Chemical & plastics

The chemicals and plastics industries are spending a lot of money on maintaining and purchasing vacuum pumps and vacuum-related equipment. In the chemical industry the pumps are exposed to a lot of aggressive chemicals that require resistant vacuum pump materials. Vacuum automation solutions in the plastics industry have to face challenges like unloading of high temperature parts with textured surfaces but also mark-free and PWIS-free (Paint Wetting Impariment Substances) requirements.
