At our site in Fröndenberg/North Rhine-Westphalia, our employees are highly committed to ensure that a high level of customer satisfaction is achieved through optimum work quality and reliable delivery.

Thanks to modern vacuum furnaces, inert gas continuous furnaces and inductive units as well as a wide range of machinery for component production, a large number of innovative components can be manufactured at the Fröndenberg site.
