What Is Permanent Mold Casting?

Permanent mold casting is a metal casting process that uses reusable molds (so-called "permanent molds", typically made of metal). Gravity filling of the mold is the most common method, called gravity casting, but there are also processes that use air pressure or vacuum. There is another variation of gravity casting, called leaching, to produce hollow castings. Commonly used casting metals include aluminum, magnesium and copper alloys. Other materials such as tin, zinc, and lead alloys, as well as steel and iron, are also cast using graphite molds.
Typical parts include gears, bolt grooves, wheels, gearboxes, pipe fittings, fuel injection system housings, and vehicle engine pistons.
