The key points of purchasing an injection molding machine are to have a high degree of automation, complete functions, and high production efficiency. Modern injection molding machines can be operated manually, semi-automatically and fully automatically. As long as the mold design is reasonable, the fully automatic operation from injection molding to ejection and dropping of the product can be realized , and it can also be equipped with a manipulator for unmanned operation. The insert core function, hydraulic nozzle control function and fast heating runner probe function can all be programmed into the automatic program in the injection molding cycle for automatic circulation. High production efficiency is mainly manifested in the short molding cycle of each molded product under normal injection molding process conditions. This reflects the comprehensive performance indicators of the mechanical, electrical, and hydraulic systems of an injection molding machine. Therefore, high-quality hydraulic and electronic components and sophisticated manufacturing techniques must be used to improve the sensitivity and repeatability of the injection molding machine system. The efficient operation of the injection molding system is a reliable guarantee.
