[0002] Mechanical processing refers to the process of changing the size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. In mechanical processing, molds are usually required. Molds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping, etc. 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. It is known as the "mother of industry".
