Through years of efforts and continuous innovation and development, plastic machinery has become an important pillar of the development of the plastics industry. It provides advanced technology and equipment for the plastics industry, and its development is the basis for the development of the plastics industry, and it is also affected by the development of the plastics industry. In the long-term planning of China's plastics industry, the average annual growth rate of plastic products from 2000 to 2005 is about 10%, and the average annual growth rate from 2006 to 2015 will reach 8%, that is, the output of plastic products will reach 25 million tons by 2005, and the total output of plastic products is expected to double to 50 million tons by 2015.

The good development prospects of the plastics processing industry will still be the driving force for the rapid development of China's plastics machinery manufacturing industry. It is estimated that from 2001 to 2010, the average annual growth rate of China's demand for plastic machinery is about 6%, and it is expected to be 14.5 billion yuan by 2010. That is to say, the development potential of China's plastic machine industry is great, and the stamina is sufficient, especially some models with high technology content, good performance and relatively moderate price, such as super large, precision and special injection molding machines, low temperature and high power single screw extruders, multi-layer co-extrusion blow molding machines for the production of high permeability and heat resistance packaging materials, etc., have good development prospects. From the perspective of the global market, the varieties of plastic machinery are mainly composed of injection molding machines, extruders/extrusion lines and blow molding machines. They account for more than 80% of the total output value of plastic machinery, and injection molding machines account for these three types. More than half of the total machinery.

Due to the rapid development of injection molding machines in the past few years, in addition to mainframes, the supply of injection molding machines of general specifications has exceeded demand. However, the market demand for some injection molding machines with high scientific and technological content has gradually strengthened. There are mainly the following models: First, all-electric, all-hydraulic precision injection molding machine. The main market for such products is electronic communications, audio and video, home appliances, automobiles, etc. The processing conditions require higher requirements, and the precision requirements of injection molding machines have also increased. These industries are all sunrise industries and have great room for development.

Two is a hollow injection molding machine. This is because the stress failure of plastic parts under vibration is a big problem in automobile full plasticization and other engineering applications, and a variety of rubber and plastic materials combined with hollow injection molding technology can effectively improve the above defects.

The third is a new type of injection molding machine with air-assisted and water-assisted devices. This new type of injection molding machine has a large market, especially for products with higher appearance requirements and longer service life, such as home appliances, automobiles, and buildings.

Due to the continuous expansion of the application market and technological breakthroughs, the extruder market can generally maintain a slight upward momentum, but the sharp decline in the price of the domestic extruder market is inevitable, shoddy and price wars have affected the overall image and market competitiveness of domestic presses, and also hindered the development of the plastics processing industry. In the past two years, Klaus Maffei, a German company alone, has provided more than 100 profile production lines to China. Most of the powerful enterprises in the plastic doors, windows and pipe processing industry have sought to import equipment. This cannot but be said to be the failure of domestic manufacturers.

The future market of extruder host and production line will develop in the direction of high technology content and low price. Domestic hosts are now basically conical twin-screw extruders and single-screw extruders. The technology is more mature and the market sales are the largest. However, the general specifications of such products have exceeded demand and can only maintain the peak of the market. About 50% ~ 60%. The future focus of the host is on the development of parallel twin-screw extruder, suitable for large extrusion molding extrusion. Parallel co-rotating twin-screw extruder to the sixth generation, the seventh generation of high-speed, large aspect ratio direction. The development direction of single screw extruder is large diameter, large aspect ratio and smooth exhaust. In fact, the single-screw extruder is a low-energy, low-cost model, as long as the technology is appropriate, it can basically achieve the efficiency of the twin-screw extruder, such as the United States now use most of the plastic extruder is single-screw, due to the high technical content, replaced the twin-screw extruder.

The rapid development of blow molding machine blow molding equipment has low price (about 1/3 to 1/2 of injection molding), low energy consumption (during injection molding, the pressure in the mold cavity is 15 ~ 140MPa, while the inflation pressure of the parison during blow molding is generally lower than 1MPa), strong adaptability (it can form parts with complex structure and double walls), which makes up for the deficiency of injection molding processing method, and the formed industrial parts have high integrity, good comprehensive performance, high added value and low cost. Therefore, although the current blow molding machinery in the three plastic machine in the proportion of the lowest, but the future will maintain a strong momentum of development, is the fastest growing, but also the most potential for development models.

Plastic auxiliary equipment such as mixing machine, crusher, feeding machine, heater and other auxiliary equipment is an important part of the plastic production line, which directly affects the production quality and production efficiency of the products. At present, there are numerous domestic manufacturers, but the varieties and specifications are basically in the same range, and it is difficult to compete with imported machines technically. Most imported plastic production lines have been equipped with the above auxiliary machines when they are introduced, which reduces the sales volume by a part, therefore, domestic auxiliary market competition is fierce. Market capacity and the number of enterprises do not match, is bound to cause this situation. The recent development direction of this kind of products is to have the functions of ultra-fine grinding (preparing for the nano-material industry), vacuum filtration, large-scale low noise, high-speed crushing and so on.
