This step in the lost foam metal casting process involves the removal of the remaining sand and surface paint on the casting. The feeds and risers are then removed, leaving behind the cast and completing the lost foam casting process. These lost foamed parts can undergo further finishing processes such as heat treatment f required.

The lost foam casting process is similar to investment casting, except foam is used for the pattern instead of wax. This process simplifies the investment casting process by removing the need to melt the wax out of the mold because polymer foams have a lower boiling point. Sinoway has developed the lost foam casting process for more than ten years.

2022-2-10 · Lost Foam Casting. Lost foam casting is a process used to create complex metal pieces and parts in which molten metal evaporates a foam mold being held still with sand. The process starts with a polystyrene foam as the mold material which can be carved, machined from a foam block, or created using a process similar to injection molding.
