Elastomer & Plastic Parts

Our portfolio covers versatile requirements, whether sealing elements for particularly complex applications or plastic parts with a high demand on the look and feel. All parts are manufactured, extruded, assembled or moulded according to your drawings. We are happy to contribute our know-how to the development process: With over 20 years of experience in dealing with elastomer and plastic parts, we provide you with sound practical knowledge. This applies to the dimensioning of a sealing element and to special requirements such as drinking water resistance according to KTW, coatings or fabric inserts. Our portfolio includes all basic elastomers depending on your needs regarding temperature and media resistance, hardness and geometry.

Our Products


The supposedly trivial construction element is still used in various static and dynamic applications. We serve every customer-specific dimension in the material that meets your requirement profile. On request, we facilitate using a release agent such as graphite or talc and coatings as well as jacketing with PTFE.
