Plastic mold manufacturing refers to tools that are matched with plastic molding machines to give plastic products a complete structure and size. There are many types of plastics, and there are many processing methods, so plastic mold manufacturing is also diverse.

1. Injection mold, which is mainly used for designing and producing thermoplastic plastic parts. The most common type of molding mold that can be applied and researched in product production. The corresponding processing technology equipment for plastic injection mold is plastic injection molding machine. The plastic first heats the material at the bottom of the injection molding machine. The inside of the barrel is heated and melted, and then driven by the screw or plunger of the injection molding machine, the injection molding machine nozzle and the pouring operation system of the mold have entered the mold cavity, and the plastic is cooled and hardened to form, and the demolding method is improved.

2. Compression mold, a mold mainly used for forming thermosetting plastics, and its corresponding equipment is a pressure forming machine. The compression molding method heats the mold to the molding temperature (generally 103°-108°) according to the characteristics of the plastic, and then puts the measured compression molding powder into the mold cavity and the feeding chamber, and closes the mold. The plastic softens and viscous flows under the action of high temperature and high pressure. After a certain period of time, it is cured and formed into the desired product shape.

3. Extrusion mold is a kind of mold used to form continuous plastic products, also called extrusion mold, which is used in the processing of pipes, bars, monofilaments, plates, films, cable coatings, profiles, etc.
