Injection molding machine in the process of development has been in constant improvement, it gradually to energy-saving equipment transformation. However, if the injection molding machine wants to keep the smooth development, there is still a lot to improve, because there is still a big gap between China's injection molding machine industry and the developed countries' injection molding machine industry, we need to find ways to narrow the gap.
 
 
 
Injection molding machine, also known as injection molding machine or injection machine. It is thermoplastic or thermosetting plastic plastic molding mold made of various shapes of plastic products main molding equipment. Divided into vertical, horizontal, electric. The injection molding machine heats the plastic, applying high pressure to the molten plastic, causing it to eject and fill the mold cavity.
 
 
 
The injection molding machine manipulator mimics some of the functions of the human upper limbs and can be automatically controlled to operate the equipment in accordance with the regular delivery of products or for the production of automated production tools. China's plastic processing plants in southern and eastern coastal regions are increasingly interested in robots, but injection molding machines are less than 10 per cent popular in the country. Robots ensure consistent operation cycles, improve quality, and are safer. With the rapid development of plastic processing industry in China, injection molding equipment is becoming more and more automated. Modern injection molding machines are often equipped with robots to improve production efficiency. The number of injection molding machines imported and exported in China was about the same, about 15,000, but the value of imports was $920 million and exports $350 million. Precision injection molding machine is mainly foreign brands, extrusion equipment in two-way stretch PET, membrane unit, precision medical catheter extrusion unit has also been the territory of foreign companies. It is necessary to develop the independent intellectual property rights of the domestic precision injection molding and extrusion equipment. On the one hand, it can replace imports, and also give China a place in the international high-end plastic machinery market. Traditional plastic machinery also has some potential in terms of energy conservation, because the previous design often only focused on independent production capacity. In the design of energy-saving plastic machinery, the production speed is not the most important index, the most important index is the energy consumption weight of the processing unit. Therefore, it is necessary to optimize the mechanical structure design, control mode and operating conditions of the equipment according to the minimum energy consumption.
 
 
 
With the increase of national energy saving strategy, energy saving injection molding machine is also widely concerned. The traditional injection molding machine is used in the field of energy-saving motor and frequency conversion motor.
 
 
 
Servo energy-saving series injection molding machine, equipped with high-performance servo variable speed power control system, in the injection process for different pressure flow, make different frequency output and pressure flow accurate closed-loop control to achieve servo motor injection high-speed response and best matching and automatic adjustment of energy requirements.
 
 
 
1. Adopt servo controller, servo motor and other energy-saving devices with excellent performance.
 
 
 
2. Sensitive servo control system, quick start-up response time of 0.04S.
 
 
 
3. The closed-loop control composed of servo motor and hydraulic system is greatly improved compared with the traditional repeat precision model.
 
 
 
4. Reduce the impact of unlocking mold and extend the service life of mechanical parts and molds.
 
 
 
5, reduce the use of electricity, under ideal working conditions, the machine than the traditional injection molding machine energy efficiency up to 20% - 80%
 
 
 
6, the heat of the system is much lower than the traditional injection molding machine, saving about 30% of the cooling water, and extending the service life of oil seals and hydraulic parts.
 
 
 
7. Lower noise during operation than traditional injection molding machine.
 
 
 
If you want to give full play to the injection molding machine its performance advantages, in the use of the process also need a lot of attention, be sure to follow the correct method to operate, to avoid some of the intentional occurrence.
