According to the structural characteristics, the mold manufacturing is divided into a flat punching die and a cavity die having a space. The punching die utilizes the precise fit of the punch and the die, and some even have no clearance fit. Other forging dies such as cold extrusion dies, die casting dies, powder metallurgy dies, plastic dies, rubber dies, etc. are all cavity molds for forming three-dimensional shaped workpieces. The cavity mold has dimensional requirements in three directions of length, width and height, and the shape is complicated and manufacturing is difficult. Mold production is generally one-piece, small batch production, manufacturing requirements are strict and precise, and more sophisticated processing equipment and measuring devices are used.
