundations that greatness of any 

kind achieves lasting fame" 

Ernest Renan 

Whenever product development 

work involves laying the foundations 

of new systems and components, 

then SCHERDEL's Assembly 

Technology Division can provide the 

necessary expertise right from the 

start. No need for the customer to get 

involved in development and assembly 

work or logistics. Instead, he can order 

individual parts or complete components 

ready to be installed, in small 

lots or large numbers, as required. The 

careful co-ordination of a wide variety 

of materials and possible coatings, 

combined with cost-effective assembly 

concepts, ensures an optimum service. 

Whether it's a question of manual work 

or fully automatic series production in 

three shifts, continuous quality checks 

guarantee that even the most stringent 

customer requirements are satisfied. 

The range of products made by the 

Assembly Technology Division includes 

spring packs for automatic transmission, 

spring supports for vehicle 

tailgates, return springs for variable 

valve-train systems in engines or, for 

example, pre-assembled tambour door 

systems with integrated torsion springs 

for the furniture industry.


History 













"For it is the spirit alone that brings technology to life" 

Johann Wolfgang von Goethe 

Machines and systems would 

be of little value if they didn't 

originate from some ingenious idea, 

the realization of which opens up new 

possibilities, reduces costs, rationalizes 

work processes or even improves 

conditions at the workplace – by 

reducing noise, for example. Working 

at top speed and with total precision, 

the CNC milling machines produced by 

the SCHERDEL Group can perform 

any task in the field of wood, plastics, 

aluminium and metal working. Using 

movable portal machines or mobile 

supporting tables, workpieces and 

semi-finished products can be given 

careful 5-axis treatment from start to 

finish, with only one initial clamping 

procedure. The range of products 

also includes coordinate and singleaxis 

tables, tool magazines and toolhandling 

systems, pallet-exchange 

systems and machine housings. 

SCHERDEL's special wire-working 

machines rank among the top 

products in their segment of the 

market. For projects involving the 

modernisation of existing heavy 

machines, committed engineers and 

technicians work out individual solutions. 

Here, state-of-the-art production 

techniques and calculation methods 

guarantee that today's machines will 

be able to meet tomorrow's challenge.

"The way is the goal" 

Buddhist maxim 

H 

ow can we ensure that the way 

to our goal is as fast, as accurate 

and as smooth as possible, so that in 

the case of repetitive handling operations 

no variations or deviations occur? 

Finding an answer to this question 

resulted in a world patent: the 

ZARIAN ® -Z2 drive principle, a 

SCHERDEL Group invention consisting 

of a toothed belt which rolls on a 

toothed rack mounted parallel to a 

guide mechanism. This invention provides 

the basis for linear modules and 

multi-axis systems, skilfully combined 

with ingenious control techniques and 

peripheral devices such as grippers. 

This not only optimizes workstation 

procedures but also relieves staff of 

the task of carrying or lifting heavy 

loads. The system uses portal loaders 

which can handle heavy components 

and perform difficult lifting operations 

with the greatest of ease. Thanks to 

modern, automatic assembly equipment, 

production time can be reduced 

considerably – another cost-saving 

advantage. The field of automation 

and control technology also includes 

the development of all-in-one solutions 

comprising the construction of individual 

special-purpose machines with 

corresponding software development 

for SPC and CNC control systems 

including the construction of control 

cabinets.

"If you want to do a good job, only the best tools will do" 

Johann Wolfgang von Goethe 

I 

n tool-making SCHERDEL aims to 

meet the highest standards. Here, 

inspiration and creativity, combined 

with careful planning and the expertise 

to know what is technically feasible, 

provide the basis for the design and 

manufacture of highly complex tools. 

For this work, the SCHERDEL Group 

can call on the experience of a highly 

committed staff and state-of-the-art 

technologies: modern CAD equipment 

with online data transfer to the customer 

is used for the production of 

3-D models. In the developers' network 

this 3-D data generates the technology 

programs for controlling the machining 

process. The DNC data-networked 

machinery includes efficient facilities 

for wire-EDM and NC three-axis and 

five-axis machining, as well as HSC 

milling machines for high-speed cutting, 

or pressing and stamping 

machines able to exert a pressure of 

up to 600 tonnes. SCHERDEL's 

expertise is also evident in the manufacture 

of punching, bending and 

stamping tools, jigs and fixtures, reference 

gauges, follow-on composite 

tools and transfer tools, isostatic 

pressing tools and peripheral equipment 

for automatic handling machines. 

Here, SCHERDEL has set standards 

of quality and precision which are hard 

to beat.

"Values can only be preserved by change" 

Richard Löwenthal 

B 

y applying special coatings to 

alter the surface finish of technical 

components, corrosion can be 

prevented and their service life can be 

considerably enhanced. However, the 

characteristics of the material of which 

the parts are made can also be modified 

in such a way as to produce functional 

advantages: for example frictional 

resistance can be reduced, or 

protection can be provided against 

acids, alkalis and contact corrosion. In 

the field of surface finishing, the 

SCHERDEL Group not only has the 

necessary know-how but state-of-theart 

technology as well: the equipment 

includes a computer-controlled zincphosphating 

unit which also sets standards 

in relation to environmental protection, 

a TULZ installation for coating 

parts with complicated geometry, 

standard Delta Tone and Delta Seal 

installations, modern spraying equipment, 

as well as powder-coating and 

electro-dip-coat (KTL) installations. 

In the central laboratory there is a 

scanning electron microscope for 

documenting layer formation. The 

scientists' work also includes quality 

assurance involving the preparation 

and examination of metallographic 

sections and the use of equipment for 

salt-spray, Kesternich and damp-heat 

testing procedures.
