What is a mold?

Mu JU, industrial production for injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods to obtain the required products of various molds and tools. In short, a mold is a tool used to make a molded article. The tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material. Known as the "mother of industry" title.

A tool for turning a blank into a piece of specified shape and size under external forces. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as engineering plastics, rubber, ceramics and other products of pressure molding or injection molding forming processing. The mold has a specific outline or cavity shape, and the blank can be separated (blanked) according to the outline shape by applying the outline shape with a cutting edge. The shape of the blank can be obtained by using the shape of the inner cavity. The mold generally includes moving mold and fixed mold (or punch and die) two parts, the two can be divided and combined. Take out the parts when separate, and inject the blank into the mold cavity when close. Mold is a precision tool with complex shape, bearing billet expansion force, and has higher requirements on structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important marks of mechanical manufacturing level.
