Competence in Iron Castings
Our products
Our materials
Our range of materials extends from all grey and ductile cast iron grades in accordance with DIN EN 1561 and DIN EN 1563 up to special alloys in conformity to our customers' specifications. The production spectrum is rounded off by even more high-quality materials, such as EN-GJV, EN-GJS-XSiMo and Ni-Resist alloys.
Process development
We attach special importance to advisory services tailor-made for the individual customer – ranging from component design, via materials selection and machining, up to and including the installation of ready-to-run components. Simulation tools and 3D printing technologies assist at all stages of the process, in order that the shortest possible lead times can be achieved for design, tooling up and prototyping, right up to readiness for series production of the components. These benefits have made us a valued development partner for our customers in the automotive and mechanical engineering industries.
