Service

GK provides an one-stop solution for prototype sand castings.

Eleven 3D sand printers are operating in Germany, Japan and the USA.

Engineering

GK has extensive experience in aluminum body and white, chassis, battery housing and power train applications by supporting the global OEMs from the initial engineering phase. We consider and implement the requirements of mass production in prototyping.

Our one-stop casting solution provides support in part design, sand casting prototypes, and mass production designing.

Sand casting prototypes

Our sand castings provide quick prototypes with low initial cost in comparison to die cast parts. Our unique low pressure sand casting process is capable of minimal wall thickness of 2mm and has comparable properties to mass production parts.

Our 3D sand printing process "DMP" operates in Germany, Japan and the USA to directly print sand molds without any conventional patterns.

Our low pressure sand casting process can also be used for small-lot production parts up to 3,000 pieces per year. LPSC has high repeatability in quality which provides a flexible procurement option for low volume applications. In addition, sand castings have the possibility of more freedom in part designing.

Applications such as limited series vehicles are optimal for our production.
