Custom lost foam castings could be made by according to the drawings and requirements with quick production and competitive prices. Lost foam casting is a near-net forming process, suitable for the production of more precise castings of various sizes with complex structures and unlimited alloys, especially for large and thick-wall castings.

During lost foam casting process, the sand is not bonded and a foam pattern is used to form the shape of the desired metal parts. The foam pattern is "invested" into the sand at the Fill & Compact process station allowing the sand into all voids and supporting the foam patterns external form. The sand is introduced into the flask containing the casting cluster and compacted to ensure all voids and sapes are supported.
