Description

Pattern is covered in a ceramic slurry, then burned out after the slurry dries. Molten metal is poured and the mold broken.

Common Materials

Most ferrous and nonferrous metals- Carbon, tool, and stainless steel. Aluminum, magnesium, copper based alloys.

Advantages

Great surface finish and no parting line, can be used for complex designs can include undercuts, can make parts a machine (mill or lathe) can't.

Description

Molten metal is poured into a reusable, permanent mold, using gravity to fill the mold cavity.

Common Materials

Aluminum, magnesium, copper alloys and zinc alloys. If a graphite mold is used, iron and steel can be cast this way.

Advantages

Smooth surface finish, good dimentional accuracy, fast production time, can make parts with internal pockets using sand core inserts, low scrap rate.

Description

Sand is packed around a reusable pattern to create a mold. Molten metal is poured and the mold is broken to remove the part when cool.

Common Materials

Iron, brass, bronze aluminum alloys.

Advantages

Least expensive option for small volume production, can be used to make large parts, low post-casting tool cost, sand is reusable.
