Manufacture of rubber mixtures

The rubber mixtures for our products are manufactured by our cooperation partners according to our specifications. This allows us to utilize a diverse portfolio of rubber mixtures such as EPDM, NBR, FKM, FFKM. By setting specific requirements and conducting quality control checks, we are able to intervene early in the manufacturing process and thereby guarantee consistently superior quality.

We utilize injection molding, pressing, extrusion, and vulcanization processes to manufacture our products. The production of smaller series and custom orders is conducted directly in Berlin and Brandenburg. Large-scale production primarily takes place in Germany, Sweden, Poland, and England. We maintain constant communication with all our production partners and monitor each production step in accordance with ISO 9001:2015 standards.
