A
foundry is a
factory that produces
metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal in a mold, and removing the mold material or casting after the metal has solidified as it cools. The most common metals processed are
aluminium and
cast iron. However, other metals, such as
bronze,
brass,
steel,
magnesium, and
zinc, are also used to produce castings in foundries. In this process, parts of desired shapes and sizes can be formed.
