CAST COMPONENTS & ASSEMBLIES

From Individual Cast Components to Ready-to-Install Assemblies – All from a Single Source.

With comprehensive downstream processing capabilities, SDS offers far more than the production of high-quality cast components, drawing on the manufacturing expertise of the Schmidt + Clemens Group.

Heat treatment, precision machining through turning, milling and drilling, as well as professional welding capabilities, enable the manufacture of complex components and complete assemblies. For our customers, this means seamlessly coordinated processes, the highest quality standards and fewer interfaces – all from a single source.
