Well-established and dependable

We produce high-quality aluminum castings tailored to the individual requirements of our customers in the automotive, electrical, and mechanical engineering industries. This primarily involves engine, drive, and chassis components as well as e-mobility parts.


Our product portfolio includes engine blocks, structural parts, clutch and transmission housings, oil pans, engine and transmission supports, and more. We supply customers not only with unfinished castings, but also with aluminum cast components ready for installation.

This is made possible by various internal work steps such as heat treatment, mechanical processing of the castings, surface treatment, and completion and assembly into finished components. +49 (0)39484 500
