Food Compliant Plastics

Our high-quality finished parts made of engineering plastics are used in many applications, such as in filling, mixing and portioning systems in contact with foodstuffs.

Plastics are subject to different physical laws than metals.

The up to 10-fold greater thermal expansion, the volume change due to moisture absorption and subsequent dimensional changes due to the reduction of residual stresses in the long-term behaviour preclude the guarantee of narrow dimensional tolerances.

By tempering, we mean a heat treatment to achieve the following properties:

• Reduction of internal stresses caused by extrusion or machining
• Crystallization enhancement for strength and chemical resistance
• Increase dimensional stability over a wide temperature range
