Injection Molding Machine Industry Development


The injection molding machine manipulator is an automated production equipment that can mimic some functions of the upper limbs of the human body and can be automatically controlled to transport the products or operate the tools according to predetermined requirements. Chinese plastics processing plants in the coastal areas of South China and East China have shown increasing interest in robots, but the penetration rate of injection molding machine manipulators in the domestic plastics industry is less than 10%. The robot ensures consistency in the cycle, improves quality and is safer. With the rapid development of the plastics processing industry in China, the degree of automation of injection molding equipment is also increasing. Modern injection molding machines are often equipped with robots to increase production efficiency. The number of export and imported injection molding machines in China is basically the same, both of which are about 15,000 units, but the import value is 920 million US dollars and the export value is 350 million US dollars. Precision injection molding machines are mainly foreign brands. Biaxially stretched PET in extrusion equipment, membrane units, precision medical catheter extrusion units, etc. have also been the domain of foreign companies. It is necessary to develop domestically produced precision injection molding and extrusion equipment with independent intellectual property rights. On the one hand, it can replace imports, and it can also make China occupy a place in the high-end market of international plastic machinery. Traditional plastic machinery also has certain potential in terms of energy saving, because the previous designs often only focus on the production capacity of a single machine. In the design of energy-saving plastic machinery, production speed is not the most important indicator, the most important indicator is the energy consumption of processing unit weight products. Therefore, the mechanical structure, control mode, and operating process conditions of the equipment must be optimized based on minimum energy consumption.

As energy conservation and consumption reduction have risen to national strategies, the problem of energy saving in injection molding machines has also been widely concerned. The energy saving in the field of conventional injection molding machines has two mature methods of inverter and servo motor, and servo motors are more and more widely accepted.

The servo energy-saving series injection molding machine is equipped with a high-performance servo variable speed power control system. During the molding process of the injection molding machine, different frequency output is made for different pressure flow, and the closed flow control of the pressure flow is performed accurately to realize the injection molding of the servo motor. High-speed response and optimal matching and automatic adjustment of machine energy requirements.
