Definition

When we speak of iron casting, we have not only the series or one-off cast item in mind. Instead, we deliver integrated solutions: from design support and pattern, core and mould making through to melting, heat treatment, fettling, surface treatment, machining and complete, ready-to-install assembly.   

Production process

Whether it concerns a small-, medium- or large-scale series, our manufacturing process includes comprehensive consultation on request, including prototype, pre-series and series development as well as product optimisation. We find the best solution for your applications, from materials to manufacturing processes, castability check, simulation, design, lightweight construction and component optimisation.

Benefits

We bring the right experts together for excellent results from cast iron. Close cooperation with the customer, comprehensive development and materials expertise as well as the flexibility and proficiency to meet complex requirements are what sets us apart.  We fulfil customer requests with precision, including where quality and supply logistics are concerned.

  • From development to ready-to-install and pre-assembled series components
  • High materials expertise for a great variety of grades
  • Rapid prototyping (3D printing for pattern and core making)

Materials expertise

Our range of materials includes all grey and ductile cast iron grades according to DIN EN 1561 and DIN EN 1563. Special alloys and alloys to customer specifications, incl. EN-GJV (vermicular graphite cast iron), EN-GJS-XSiMo and Ni-resist alloys round out our production range.
