In short, molds are tools used to make molded objects. This tool is composed of various parts, and 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. Known as the "mother of industry", it is a tool that makes the blank into a part with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The workpiece formed by the mold requires a specific mold, which is manufactured manually through CNC machine tools. The processed mold needs special workers to measure.
