Experienced supplier to the automotive industry
Let us find the solutions to current and future automotive challenges together!

Solutions for automotive engineering

In a wide range of areas,the company offers solutions that perceptibly improve the life span, economic efficiency and comfort of a vehicle. This includes, for example, decoupling elements, ducts, return lines, fluid lines, curved near-engine components and precision bellows.

The Product Range

We are one of the leading companies in the market

Engineering competence in each phase

Our engineering expertise from the initial customer contact to the optimal production design is one of our core strengths. This is what has made us the global market leader in our industry.

Development / Prototype Construction

Well over 1000 analysed operational loads and calculation models form the basis for our precise design optimisation. To reach physical tests quickly we have, for example:

  • machine and prototype construction
  • 3D printing support

System partner

We use our experience to support our customers in system design and validation. So we supply production-representative prototypes and calculation models compared with them, whose characteristics are tuned to the system behavior. It is important for us to ensure the function of our products in the system and thus to contribute to an optimal overall result.

Operational loads determination

Thanks to many years of experience both in building capable measurement systems as well as in the interpretation of the various customer test tracks and driving manoeuvres we can calculate the lifespan of our components quickly and precisely, allowing us to offer a design optimised for particular applications.

Validation of operating strength

Simulating the life of a vehicle in the shortest possible time requires precise knowledge of the interplay of all relevant operating loads, competence in computational analysis and fast, highly precise test bench technology.
Our calculation and testing methods allow us to represent an entire vehicle life on the test bench within a few days.

Corrosion Resistance

Thanks to the systematic analysis of components after their use in customer testing and in the field, we know the demands placed upon our products very well. A large number of analysed components forms the basis for the world's largest database of returned parts.
