PET plastic molds are essential tools for producing PET plastic products. In terms of material, they are typically made of high-quality mold steel, which possesses high strength, high hardness, and good wear resistance, ensuring the mold is not easily damaged during long-term use.
Structure-wise, they generally consist of two parts: a fixed mold and a moving mold. The fixed mold is mounted on the fixed platen of the injection molding machine, while the moving mold is mounted on the moving platen. The molding and demolding of the plastic product are achieved through the opening and closing action of the injection molding machine. Functionally, PET plastic molds can precisely shape PET products of various shapes and sizes to meet the needs of different industries. Their technical characteristics are reflected in high-precision machining processes; the mold cavity and core have low surface roughness and high dimensional accuracy, ensuring the appearance quality and dimensional accuracy of the finished product.
In terms of specifications, different sizes are designed according to the size and shape of the product to be produced, commonly including small, medium, and large sizes. In terms of manufacturing processes, they undergo multiple processes such as forging, machining, heat treatment, and surface treatment. Surface treatment, in particular, improves the mold's corrosion resistance and demolding performance, extending its service life. In conclusion, PET plastic molds, with their excellent performance and sophisticated craftsmanship, have become an indispensable key piece of equipment in the production of PET products.
