Plastic machinery plays an important role in plastic production. Since the beginning of the 21st century, China's plastic machinery industry has achieved sustained and rapid development. It is one of the fastest growing industries in China, and its main economic indicators are in the forefront of China's machinery industry.

At present, there are 546 domestic plastic machinery manufacturers in China, most of which produce injection molding machines, and the top ten in the industry account for 39% of the total sales volume of the industry. Over the past five years, relying on technology promotion and highly competitive prices, our manufacturers have built businesses and successfully challenged Germany and Japan, Europe and the United States and other developed markets.

However, China is still an important importer of plastic machinery. Because the plastic machinery enterprises in China mainly produce low-end plastic machinery, and many kinds of plastic machinery are lack of production technology, the export price of plastic machinery in China is generally low and lack of international competitiveness.

The price of imported injection molding machines is more than three times that of domestic machines, and the price of imported extruders and granulators has exceeded 30 times. In the low-end market, many plastic machinery manufacturers will withdraw from the market in the next five years.

For a long time, plastic machinery models, functions and specifications of uniform and fixed has been unable to meet the market demand. Customers need plastic machinery industry to provide them with the plastic machinery equipment with the most market adaptability due to the frequent changes in the requirements of plastic products and the consideration of effective investment in operation;

On the other hand, with the rapid development of industrialization to commercialization, large-scale and mass production is also the inevitable rule of manufacturing industry

1. Development of precision injection molding machine and precision extruder

At present, precision injection molding machines are mainly foreign brands. At present, 60% of China's annual import of about 20000 plastic machines are precision injection molding machines. In the aspect of multi-layer co extrusion machine, it is difficult for China's machine to compare with foreign machine in the technology of precise control of layer thickness.

Biaxially oriented pet (PA, BOPP) film extruder and precision medical catheter extruder are also 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 also make China occupy a place in the international high-end market of plastic machinery.

2. Development of mainframe and microcomputer

China's small and medium-sized plastic machinery categories, specifications are relatively complete, but the mainframe and microcomputer is still in its infancy. The design and manufacture of large and micro plastic machinery are closely related to the national overall machinery manufacturing and material technology level. We should pay attention to the establishment of relevant technical basis and intellectual property system at the initial stage.

Miniaturization is an important development direction of all kinds of products in the future, and there is more and more market demand. At present, it has shown obvious development momentum in electronics, information, electrical appliances, medical, biological and other departments, which is an example. For example, the production equipment of plastic tube with diameter less than 0.5mm, which is used to replace human blood vessels, has been under research and development in some countries.

3. Development of energy saving plastic machinery

The traditional plastic machinery still has a certain potential in energy saving, because the previous design only focused on the production capacity of single machine. 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 of processing unit weight products.

Therefore, it is necessary to optimize the mechanical structure, control mode and operation conditions of the equipment based on the minimum energy consumption. With the application of advanced energy-saving technology, the energy conversion efficiency of variable-frequency speed regulating motor is significantly higher than that of electromagnetic speed regulating motor and DC motor. With the maturity of variable-frequency speed regulating technology and the reduction of variable-frequency speed regulating cost, it has been widely used in plastic machinery, especially in extrusion equipment.

4. Development of automation and intelligent plastic machine

Automation and intelligence, the development of intelligent plastic machine will significantly improve the operation stability and reliability of plastic machine, effectively improve the production function of high quality, high efficiency and low consumption of plastic machine, and provide a solid technical foundation for the realization of unmanned workshop and factory.

5. Networking and virtualization

Network management technology can be regarded as a technology outside the equipment, but it is really inseparable from the equipment. From the auxiliary equipment manufacturers to the host equipment manufacturers, the network management system is regarded as one of the control functions that the equipment can provide. This will promote a higher level of international integrated design and manufacturing, the implementation of a more sound specialized production of plastic machinery.

In recent years, the Ministry of industry and information technology of the people's Republic of China (MIIT) has issued the "investment direction for technological progress and technological transformation of equipment industry (2010)" and other major strategies, which provide rare favorable conditions and important opportunities for accelerating the revitalization of China's plastic machinery industry. Plastic machinery industry enterprises should seize the opportunity to meet the challenge, make plastic machinery play a greater role in the process of national economic revitalization, and strive to promote China's plastic machinery manufacturing industry from a big country to a powerful country.
