The permanent mold casting process is the production of castings by pouring molten metal into permanent metal molds under gravity pressure. Castings produced in permanent molds have finer grain structure and better strength properties than those cast from similar alloys in sandcasting and diecasting. The castings have better dimensional uniformity and in addition, a smooth surface finish is achieved right out of the mold, therefore, eliminating some secondary polishing operations.
