The pace of industrialization of the plastic machinery industry is accelerating

Before and after 2005, it can be said that it is the golden period for the development of plastic machinery enterprises. At that time, the number of plastic enterprises was born. However, since plastic machinery companies all want to develop their own, each fights and does not cooperate, it leads to the industry and The best time to pass. Now the overall technology of the plastic machinery industry has matured, but in the absence of communication and sharing, the industrial chain structure is not perfect, and large-scale promotion is still unrealistic.

So far, the number of plastic machinery manufacturing enterprises in the country has grown to more than 1,000, but there are about 400 enterprises with certain scale and strength. Compared with foreign developed countries, China’s total consumption of plastic products has ranked second in the world. However, the per capita plastic consumption is quite different from that of developed countries.

Plastic machinery companies are each camped, not ventilated, and capital investment is also implemented in accordance with the understanding of the market and the company's own development strategy. Lack of technology in enterprises, lack of competitiveness, lack of industry standards and leading enterprises in the industry may be the plastics industry is over-investment, and the undesirable circulation vortex becomes a common phenomenon. But at the same time, it shows that China's plastic machine industry has huge space for excavation and development in the future, especially some models with high technology content, good performance and relatively moderate price, such as extra large, precision and special injection molding machines, which are used to produce high barrier. Multi-layer co-extrusion blow molding machines for heat and heat-resistant packaging materials, and production of industrial parts (auto parts, etc.) blow molding machines, etc., have good development prospects.

Then, if there is any remedy for the rapid development of plastic machinery, the experts suggest that the government departments, industry research institutes and other organizations take the lead in formulating system standards and set a "rule" for the market. The upstream and downstream enterprises of the press machine work together to “bring the group to warm up” and jointly commit themselves to the development of environmental protection. With the rapid evolution of industrialization to commercialization, large-scale and high-volume production has become an inevitable law of the manufacturing industry. The future plastic machinery may start from the five major development directions to resist the elimination wave of the industry.

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 in China each year, 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 very necessary to develop domestically produced precision injection molding and extrusion equipment with independent intellectual property rights. It can not only replace imports, but 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 injection molding machines, 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 is almost 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.
