Quality and certificates






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 GJL200, GJL250, GJL300, GJS350-22, GJS400-15, GJS400-18, GJS415-10, GJS500-7, GJS600-3, GJS700-2 and GJS800-8.

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.
