depends on the molding material:
metal mold, plastic mold, special mold.
metal dies are divided into: including stamping dies (such as blanking dies, bending dies, deep drawing dies, turning dies, shrinkage dies, undulating dies, bulging dies, plastic dies, etc.), forging dies (such as die forging dies, upsetting dies, etc.), extrusion dies, extrusion dies, die casting dies, forging dies, etc.;
non-metal dies are divided: plastic molds, inorganic non-metallic molds, sand molds, vacuum molds and paraffin molds.
Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic molds can generally be divided into: injection molds, extrusion molds, gas-assisted molding molds, etc.
