Future development trend and prospect of China's injection molding machine industry

Release time:


The injection molding machine has been constantly improving in the process of development, and it is gradually transforming to energy-saving equipment. However, if the injection molding machine is to continue to develop smoothly, there is still much to be improved. Because there is still a big gap between the injection molding machine industry in China and that in developed countries, we need to find ways to narrow these gaps.
Injection molding machine is also known as injection molding machine or injection molding machine. It is the main molding equipment for making thermoplastic or thermosetting plastics into plastic products of various shapes using plastic molding molds. It is divided into vertical type, horizontal type and all electric type. The injection molding machine heats the plastic and applies high pressure to the molten plastic to make it eject and fill the mold cavity.
The manipulator of the injection molding machine can imitate some functions of the human upper limbs, and can be automatically controlled to make it operate the equipment according to the regular delivery of products or the tools used for automatic production. Chinese plastic processing plants in South China and East China coastal areas are increasingly interested in robots, but the penetration rate of injection molding machine robots in China is less than 10%. The robot can ensure the consistency of the operation cycle, improve the quality, and be safer. With the rapid development of plastic processing industry in China, the degree of automation of injection molding equipment is becoming higher and higher. Modern injection molding machines are usually equipped with robots to improve production efficiency. China's import and export of injection molding machines are basically the same, about 15000 sets, but the import amount is 920 million dollars, and the export amount is 350 million dollars. Precision injection molding machines are mainly foreign brands. Extrusion equipment in biaxial stretch PET, membrane unit, and precision medical catheter extrusion unit have also become the territory of foreign companies. It is necessary to develop independent intellectual property rights of domestic precision injection molding and extrusion equipment. On the one hand, it can replace imports, and also enable China to occupy a place in the international high-end plastic machinery market. Traditional plastic machinery also has certain potential in energy saving, because previous designs often only focus on independent production capacity. In the design of energy-saving plastic machinery, the production speed is not the most important indicator, but the most important indicator 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 strategic energy conservation, energy-saving injection molding machines are also widely concerned. The traditional injection molding machine is used in the field of energy-saving motor and frequency conversion motor, in which the servo motor is more and more widely accepted.
The servo energy-saving injection molding machine is equipped with a high-performance servo variable speed power control system. During the injection molding process, the servo motor can inject high-speed response and the demand for optimal matching and automatic adjustment of energy for different pressure flows, so that different frequency outputs and accurate closed-loop control of pressure flows can be achieved.
1. Adopt energy-saving devices such as servo controller and servo motor with excellent performance.
2. Sensitive servo control system, quick start response time 0.04s.
3. The closed loop control composed of servo motor and hydraulic system is greatly improved compared with the traditional repetitive precision model.
4. Reduce the impact of unlocking the mold, and extend the service life of mechanical parts and molds.
5. Reduce the use of electricity. Under ideal working conditions, the energy efficiency of the machine is 20% - 80% higher than that of traditional injection molding machines
6. The system heat is far 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. The noise of the whole line is lower than that of the traditional injection molding machine
If you want the injection molding machine to give full play to its performance advantages, you need to pay more attention in the process of use. You must operate it in the correct way to avoid some intentional occurrence.
