Automotive engineering

Our products are used in the electric drive systems of vehicles, where the conductor is often subjected to powerful external forces such as switching surges, oscillations or vibrations.

They are also found in all applications where a rigid connection is not possible on devices and machines, such as in cars and electric rail vehicles or in ships and airplanes.

Fields of application:



We combine the various different components from our product portfolio into individual, long-lasting connecting elements of the highest quality according to specific customer demands. At the same time, we also use our years of experience to find a solution for – and together with – our customers that is technically and economically optimised.
