With the improvement of the level of CNC machining equipment, companies have increased the development of plastic molds, plastic molds have become the most attractive “cheese” in the mold varieties. In recent years, the development of plastic molds in China has been 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 total molds will gradually increase, and the development speed will be faster than other molds.
An injection mold is a part that imparts shape and size to a plastic during molding. Although the structure of the mold may vary depending on the type and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is uniform. The mold is mainly composed of a casting system, a molded part and a structural part. The gating system and the molded part are in direct contact with the plastic and vary with the plastic and the product. It is the most complicated and most varied part of the mold, and requires the highest degree of smoothness 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 channel, the cold material hole, the split channel and the gate. Molded parts refer to various parts that make up the shape of the product, including moving molds, fixed molds and cavities, cores, forming rods, and exhaust ports.
The plastic products produced by the injection molding processing method greatly satisfy the needs of people for production and life. The plastic parts produced by the injection molding method are fast and the size is relatively accurate. Most of the plastic products are currently injection molding methods. Production, which also makes China’s injection molding industry a leap-forward development.
The continuous improvement of plastic properties has also led to the plastic accessories gradually entering 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 the plastic parts produced by plastic injection molding processing methods. However, with the development of the times, there are various problems in the injection molding industry in China. In the future, we must not only solve these problems but also clarify the future development direction.
The common problems in the injection mold processing industry include: simple OEM production methods, backward machinery and equipment, insufficient investment in R&D, and backward production management. The requirements for injection molding products in the market are definitely higher and higher. It is an injection molded product used in fields such as automobiles and home appliances.
Therefore, the development of the future injection molding industry must break the existing production methods. In order to obtain greater profits, it must be changed from OEM to ODM. It must be developed from simple injection molding to precision injection molding. It must be from simple plastic injection molding. The development of engineering plastic injection molding processing must be developed from extensive development to energy conservation and environmental protection. Only by grasping these big development directions in the future, China’s injection mold processing industry can stand in the world injection molding industry.
