Procedures and materials

The production and processing of cast parts.

Casting permits free design of the part geometry and gives you the design freedom for a functionally optimised layout of the part contours. The wide variety of materials allows a part to be produced that is optimally suited to almost any purpose, e.g. in terms of strength and wear properties, corrosion resistance and operating temperature.

The most important casting methods are sand casting, including hand moulding and machine moulding, and lost-wax casting (investment casting with a ceramic shell mould). Heat treatments such as normalising, soft annealing, hardening and tempering increase strength and hardness.

The casting types include cast steel (structural steel, low-alloy steel (tempering steels), high-alloy steels, chrome steels, heat-resistant steels), cast iron (ADI, CADI, chilled cast iron, grey cast iron, spheroidal graphite iron) and aluminium sand casting. In addition, we develop and produce cast parts from customer-specific materials.
