Detailed Product Description

Engineered Plastics

manufacturing concept      
We have invested in the specialist equipment necessary to manufacture components to the highest quality standards.

Our skilled team of engineers can assist and advise in the initial design stage or where process improvement is

required. We are constantly improving our manufacturing methods with the aim of further increasing our legendary

reputation for service and delivery.
    
production tolerances     
The machining tolerances required for thermoplastic parts are generally considerably larger than those normally

applied to metal parts. This is because of depending on the material -the higher coefficient of thermal expansion,

eventual swelling due to moisture absorption and possible deformations caused by internal stress-relieving during

and after machining.
The latter phenomenon mainly occurs on parts where machining causes asymmetric and/or heavy section changes. In

these cases, a thermal treatment (stress relieving) after pre- machining and prior to final machining of the part

might be necessary.
As a rule of thumb, for turned or milled parts, a machining tolerance of 0,1% to 0,2% of the nominal size can be

applied without taking special precautions (min. tolerance for small sizes being 0,05 mm). In this respect, the ISO

2768, the DIN 7168 as well as the Swiss VKI-recommendations & tolerances for machined plastic parts can be used as a

guide.
    
quality makes the difference     
Quality is at the core of everything we do. We make every effort to deliver highest quality EPP or AEPP products

that meet our customers' needs. We are constantly striving to enforce and improve our quality standards, since

customers demand the highest quality engineering plastics solutions to compete in their highly competitive markets

and thereby gain a competitive edge on their competitors.
    
materials general informatio     
Only high performance materials can meet the demands of the marketplace today and tomorrow. For this reason, we have

invested in a state-of-the-art R&D centre at our Austrian group headquarters to constantly improve our materials.

Next to our own range of Engineering plastics, tailor made compounds and elastomers we use Quadrant as a preferred

supplier to offer the widest range of parts to answer your application needs.
The family of polyurethanes for instance, is renowned throughout the world. This in-house expertise in the field of

polymer science, combined with close co-operation with universities, has given us a truly world class range of

materials.
              
EPP and AEPP- material range comparison     
The figure below shows the wide range of AEPP materials we are offering to our customers. The figure describes the

hardness of the materials in the Shore D scale (maximum hardness in Shore D is 100, which would be covered by steel,

stone and crystals for example) as a function of the modulus of elasticity (the modulus of elasticity is a physical

constant describing the stiffness of a material or the resistance of the material against deformation). Compared to

common AEPP manufacturers, that are mainly working in a modulus range above 200 to 300 MPa, which means the

materials must have a minimum hardness because of machining properties of the parts, We can also offer parts made of

lower modulus and hardness. This is due to the fact that We has over 15 years experience in treating elastomeric

materials with a hardness below 50 Shore D by manufacturing sealing elements. We are also able to produce technical

parts made of such materials by milling and complex machining techniques.
