Plastic machinery is an important pillar for the development of the plastics industry. It provides advanced technology and equipment for the plastics industry. Its development is the basis for the development of the plastics industry and is also influenced by the development of the plastics industry. From a worldwide perspective, the three major categories of plastic machinery are injection molding machines, extruders/extrusion lines, and blow molding machines, which account for more than 80% of the total output value of plastic machinery. Injection molding machines account for the sum of these three types of machinery. More than half. The industry believes that the market outlook for these three types of plastic machinery is promising.
Strong demand for high-tech injection molding machines Strong demand for injection molding machines Due to the rapid development of injection molding machines in the past few years, in addition to mainframes, the general specification of injection molding machines has exceeded supply, and sales volume can be maintained at about 1/3 of the peak period. However, with some high-tech injection molding machines, market demand has gradually increased. The first is an all-electric, fully hydraulic precision injection molding machine. The main markets for this type of products are electronic communications, audio-visual products, home appliances, and automobiles. The processing conditions are relatively high, and the precision requirements for injection molding machines have also been increased. These industries are all Chaoyang industries and have a lot of room for growth. The second is the rapid development of hollow injection molding machines. This is due to the stress damage of plastic parts in the vibration state is a major problem in the automotive plastic 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 injection molding machine with air assistance and water assistance. This kind of technology has a large market in the near future, especially for products with higher appearance requirements and longer service life, such as household appliances, automobiles, and buildings.
The lack of competitiveness of domestic extruders Extruder market due to the continuous expansion of the application market and technical breakthroughs, in general, can maintain a slight upward trend, but the domestic price of the extruder market has fallen is difficult to avoid, shoddy and price war It has affected the overall image and market competitiveness of the domestic presses, and has also hindered the development of the plastics processing industry. In the last two years, only the German company Klaus Maffei has dealt with more than one hundred foreign profile production lines with Chinese transactions. Most of the enterprises with strong strengths in the plastic doors, windows, and pipe processing industries are seeking imported equipment. This can not be said to be domestic The failure of the manufacturer. The future market for extruders and production lines will develop in the direction of increasing technological content and reducing prices. Domestic mainframes are now mainly conical twin-screw extruders and single-screw extruders. The technology is relatively mature and the market sales volume is also the largest. However, the general specifications of these products have exceeded supply, and can only maintain the peak of the market. 50%-60%. The main focus of the host in the future is the development of parallel counter-rotating twin-screw extruders, which are suitable for extrusion and extrusion of large extrusion volumes. Parallel co-rotating twin-screw extruders are to be developed toward sixth-generation and seventh-generation high-speed, high aspect ratios. The development direction of single screw extruder is large diameter, large ratio of length to diameter, and smooth exhaust. In fact, a single-screw extruder is a low-energy, low-cost model. As long as the technology is right, it can basically achieve the performance of twin-screw extrusion. For example, the plastic extruder used in the United States is mostly single. Screw, due to its high technological content, replaced the twin-screw extruder.
Blow molding machines have the most potential for development Blow-molding equipment is cheap (about 1/3-1/2 injection molding), low energy consumption (in injection molding, the pressure inside the mold cavity is 15-140 MPa, while blowing The inflation pressure of the parison is generally lower than 1 MPa), and the adaptability is strong (the structure of the mold can be complex, double-walled parts), which makes up for the lack of injection molding processing methods, and the formed industrial parts have a high degree of integrity, overall performance Good, high added value, low cost. Therefore, although blow molding machinery currently accounts for the lowest proportion among the three major presses, it will maintain a strong momentum of development in the future. It is the fastest growing and most promising model. 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, by 2005, the output of plastic products will reach 25 million tons. It is expected that the total output of plastic products will double in 2015 to reach 50 million tons. The good prospects for the development of the plastics processing industry will continue to be the driving force behind 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 plastics machinery will be about 6%, and it is expected to reach 14.5 billion yuan by 2010. .
