Other Processes

Permanent mold casting is a metal casting process that uses reusable molds (“permanent molds”) usually made from metal.

Permanent mold casting is offered to supplement other casting processes at Impro, such as investment casting and shell mold casting processes, to satisfy aerospace customers’ needs for precision aluminum castings. We carefully chose the appropriate casting process that provides the best quality and cost solutions. Impro permanent mold process pours aerospace aluminum castings up to 16 inches in diameter or length and weighing up to 35 pounds. Both gravity and counter-gravity pouring methods are used. Typical products include gear housings, pipe fittings, adapter ports, fuel injection housings, pump housing, front housing, pump covers, and flange mounting.
