We manufacture standard parts with maximum precision in grey and nodular cast iron and special alloys on our fully automatic moulding plant.

High quality, precision modelling equipment and core boxes made of metal and plastic ensure maximum trueness to size and uniform high quality.

Depending on the geometry and required core stability we use Croning or cold-box cores; in many cases a combination of these two core systems can prove particularly economical.

Our sophisticated core technology provides a guarantee for perfect flow-enhanced internal contours and makes it possible to drastically reduce the size of the components. In addition, it minimises the need for expensive mechanical machining processes.
