Casting (metalworking) - Wikipedia

In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.The metal is poured into the mold through a hollow channel called a sprue.The metal and mold are then cooled, and the metal part (the casting) is extracted.
