China's famous injection molding machine experts, Haitian Group's general technical advisor and professor Wang Xingtian of Beijing University of Chemical Technology recently stated: “Energy saving and consumption reduction has become the most important development trend of injection molding machines. All-electric, two-plate injection molding machines will become the mainstream of the market in the future.â€
The annual growth rate of China's plastics machinery industry in recent years is about 30%, which is one of the fastest growing industries in China's machinery industry. As the largest variety of injection molding machine, the annual output accounts for about 35% of the total output of the presses and accounts for about 60.4% of the total volume of exported presses in the country. With the increasingly fierce competition in plastic products, energy-saving injection molding machine has become the mainstream market. "All-electric and two-plate injection molding machines are very energy-saving and consume less, are in line with national industrial policies, and have now become popular in foreign countries. I believe this is a development trend," said Wang Xingtian.
Compared with traditional hydraulic injection molding machines, all-electric injection molding machines are cleaner because they do not use hydraulic oil, which also means that there is no need for cooling, so there are no costs incurred for the purchase, operation, and maintenance of cooling lines, and at the same time, energy consumption can be reduced. Up to 30% to 50%, and stable operation, high repeatability, especially for precision injection molding. In Japan and European and American markets, all-electric injection molding machine technology has been used on a large scale. In the new domestic projects, the model has also been recognized as the focus of the development of presses. All-electric injection molding machine control system is very complex, the current leading domestic injection molding machine companies - Haitian Group has introduced such products to the market, filling the domestic gap.
At present, China's injection molding machines are still dominated by the three-plate type. In developed countries in Europe and America, the compact two-platen injection molding machine has become the mainstream of the market and has gained wider application in new construction projects. The two-platen machine has reduced one template compared to the three-platen machine, so the cost is lower, the opening and closing mode cycle is shorter, and the efficiency is higher. However, the structure of the piston in the cylinder of this type of engine is complicated, and the hydraulic valve cannot be installed when the piston of the fuel cylinder is small. Therefore, the medium and small-sized machines cannot be used, and they are generally applicable to larger models. Wang Xingtian pointed out: “Two-board machines are the main stream for the development of mainframes. Accelerating the development of these types of models is a topic that domestic companies should focus on.†The good news is that domestic companies such as Donghua and Haitian have been developing and producing two-platen machines. , And some products have been successfully developed, which will bring China's large-scale injection molding machine design and manufacturing to a new level.
