ZOLLERN supplies sophisticated solutions for diverse applications through its business units drive technology, plain bearing technology, foundry technology, mechanical engineering elements and steel profiles.

Sand castingSuperior quality casting

In Laucherthal, castings have been made from metallic materials since the founding of the company in 1708. Apart from iron and steel, a bronze foundry was added around 1890. The emphasis today is on sand castings made of copper and copper alloys as well as high and low alloy steels.

For manually or machine formed parts, resin-bonded sands are used. This ensures a good surface, narrow tolerances as well as high-quality material. For special applications or requirements, we have the shell moulding process or utilisation of ceramic moulds and ceramic cores at our disposal.

Castings from copper alloys are possible to a delivery weight of approximately 7,000 kg, from steel to approximately 2,000 kg. Equipped with highly modern CNC machines, our machining workshops pre-process or finish castings according to customer drawings. In the laboratory and materials inspection, all standard destructive and non-destructive tests and examinations are available. Production is certified according to DIN EN ISO 9001 : 2008. For us, quality and delivery reliability are the prerequisites for success on the national and international market.
