Product design should be broad, the future is also great, and the requirements for their own knowledge should be broad. Product design is to design a product, and mold design is to design a tool for manufacturing products. This tool is called mold.

Mold is an industrial product that shapes materials into specific structural forms in a certain way, and it is also a production tool that can mass-produce industrial product parts with certain shape and size requirements. Almost all industrial products, from airplanes and cars to teacups and nails, have to be molded with molds. The high precision, high consistency and high productivity of parts produced by mould are incomparable with any other processing method. Mould largely determines the quality, benefit and new product development ability of products. Therefore, the mold has the honorary title of "Mother of Industry".
