Lost Foam Casting

what is lost foam casting?

Lost foam casting is a type of investment casting that uses polystyrene foam as the pattern for the molten metal to follow. The foam is burned away during the casting process, leaving behind a cavity in the shape of the desired object.


This type of casting has several advantages over other methods, such as traditional investment casting. Lost foam casting is more cost-effective, since there is no need to create expendable patterns out of wax or other materials. It is also more precise, since the foam provides a consistent shape for the molten metal to follow. In addition, lost foam casting can be used to create complex shapes that would be difficult or impossible to produce with other methods.


The lost foam casting process is a type of casting that uses a foam pattern to create metal parts. The foam pattern is surrounded by sand and held in place by a box or mold. The molten metal is then poured into the mold, where it displaces the foam and takes on its shape.
