Summary: 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.. Casting is often used for creating one or more copies of an original piece of sculptural (three-dimensional) artwork. It is also used …

into a specially-designed box (flask) and compress special molding sand around it on all sides. The sand takes the shape of the pattern, the pattern is removed from the mold (usually the mold is made in multiple parts to accommodate this), and the metal is poured in. The mold is destroyed in extracting the casting, but the sand can be reused.
