Briefly describe the development trend of hot runner technology for injection molds
Hot runner technology, with its unique technical advantages such as cost saving and shortening of molding cycle, has become an important direction for the development of plastic injection molding process. In Europe and the United States, most of the injection molding production relies on hot runner technology, but in China, there are very few companies that adopt this advanced technology. However, with the further development of China's mold industry, this technology will be gradually promoted and widely used. As an innovative technology for injection molds, hot runner technology has many advantages, and its use range is more and more extensive, representing one of the development directions of injection molds. In recent years, with the development of the mold industry and the improvement of market requirements, hot runner technology is also constantly developing and perfecting, and its development trend is mainly reflected in the following aspects. Miniaturization of components The miniaturization of components is one of the main directions for the development of injection molds in the future, and precision injection molding can be achieved well. The hot runner mold shrinks the nozzle, which can realize multi-cavity or multi-gate filling, thereby improving the use efficiency. Since the 1990s, many companies have used component miniaturization to successfully develop combined multiple nozzles or multi-gate nozzles. Standardization of components The structure of the hot runner mold is complicated and the cost is high! Standardization of components can effectively improve the life cycle of components, reduce costs, and facilitate component maintenance. The most important point is that it is more conducive to the popularization and application of hot runner technology. At the same time, computer-aided technology can be used to confirm the mold design and improve the standardization of components. Accuracy of temperature control The quality of plastic parts is largely related to the temperature during the injection molding process. The key technology of hot runner mold injection molding is the control of the temperature of the runners and gates. Therefore, various technologies such as heat pipe technology can be combined to improve the accuracy of the temperature control device, so that the parts are more evenly heated, so that the quality of the plastic product can be better improved. Extensive use Since hot runner technology has the advantages of saving resources, improving production efficiency, and improving product quality, improving its use range is its main development direction in the future. To this end, combined with its development status and other injection molding technology, it is required to develop new molding processes, such as multi-color co-injection, laminated hot runner injection molding, etc., to meet the requirements of more materials, enhance the practicality of hot runner technology, hot runner The technology has been used in injection molds for decades. Due to its unparalleled advantages such as high product quality, low energy consumption, short molding cycle, high automation and wide application range, the development speed is very fast. Many countries have been promoted and applied. China has also achieved many results in the research of hot runner technology. At the same time, due to the immature key technologies, the lack of standardized production of raw materials, the research and development of hot runner technology in China is still in its infancy, and its penetration rate is still relatively low! I believe that with the development of China's injection molding industry, hot runners will be faster in China. The speed of development applications.
