Permanent mould casting enables castings to be produced with excellent mechanical and physical material properties and close to their final dimensions. This casting method satisfies many of the typical criteria for steel and provides a wide range of methods for creating individual shapes.

Shorter machining times and zero-waste production mean that permanent mould casting can drastically reduced product costs. The areas of use for our permanent mould casting are almost unlimited. It has proven itself wherever these requirements must be met.

With our proven materials, we meet the highest requirements:

  • HK special casting GGK for the low and medium pressure
  • Continuous nodular casting GGGK for high pressure

Both materials are characterized by a fine-grained, dense structure completely. These excellent properties are targeted by the cooling of the molten iron reached in permanent metallic moulds.
