With the improvement of CNC processing equipment, enterprises have increased their efforts to develop plastic molds. Plastic molds have become the most attractive “cheese” among mold varieties. In recent years, the development speed of China’s plastic molds is quite fast. At present, plastic molds account for about 30% of the entire mold industry. With the rapid development of China’s automobiles, home appliances, electronic communications, and various building materials, it is expected that in the future mold market, the proportion of plastic molds in the total mold will still gradually increase, and the development speed will be faster than other molds.
Injection molds are parts that give plastics shape and size during molding. Although the structure of the mold may vary due to the variety and performance of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is consistent. The mold is mainly composed of three parts: pouring system, molding parts and structural parts. Among them, the pouring system and the molded parts are the parts that are in direct contact with the plastic and change with the plastic and the product. They are the most complicated and the most varied parts in the mold, and require the highest processing finish and precision.
The pouring system refers to the part of the flow path before the plastic enters the cavity from the nozzle, including the main flow path, the cold cavity, the flow path and the gate. Molded parts refer to various parts that form the shape of the product, including moving mold, fixed mold and cavity, core, molding rod and exhaust port.
The plastic products produced by the injection molding method greatly meet people’s needs for production and life. Because the plastic parts produced by the injection molding method are fast and the size is relatively accurate, etc. At present, most plastic products are produced by the injection molding method The production, which also makes China’s injection molding processing industry has been leaping development.
The continuous improvement of plastic performance has also made plastic accessories gradually enter various industries. At present, the demand for plastic products in the fields of building materials, automobiles, home appliances, and electronics is still relatively strong. The rapid development of these industries has also made the development of China’s plastic products industry into a rapid development stage, especially plastic parts produced by plastic injection molding methods. However, with the development of the times, various problems have appeared in China’s injection molding processing industry. In the future, not only should these problems be solved, but also the future development direction must be clarified.
Taken together, the common problems in the injection mold processing industry are: simple OEM production methods, backward machinery and equipment, insufficient investment in research and development, backward production management, etc.! The future market demand for injection molded products is definitely higher and higher, especially It is an injection molded product used in fields such as automobiles and home appliances.
Therefore, the future development of the injection molding processing industry must break the existing production methods. To obtain greater profits, it must change from OEM to ODM. It must develop from simple injection molding to precision injection molding processing. It must move from simple plastic injection molding. The development of engineering plastic injection processing must be developed from extensive development to energy saving and environmental protection. Only by grasping these major development directions in the future can China’s injection mold processing industry stand a foothold in the world’s injection molding industry.
