In short, the mold is a tool used to make molded objects. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. The mold that can apply pressure to the metal blank from the vertical and horizontal (or inclined) directions separately or simultaneously so that the blank can be formed in multiple directions is a multi-directional forging die.
