PET preform molding to refer to the process of making a final plastic product of a polymer made by a synthetic resin manufacturer. Processing methods (referred to as one-time processing of plastics) includes compression molding (molding) extrusion (extrusion molding) injection molding (injection molding) to blow molding (hollow molding) calendering and the like.
The operation can be automated, and the injection molding is also called injection molding. Injection molding is the use of an injection molding machine (or injection machine) to inject a thermoplastic melt into a mold under high pressure in cool and solidify the product. Injection molding can also be used to form thermoset plastics and foams. The strength of injection molding is fast production speed and high efficiency. It can form parts in disordered shapes and is especially suitable for mass production. The disadvantage is the high cost of equipment and molds and the difficulty in finishing the injection molding machine.
After years of operation research, Jilian Plastics has summed up the successful experience and shared it with everyone: it is then peeled off from the calender roll. The calendering is after the resin is mixed with various additives (kneading, filtering, etc.) and then passed through the calendar. The voids of two or more oppositely rolling rolls are processed into a film or sheet. A molding method that is cool and shaped.
