PET bottle forming refers to the process of making a final PET product from a polymer made by a synthetic resin factory. The processing method (referred to as one-time processing of PET) includes compression molding (molding) extrusion molding (extrusion molding) injection molding (injection molding) blow molding (hollow molding) rolling, and the like.

The operation can be automated, and the injection molding is also called injection molding. Injection molding is a method in which a thermoplastic PET melt is injected into a Pet Preform Mould under high pressure using an injection molding machine (or an injection machine) to obtain a product by cooling and solidifying. Injection molding can also be used for the formation of thermoset PET and foam PET. The advantage of injection molding is that it is fast and efficient. It can form parts with complex shapes, and is especially suitable for mass production. The disadvantage is that the equipment and mold cost is high, and the injection molding machine is difficult to clean.

PET beverage bottles can reach a maximum temperature of 121 degrees, but PET bottles have different shapes and high temperatures.

After years of homework research, the Pet Preforms manufacturer has shared the experience and shared it with you: it is then peeled off from the calender roll. The calendering is the two processes of the calender after the resin is processed (kneaded, filtered, etc.). The gap of one or more of the opposite rolling rolls is processed into a film or sheet. A molding method that is cooled and shaped. Calendering is mainly used for the molding of polyvinyl chloride resin, and can be used to make films, sheets, plates, artificial leather, floor tiles and other products.
