Mold (m, Raúl j ù), industrial production for injection molding, blow molding, extrusion, die casting or forging molding, metallurgy, stamping and other methods to get the desired product of a variety of molds and tools. In short, the mold is used to molded items tool, this tool consists of a variety of parts, different from different parts of the mould.

Under external force to make stock a particular shape and size of the workpiece. Widely used in stamping, forging, cold heading, extrusion, pressing, die casting, powder metallurgy parts, plastics, rubber, ceramics and other products, compression moulding or injection process.

Internal shape can obtain the appropriate dimensional shape of the billet. Molds generally consist of moving half and fixed (or punch and die) in two parts, can be divided into the two can be combined. Separate out parts, closing the billets into the mold cavity.
