Lost Foam Adhesive

Lost Foam Casting is a mainstream process used for high production volumes where the repetitive demands can justify the high initial mould and tooling costs. The need to produce the initial foam pattern repeatedly necessitates the production of a relatively expensive mould tool with a cavity that replicates the desired component with risers, gates and runners.

In 1980s, the process of Investment Casting was well established and General Motors (GM) adopted it to produce automotive components.
