[0002] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidification, obtaining the molded product. After the injection mold is used, its interior needs to be cleaned for the next use, which requires the use of cleaning equipment.
