Permanent mold is a metal casting process that employs reusable molds. General advantages of permanent mold are consistent surface finish, and consistent dimensional accuracy. Tooling is typically more costly than sand cast tooling, but produces a lower piece price.
Setting a sand core into a sand mold
A core is a shaped body, usually made of sand, which forms the interior part of the casting. In metalcasting, the mold provides a space for the molten metal to go, while the core keeps the metal from filling the entire space. This video features the placement of a sand core in a sand casting at Alcast Co. Midwest Works.
