Customer-specific solutions – customised seals for specific areas of application

Increasingly elaborate and complex applications pose ever-higher requirements for reliable and secure sealing. Where this cannot be achieved with standard seals, we make every effort to work with you to find an optimal individual sealing solution.

We use a drawing or a model to develop and produce customer-specific metallic seals from various materials such as copper, aluminium, soft iron or stainless steel. Even a surface finish (electroplating) does not present a challenge for us. In addition to the prototype construction under series conditions, we can also offer you small series and quantities quickly and flexibly. We will be happy to provide you with prototypes and sample parts for testing under authentic conditions.

Our customer-specific solutions can be retrieved at any time. We do not keep the seals in stock, but we archive the tools that we have created in order to guarantee fast repeat production.

Flat seals

Flat seals

The optimal application for metal seals for a flat surface is one that guarantees sufficient surface pressure. The seal can be sufficiently plastically deformed so it fulfils its optimal sealing function. According to your technical requirements, we can produce flat seals from various metals and also electroplate surfaces on request. We also offer you our flat seals as a standard part, for example according to DIN 7603.

Profile seals

Profile seals

Seal surfaces with a circumferential profile can improve sealing properties in particular situations. These may, for example, be present if it is not possible to achieve sufficient surface pressure for the required plastic deformation of a pure flat metallic seal. The plastic deformation of profile seals is easier with a comparatively low tightening force, enabling them to achieve their sealing function. Depending on the application, you have a choice between various profiles, materials and surface finishes. We can also agree on other profile solutions and materials with you and produce them according to your individual requirements. We also offer you profile seals as a standard part

Filled sealing rings

Filled sealing rings

Filled sealing rings are combinations of metal and an elastic filler material. These sealing rings are used whether a high tightening torque can be achieved. Due to its elastic properties, a filled sealing ring adapts well to the sealing counterface even with a low tightening torque. According to your specific technical requirements, you can choose various filler materials and metal sheaths and their electroplating for an optimal sealing function. We also offer you filled sealing rings as a standard part.
