The mold industry is a derivative manufacturing industry that serves the manufacturing industry. To put it bluntly, a mold is a model, a mold used to mass-produce products for manufacturers. Manufacturers need to quickly produce products according to this ready-made model. Molds have played an irreplaceable role in our lives. Most of our daily necessities are inseparable from molds, such as computers, telephones, fax machines, keyboards, cups, chairs, spoons and other plastic products. In addition, like automobiles, the outer covers of motorcycle engines are also made of molds. It takes more than 20,000 molds for a car bumper, car lights, grille, plastic parts, interior parts, etc. Modern life is inseparable from the support of the mold industry. As long as it is a product that needs to be mass-produced, it cannot be separated from the mold, at least in the last 50 years. How the mold is produced may not be very clear to most people except those in the mold industry.
