The robot of the injection molding machine is an automated production equipment that can imitate some of the functions of the upper limbs of the human body, and can automatically control it to deliver products or control tools according to predetermined requirements for production operations. China's plastic processing plants in the coastal areas of South China and East China are showing increasing interest in robots, but the penetration rate of injection molding machine robots in the domestic press industry is less than 10%. The manipulator can ensure consistency of operation cycle, improve quality, and be more secure. With the rapid development of the plastics processing industry in China, the degree of automation in injection molding equipment is also increasing. Modern plastic injection molding machines are often equipped with robots to increase production efficiency. The number of China's export and import injection molding machines is basically the same, with around 15,000 units, but the import value is 920 million US dollars and the export value is 350 million US dollars.
Large plastic injection molding machines are mainly foreign brands, biaxially oriented PET in extrusion equipment, film units, and precision medical tube extrusion units have always been the domain of foreign companies. It is necessary to develop domestic 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 plastics machinery. Traditional plastic machinery also has certain potential in terms of energy saving. The reason is that previous designs often focused on single-machine production capacity. In the design of energy-saving plastic machinery, the production speed is not the most important indicator. The most important indicator is the energy consumption of processing unit weight products. Therefore, it is necessary to optimize the design based on the minimum energy consumption for the mechanical structure, control mode, and operating process conditions of the equipment.
