Mold Definition and Classification

Mold is called “Mother of Industry”. It is a processing tool that processes raw materials and gives raw materials a complete configuration and precise size. It is mainly used for efficient and high-volume production of related parts in industrial products. The development of the mold industry has always been valued by the state. According to the National Development and Reform Commission's Catalogue of Industrial Structure Adjustment (2011), “Precision molds (punch mold accuracy ≤0.02 mm, cavity mold accuracy ≤0.05 mm)” are listed as encouragement industry, and give priority to development. With the development of modern industry, molds have been widely used in automobiles, home appliances, consumer electronics, instrumentation, aerospace and medical devices, and about 60%-80% of parts and components need to be molded by mold. According to statistics, the proportion of molds that can drive related industries is about 1:100, it means that the development of molds is 100 million yuan, which would drive 10 billion yuan of related industries. According to different molding materials, the mold can be divided into metal forming mold, plastic forming mold and other forming molds. For the different molding methods, the mold can be divided into injection mold, stamping mold, die-casting mold and forging die; And for different processing precision, the mold can be divided into ordinary precision molds and precision molds.
