Definition Casting is a process by which a
material is introduced into a mold while it is
liquid, allowed to solidify in the shape inside
the mold, and then removed producing a fabricated
object, part, or casing. Molding is the process
of manufacturing by shaping pliable raw material
using a rigid frame or model called a mold.
