PET Injection Molding material selection: a wide range of options that precisely match your needs

In the process of material selection, we will make precise selections according to the specific use of the product. For the field of food packaging, we give preference to food-grade PET materials, which have passed strict safety tests, are non-toxic and tasteless, can effectively ensure food safety, and have good gas barrier properties to extend the shelf life of food. In the production of beverage bottles, we use PET special materials with high transparency and high barrier to ensure that the beverage is not affected by external oxygen and moisture during storage, and maintains its flavor and quality. In addition, there are specially modified PET materials, such as reinforced PET, which further improves the strength and rigidity of the product by adding reinforcing materials such as glass fiber, and is suitable for manufacturing mechanical parts and other products with high mechanical property requirements; Flame-retardant PET meets the needs of fire safety in the fields of electrical and electronics.

PET Injection Molding Production Process: Rigorous and Efficient Standardized Process

Our PET injection molding production process follows a rigorous, standardized process. The first is mold design and manufacturing, according to the three-dimensional model of the product, the use of advanced design software for precision design, and through high-precision processing equipment to manufacture molds, to ensure that the dimensional accuracy and surface quality of the mold to meet high standards. The PET raw material is then pre-treated, and since the PET material is highly hygroscopic, we will dry it sufficiently to remove moisture and prevent defects such as bubbles and silver wires from appearing during the molding process. Then enter the injection molding process, the dried PET raw materials are fed into the barrel of the injection molding machine, heated to a molten state, quickly injected into the mold cavity under high pressure, fully filled with the product after pressure holding, and then quickly cooled and shaped through the cooling system. Finally, post-processing, including gate removal, burr removal, necessary trimming and quality inspection of the product, to ensure that each product meets the quality requirements.

PET Injection Molding Surface Treatment: A wide range of solutions to improve appearance and function

We have mastered the surface treatment technology of a wide range of PET injection molded products to meet different appearance and functional needs. In order to enhance the surface gloss and aesthetics of the product, we will use polishing treatment, through mechanical polishing or chemical polishing, so that the surface of the product can achieve a mirror effect. The spraying process can give the product a rich color and special texture, while improving the wear and weather resistance of the product. Screen printing and hot stamping technology can add beautiful text, patterns and logos to the surface of the product, enhancing the brand recognition of the product. In addition, for some products that require special functions, we will also carry out coating treatment, such as aluminized film to enhance the barrier performance of the product, suitable for food and pharmaceutical packaging; The anti-wear film can improve the scratch resistance of the product surface and prolong the service life of the product.

PET Injection Molding Dimensional Inspection: Strict and precise quality control system

In terms of dimensional inspection, we have established a strict and precise quality control system. We first use conventional measuring tools such as calipers and micrometers to make preliminary measurements of the key dimensions of the product, and quickly screen out products that obviously do not meet the requirements. For products with high precision requirements, we use a coordinate measuring instrument for accurate measurement, which can detect the product in an all-round way in three-dimensional space, and accurately obtain the dimensional deviation, shape and position tolerance of the product. At the same time, we also use optical inspection equipment to quickly detect and compare the appearance and size of products through image recognition technology, and find small size differences and defects in time. Through the comprehensive use of a variety of testing methods, we ensure that the dimensional accuracy of each product can meet the design requirements, providing a reliable guarantee for product quality.

PET Injection Molding Product Applications: Extensive and in-depth multi-field coverage

PET injection molded products are used in a wide range of applications in our lives and production. In the field of food and beverage packaging, PET bottles have become the main packaging containers for carbonated drinks, fruit juices, mineral water and other beverages due to their high transparency, good barrier and lightness; At the same time, PET boxes and PET trays are also widely used in food packaging to ensure the freshness and safety of food. In the field of electronic appliances, PET material is used in the manufacture of mobile phone shells, computer accessories, etc., and its good insulation and mechanical properties meet the needs of electronic products. In the field of medical devices, PET is used in the manufacture of syringes, infusion set parts, etc., and its non-toxic and chemically stable characteristics meet the strict requirements of the medical industry. In addition, PET injection molded products can also be found in toys, stationery, automotive interiors and other industries, and its excellent performance and diverse properties make it ideal for many industries.
