The mold is comprised of two halves that, when mated together, form a cavity into which the molten metal is poured. If an internal cavity is required in the casting, a core is placed inside the mold cavity. In sand casting process, after the metal solidifies, the mold is broken, the cores removed, and the part is readied for finishing operations.
