Our philosophy
A component made of plastic should
be dimensioned, in a way to respect
the requirements but without having
unnecessary safety properties. Every
type of over-dimensioning has got
negative effects, both economically
and technologically. Only through
experience, know-how and creativity,
this target can be achieved.
“According to requirements –
no more and no less”

“We offer an experience of 40 years
about processing and machining
and dimensioning
of high performance polymers”
Know-How
Since 40 years we resolve problems, that come
into being using plastic for machine elements.
During this period, we have introduced successfully
high performance polymers ZEDEX ®
in application fields, considered visionary.
We learnt a lot in our path, but our valuable
Know-How´s spring are the 35 years test values
of materials and components. In the future we
let this spring fortifies and quicker, than up to
now, gushing out, in order that it shows us the
limits and capability of our high performance
plastic. Obviously we test also the competitors´
products, not only for a comparison of performances
with our products, but as well as to
inform our customers about the limits of the
competitors´ products.

Creativity
Valuable creativity is restricted by ignorance, lack of foresight,
communication problems and the resulting limitations. A product
passes through more steps during its developing. Normally
the processing is the bottleneck of your creativity, and it does
not let your idea to be incorporate in the product. In the same
way, the designer has not got any possibility, to be creative in
doing the material formulation. Besides, unwanted aggravating
influences are added between the various processes, such as
properties changes of the material by machining for example,
in which the processing condition are often not specified at the
time of the processing. The interactive influence and the information
flow between the various processes can be efficiently
used to determine the product conception. From the idea to the
end-product, we establish all the process steps of the product
developing and we can always react flexibly and creatively
realizing a successful product.
“From the idea to the end product –
all in one hand”

Research, Development
Research and development build the foundation of our success.
Through intensive research and continuous development of
materials, our high performance plastics ZEDEX ® have exceptional
properties. High performance plastics ZEDEX ® are used
in fields, where previously the use of plastics was unimaginable.
We are able to integrate the required properties in existing
high performance plastics ZEDEX ® by polymers modification.
The lead times of these special pieces are often not too long
and frequently big quantities are not required.
Thanks to our extensive testing facilities, we can determine specific
values, through specific tests:
– density
– friction value (stat./dyn.,
– moisture, residual moisture content dry/ lubricate)
– melt viscosity (MVR, MFRB) – PV-value (movement nuts,
– ultrasound test
bushings, gears)
– traction, pressure, three-point bending – dielectric strength
– creep curves
– surface resistivity
– heat distortion temperature – volume resistivity
– heat capacity
– colour measurement
– impact-strength test notched
(CIE Lab)
– ball indentation hardness and – FTIR spectroscopy
Shore hardness
– melting temperature
– fatigue strength
– glass transition temp.
– microscope´s enlargement 220-times – crystallinity degree
– surface roughness, surface profiling – flexural E-modulus
– surface tension
– th. expansion coefficient
– wear value (all contact conditions,
motion curves, lubricate)
“Research and development –
the foundation of our success”

Product requirements
Our duties are related to the following fields:
– maintenance-free
– dry running condition
– wear resistance
– low friction
– high precision
– mechanical strength
– thermal stability
– chemical resistance
– thermal conductivity

Customer service
In our company, a professional
customer service is very important.
We advise you regarding all
your doubts about the thermoplastic
synthetic materials and
the high performance polymers.
If you have got problems with
plastic components, we support
you from the analysis to the
solution and the shipping of the
problem-free products.
“With us you have got a
contact person for all the cases”
Our customer care includes:
– assistance to evaluate the
problems
– analysis through questionnaires
– personal helpdesk on site
– training courses and
conferences
– calculation software for
customers
In failure cases of your components,
we can mostly determine
the cause of the malfunctions
through mechanical tests, thermal
tests, micro or macroscopic
examinations of the defective
parts. Optionally, we recommend
you our appropriate high performance
plastic ZEDEX ® .

Calculation
& Design
We are glad to lead for
you the required calculations,
the material
selection and nevertheless
to determine
the planning process.
We provide our support
dimensioning your
technical components and
designing them suitable
for material, processing
condition and applied
load. We inform you about
the optimal shape and
thus, how to obtain the
maximum efficiency. You
will receive an estimation
of your components´
lifetime, corresponding to
your requirements, and
information pertaining to
the optimal ratio between
costs and usefulness.
We are professionals
in tribological polymer
solutions. We calculate
for your components, with
the help of the analytical
(FEA) and the finite
elements methods (FEM),
from the static to the
dynamic load, through the
tribological and thermal
load of your components.
The main tasks are related
to the following fields:
– plain bearings
(hydrodynamic as well)
– spindle nuts
– track rollers
– gears
– various sliding and wear
elements
Test our Know-How for:
– new constructions
– problem solving
– reconstructions
– components substitution
– functions integration
– cost reduction
“We inform you about the
optimal shape and thus, how to
obtain the maximum efficiency.”
