Unless otherwise expressly stated, the materials we use are steel (StW37) or high quality screws.

The used metal parts are protected against corrosion by electroplating or a coat of lacquer and are purchased from renowned German manufacturers.

If desired, we would be pleased to manufacture in other types of metal. Our prices are available on request.

Qualities of natural rubber

Unless otherwise stated, the rubber quality we use is natural rubber (NR) of approx. 55° SH.

We have a wide range of products of type NR of approx. 55° SH (medium) on stock. If you desire other degrees of hardness, a custom manufacture is possible and indispensable. However, you have to order minimum volumes – one or several mould filling/s each. We will be happy to indicate our prices and volumes.

We purchase the raw rubber mixtures processed by us, which are expressly high-quality mixtures, from renowned German manufacturers according to specially developed formulations. Regarding the mixing ratios, we place particular importance to a long life cycle and a very favorable dynamic behavior of the final product which we achieve by using state-of-the-art aging inhibition and other additives.

The mixtures are subject to a strict quality control so that we can continuously achieve uniform technical and physical values.

We are always ready to advise you on your individual purpose of application.
