Structure of plastic molds

Although it may vary greatly due to different types and properties of plastics, shapes and structures of plastic products, and types of injection machines, the basic structure remains the same. The mold is mainly composed of a pouring system, a temperature control system, molded parts, and structural parts. The pouring system and molded parts are the parts that come into direct contact with the plastic and vary with the plastic and the product. They are the most complex and variable parts in the mold, requiring the highest processing smoothness and accuracy.
The pouring system refers to the part of the flow channel where plastic enters the mold cavity from the nozzle, including the main flow channel, cold material cavity, diversion channel, and sprue. Formed parts refer to various components that make up the shape of a product, including moving molds, fixed molds, cavities, cores, forming rods, and exhaust ports.
Driven by high-tech and the demand for pillar industry applications, China's plastic molds have formed a huge industrial chain, from the upstream raw and auxiliary material industry and processing and testing equipment to the downstream application industries such as machinery, automobiles, motorcycles, home appliances, electronic communication, and building materials. The development of plastic molds is full of vitality.
