In general, Kurtz sand casting machines offer a wide field of application: from chemically bonded sand molds, constructions with green sand molds to plaster molds for special parts with high demands on precise details.

Investment casting in ceramic molds even allows fine structures of 1 mm wall thickness. Versatile molds - different parts. The product range includes everything from small parts with only a few kilograms of weight to complete housings of 260 kg casting weight, from high-tech prototype single part to large-scale production.

From rapid prototyping to serial casting

There are several good reasons for the application of Kurtz sand casting machines. Therefore, Kurtz low-pressure die casting technology is also used in well-known foundries such as in the highest categories of international racing. Several teams already rely on the advantages of controlled mold filling and produce their prototypes and racing engines on Kurtz machines.

Automotive and more …

The automotive industry is certainly not the only sector which is interested in Kurtz low-pressure die casting technology with precise pressure control. Further applications are in the aerospace industry or in short anywhere where every gram counts in order to keep the mass of moving parts to a minimum. In this context, magnesium casting becomes more and more interesting as well. By far, aluminium is not the only metal cast on Kurtz low-pressure casting machines. This casting technology also has a huge potential - from aluminium bronze for ship building to magnesium for light-weight constructions in general.
