Permanent mold casting is metal casting process that employs reusable molds ("permanent molds"),usually made from metal. The most common process uses gravity to fill the mold,however gas pressure or a vacuum are also used. A variation on the typical gravity casting process,called slush casting,produces hollow castings. Common casting metals are aluminium,magnesium,and copper alloys. Other materials include tin,zinc,and lead alloys and iron and steel are also cast in graphite molds.
Typical parts include gears,splines,wheels,gear housings,pipe fittings,fuel injection housings,and automotive engine pistons.
