GSL Lost Foam: casting with Lost Foam

For burr-free castings and complex geometries

 

With our Lost Foam production line, we offer you a casting process that is both state-of-the-art and sustainable. Our more than 30 years of experience in Lost Foam steel casting is unique worldwide.

The Lost Foam process is primarily used when components with complex geometries and high demands on surface quality are to be produced in large quantities. Castings made using the Lost Foam process ensure dimensional accuracy, are free of burrs and require little finishing. The process allows low casting tolerances while enabling the production of particularly thin-walled castings for lightweight construction. Reducing high-cost fettling and machining means that the process is particularly cost-effective.

Lost Foam is also a very environmentally friendly process that uses no chemical binders in the moulding material, minimises noise and dust emissions and consumes very little energy. The combustion products generated by the foam patterns are completely captured during the casting process and treated in a waste gas purification system. This reduces emissions to such an extent that the process scores highly in terms of low environmental impact.

Our full service for your Lost Foam casting project includes all services from casting development to testing, delivery and warehousing.
