PET screw barrel is a key component for injection molding machines, mainly used for processing PET (polyethylene terephthalate) materials. PET is a commonly used plastic raw material with excellent transparency, heat resistance and mechanical properties. It is widely used in food packaging, beverage bottles, fibers and other fields. PET screw barrels are usually made of high-strength alloy steel materials, and undergo precise processing and heat treatment processes to ensure that they have good wear resistance and corrosion resistance. The structural design of PET screw barrels is very important, generally including screws, barrels, heating sleeves and other components. Whether the design is reasonable directly affects the quality and efficiency of injection molding. PET screw barrels have the following characteristics: 1. High precision: The surface of PET screw barrels is specially treated to ensure uniform heating and compression of plastic particles, and improve the precision and surface quality of molded products. 2. High wear resistance: PET material has poor fluidity and is prone to wear of the screw barrel. Therefore, PET screw barrels are usually made of wear-resistant alloy materials to extend their service life. 3. High efficiency: The PET screw barrel is reasonably designed to improve production efficiency, reduce energy consumption, and save production costs. 4. Corrosion resistance: PET materials are easily decomposed at high temperatures to produce harmful gases, so the PET screw barrel needs to have good corrosion resistance to ensure a safe production environment. In general, the PET screw barrel is a vital component in the injection molding machine, and its quality and performance directly affect the quality and production efficiency of the product.
