Analysis on the development trend of China's plastic machinery industry

China's plastic machinery began in the late 1950s. With the development of China's petrochemical industry, China's plastic machinery industry gradually formed an independent industrial sector, and began to take shape. Plastic machinery plays an important role in the production of plastics. Since the beginning of the 21st century, China's plastic machinery industry has achieved sustained and rapid development, and is one of the fastest growing industries in the country. The main economic indicators rank among the top in the national machinery industry. At present, there are 546 domestic plastic machinery manufacturers in China, and most of the injection molding machines are produced. The ten largest in the industry account for 39% of the total sales volume in the past five years, relying on technology promotion and competitive prices, we The manufacturers have established businesses that have successfully challenged Germany and Japan, Europe and the United States and other developed markets.
However, China is still an important importer of plastic machinery. As China's plastic machinery enterprises mainly produce low-end plastic machinery, many varieties of plastic machinery production technology is lacking, resulting in China's plastic machinery export prices are generally low, lack of international competitiveness. The price of imported injection molding machines is more than three times that of domestic machines, and the prices of imported extruders and granulators have exceeded 30 times. Many plastic machinery manufacturers in the low-end market will withdraw from the market within the next five years. For a long time, the uniformity and fixedness of the models and functional specifications of plastic machinery have not been able to meet the market demand. Due to the frequent changes in the production of plastic products and the consideration of effective investment in operation, the plastic machinery industry is required to provide the most adaptable plastic machinery and equipment; on the other hand, with the rapid development of industrialization to commercialization, Large-scale and large-scale production is also an inevitable law of manufacturing. If plastic machinery is not eliminated, it must develop towards the following five points:
First, increase efforts to develop precision injection molding machines and precision extruders
At present, precision injection molding machines are mainly foreign brands. Of the approximately 20,000 plastic presses imported annually in China, 60% are precision injection molding machines. In the aspect of multi-layer co-extrusion machines, China's presses are still difficult to compare with foreign presses in terms of precise control of layer thickness. Biaxially oriented PET (PA, BOPP) film units and precision medical catheter extrusion units in extrusion equipment 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.
Second, the development of mainframes and microcomputers
China's small and medium-sized plastic machinery categories and specifications are relatively complete, but mainframes and micro-computers are still in their infancy. The design and manufacture of large and micro plastic machinery is closely related to the country's overall mechanical manufacturing and material technology level. At the initial stage, the relevant technical foundation and intellectual property system should be established. Miniaturization is an important development direction for various products in the future. More and more market demands are now showing examples of obvious development momentum in the electronics, information, electrical, medical, and biological sectors. For example, plastic tube production equipment with a diameter of less than 0.5 mm for replacing human blood vessels is already under development in some countries.
Third, the development of energy-saving 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. Adopting advanced energy-saving technology, the power conversion efficiency of the variable frequency speed control motor is obviously higher than that of the previous electromagnetic speed regulating motor and DC motor. With the maturity of the frequency conversion speed regulation technology and the cost reduction of the frequency converter, in the plastic machinery, special It is widely used in extrusion equipment.
Fourth, the development of automation and intelligent plastic press
Automation and intelligentization, the development of intelligent plastic press will significantly improve the operation stability and reliability of the press, and effectively improve the high-quality, high-efficiency, low-consumption production functions of the press, and realize the unmanned workshop and no one. The factory provides a solid technical foundation;
V. Networking and Virtualization
Networked management technology can be seen as a technology outside of the device, but it is indeed inseparable from the device. From the auxiliary equipment manufacturer to the host manufacturer, the networked management system is one of the control functions that the device can provide. This will promote a higher level of international integrated design and manufacturing, and the implementation of more sophisticated plastic machine specialization.
In recent years, China's plastic machinery industry has experienced rapid growth in the market, and manufacturers of high-end, high-efficiency, energy-saving and high-tech products have been continuously integrated. As the domestic plastic machinery industry gradually enters the high-tech, high-addition development stage, improving product quality and research and development capabilities has become an important part of increasing the company's core competitiveness. The plastics industry should seize the opportunity to make China's plastic machinery industry achieve a brilliant annual growth rate with a higher average annual growth rate.
