HYDRAULIC
POWDER PRESSES
FORMING THE FUTURE
The production of complex sintered compacts of
consistently high quality and on economic terms
are the demands facing the operators of powder
presses. The parts produced are used predominantly
in the automotive industry, but also in the electrical
appliances industry and in general machine engineering.
The industry finally recognised the benefits
of powder metallurgy in the 1950s, and since then
the technology has enjoyed rapid growth.
The development of new materials
and growing demands for “near-netshape”
are now presenting new
challenges, but at the same
time opening up new and
trendsetting opportunities for
the powder press technology.

LEADING IN PRESS
TECHNOLOGY
SMS Meer has played a leading
role in the further development
of the press technology
in powder metallurgy with
its innumerable innovations
from the very beginning.
The company has more than
60 years’ experience in powder
press technology. On the basis
of this experience, standards
were set in the machine engineering
of the powder presses
through continuous research
and development. For example,
presses with PLC and CNC
systems were produced as
early as 1985, followed in 1990
by a fundamental optimisation
of the valve, path and pressure
measuring technology allowing
presses with press forces
from 600 kN to 16,000 kN to be produced. A further
trendsetter was then the “controlled punch adapter”
(CPA) technology patented by SMS Meer. In addition,
the press concepts were expanded up to 25,000 kN
and the complete part handling technology was integrated
into the press. The experts from SMS Meer
use all their experience and knowledge to build new
plants and modernize older designs – so that even
decades later plant operators can still produce in line
with market requirements.

CNC PRESS TECHNOLOGY
TAILOR-MADE PRESSES,
FLEXIBLE APPLICATIONS
With the hydraulic CNC powder press and controlled
hybrid press (CHP) product range, SMS Meer is
able to offer the right solution for practically all applications.
The customer can choose from two press
ranges, each with different types and press forces,
allowing individual configuration to meet the specific
requirements. While hydraulic presses are based
completely on a hydraulic system, the hybrid press
series employs a mechanical/hydraulic drive system
for the upper ram enabling the advantages of a highspeed
mechanical system to be employed extremely
efficiently together with the precision of a hydraulic
system. Furthermore, the SMS Meer presses are
characterized by a compact form as a four-column
press with a low overall height.

OUTSTANDING TECHNOLOGY,
INTELLIGENT OVERALL CONCEPT
The CPA process technology developed and patented
by SMS Meer and the excellent implementation
of the hydraulic-mechanical drive were commended
with the EPMA Award. Compared with other systems,
the hydraulic CNC positioning during the
whole press cycle – and in particular in compacting
position – impresses with its high precision, product
quality, reliability and gentle operation. Coordinated
operating heights and arrangement of powder filling,
adapter changing systems and part handling equipment
round out the overall SMS Meer concept.

CPA – CONTROLLED PUNCH
ADAPTER
UNIQUE POWDER PRESS PROCESS,
UNIVERSAL POSSIBILITIES
The heart of the hydraulic CNC powder presses and
the hybrid presses is the controlled punch adapter
patented by SMS Meer. Equipped with up to 12
axes, it permits extremely flexible operation for the
production of highly complex sintered parts. With
the CPA technology, several punch levels interact,
controlled fully automatically and precisely by the
CNC system. SMS Meer offers a broad range of
adapter changing systems – from simple to fully automated.
Furthermore, the controlled punch adapter
has a well planned and easily accessible design for
simple tool changing.
PROCESS ENGINEERING OF THE
HIGHEST STANDARD
The powder is brought into the desired geometry by
controlled movement of the punches – and allowing
for their interaction – initially without applying the
compacting force. This creates a basic precondition
for the later uniform density of the compact. This is
followed by the coordinated press compacting process.
With the telescopic arrangement of the cylinders,
each CPA axis is guided extremely precisely
and can transmit high compacting forces. Thanks to
the hydraulic CNC axes, the force of all the punches
is applied uniformly and the punch expansion is compensated,
particularly during the relief phase.
The result: Compacts without micro-cracks. Furthermore,
the compacting process is made far more
precise and controlled for a lasting high productivity
and product quality.

COMPACTING PROCESS
1. Filling 2. Underfill 3.1 Start powder transfer 3.2 Powder transfer 3.3 Transfer position
The compacting operation using the CPA method by
SMS Meer is particularly efficient. It comprises seven
finely coordinated steps to guarantee optimum product
quality.
1. FILLING
For powder filling, the lower punches are already
pre-positioned in relation to each other.
2. UNDERFILL
To prevent powder losses when the upper punches
strike, the die form is stopped.
3. POWDER TRANSFER
The powder is displaced by individual punch move-
10
ments without pre-compaction. The powder transfer
position is reached when the powder displays the
uncompacted partial contour.
4. COMPACTION
The powder is now compacted in a controlled manner
– taking precise account of the parameters stroke,
time and pressure. In the process it is crucial that
all press punches reach the compacting point simultaneously.
5. PRESSURE BUILDUP
To compensate punch spring-back and rob the pressed
part of its rebound forces, the upper and lower punches
move up and down individually and concerted.

4. Compaction 5. Force reduction 6. Withdrawal 7. Release
6. WITHDRAWAL
The compacted part is carefully exposed and at the
same time held by the punches – thus preventing
cracks in the part.
7. RELEASE
Finally, the punches are moved back into their initial
position. The finish compacted part is released and
can be removed.

SAVINGS IN COST AND TIME
COMPLEX PARTS IN NEAR-NET-SHAPE QUALITY
The more precise the forming contour of metal powder parts, the less further machining is necessary. The
resulting savings potentials in time and costs are enormous. The CPA compacting method from SMS Meer is
far superior to conventional compacting methods as far as near-net-shape parts are concerned.
COMPARISON OF THE COMPACTING
METHODS
The diagram shows the difference between the CPA
compacting method and conventional compacting. At
the start of the controlled compacting movement, the
two methods are identical with respect to proportional
speed of the lower punches to the upper ram speed
(points 1+2 in the diagram). With the conventional
compacting method with fixed stop, a deflection point
is reached with the upper ram speed being followed
due to the insufficient counter-force (point 3). The
compacting position is then reached prematurely on
the mechanical fixed stop with final compaction being
effected only by the upper punches (point 4). With the
CPA compacting method, on the other hand, the process
is linear and uniform with all the controlled press
punches reaching the compacting positions simultaneously
with high counter-forces (point 5).

NEW APPROACH FOR
FUTURE TECHNOLOGY
Powder presses produce predominantly components for the automotive industry. Not so at Gobal
Tungsten & Powders (GTP). For this U.S. based company SMS Meer adapted its press technology
to a completely new application in a very short time period. With its HPM 1600E5i GTP manufactures
components for fuel cells. “SMS Meer supports us in developing a new market in the area of Green
Technology. Success in this process requires a combination of technology and efficiency which we
have found with SMS Meer”, says Mike Cuddy, Procurement Manager, GTP.
The HPM 1600E5i impresses with its precision, speed and high process reliability. The opti-
mized hydraulics warrant minimum energy requirements. This is how SMS Meer understands
customer focus.

PROCESS AND
QUALITY CONTROL
THE INTELLIGENCE OF THE PRESSES
The CNC system of the powder presses has a clearly
structured and easy-to-use operator interface. Machine
operators are therefore familiar with the machine and
its functions within a minimum of time. Easily comprehensible
programming applications, actual value/
nominal value real-time analyses, fault displays and
diagnostic functions are available. The process data
for repeat parts can naturally be saved in a database,
thus shortening the set-up time in the future.

BENEFITS AT A GLANCE
Easily comprehensible visualization

Fully automated quality control
Statistical evaluation for process or
production optimization

Oscilloscope diagram for all functions
Operation flow
Actual machine values Production values
AUTOMATED QUALITY FUNCTIONS
When data are entered, the CNC system performs
a plausibility check, thus helping to avoid operator
errors. It provides all the operating data for the compacting
process, monitors the sensors, compares
actual and nominal values and records all the vital
process data for quality assurance as part of the
statistical process control (SPC). With the continuous
quality documentation, plant operators can
meet the demands of the relevant standards or the
customer’s specifications without additional work.
Parameters monitored are i.a. the position and force
of the top and bottom punches and the part weight.
The compacting force curves of all the press axes
involved in the process are also monitored and
recorded in relation to their preset tolerances.
The statistical evaluations serve for both process
and production optimization on the machine and
for quality documentation. The CNC system can be
integrated into a network so that the recorded SPC
process data can be forward directly to the responsible
employee.
