Permanent Mold Casting
Permanent Mold castings is a metal casting process that uses a reusable mold that is usually made from metal. Most commonly, gravity is used to fill the mold, however gas pressure or a vacuum are also used. With this process, the reusable mold allows for good surface finish, dimensional accuracy and high production rates.
Common materials used for this process include, aluminum alloys, and zinc. Iron and Steel alloys can be cast using a graphite mold.
