Melting practice






Two medium frequency induction furnaces are the core of our foundry. With a capacity of 8 tonnes each, we have chosen an energy efficient technical solution that is optimal for our range of parts. Both ovens run in parallel in the tandem process and are therefore alternately in the melting or holding process.

The quality of material is checked and documented repeatedly during the overall melting and casting process, in order to also be able to document the mechanical properties after the delivery and final assembly. In addition we are pleased to issue test certificates and carry out mechanical testing of materials.

The delivery of the raw materials is subject to very strict regulations and is carried out with great precision, in order to adjust the desired material markers. We can usually forego subsequent heat treatment by the use of high quality raw materials.

Our capacity includes a maximum output of 18,000 tonnes per year at present for various material markers.
We currently supply the material markers GJL-200, GJL-250, GJL-300, GJS-350, GJS-400-15, GJS-400-18, GJS-415-10, GJS-500-7, GJS-600-3, GJS-700-2 and GJS-800-8.

In our company we specialise in the manufacture of ductile cast iron. This involves a magnesium treatment with the aid of a one way wire spooling process after tapping the oven.
However, we also like to produce demanding customised castings from lamellar graphite cast iron.
