The hottest plastic machinery industry is developi

  • Detail

The plastic machinery industry has developed rapidly and the market is broad.

through years of efforts and continuous innovation and development, plastic machinery has become an important pillar of the development of the plastic industry. It provides advanced technical equipment for the plastic industry. Its development is the basis for the development of the plastic industry. At the same time, it is also affected by the improvement of enterprises, the progress of the industry, the utilization of resources, the development of society and the development of the material industry. In the long-term plan of China's plastic 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 25million tons by 2005. It is expected that the total output of plastic products will double to 50million tons in 2015

the good development prospect of plastic processing industry will still be the source power for the rapid development of China's plastic machinery manufacturing industry. It is estimated that the average annual growth rate of China's demand for plastic machinery is about 6% from 2001 to 2010, and it is expected to be 14.5 billion yuan by 2010. In other words, the development potential of China's plastic machine industry is great, and there is a lot of momentum, especially some models with high scientific and technological content, good performance and moderate price, such as super large, precision and special injection molding machines, low-temperature and high-power single screw extruders, multi-layer coextrusion blow molding machines for the production of high impermeability and heat-resistant 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 production lines and blow molding machines, which account for more than 80% of the total output value of plastic machinery, of which injection molding machines account for more than half of the total of these three types of machinery

injection molding machines push through the old and bring forth the new. Due to the rapid development of injection molding machines in previous years, now in addition to large machines, the supply of injection molding machines of general specifications has exceeded the demand; However, the market demand for some high-tech injection molding machines has gradually strengthened. There are mainly the following models: first, all electric and all hydraulic precision injection molding machines. The main markets of these products are electronic communications, audio-visual products, household appliances, automobiles, etc. the requirements for processing conditions are high, and the requirements for the precision of injection molding machines are also improved. These industries are sunrise industries, and there is great room for development

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

the third is a new 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 high appearance requirements and long service life, such as household appliances, automobiles, buildings, etc

extruders are cheap and good. Due to the continuous expansion of the application market and technological breakthroughs, the extruder market can still maintain a slight upward trend on the whole, but the sharp decline in the market price of domestic extruders is inevitable. Rough manufacturing and price war have affected the overall image and market competitiveness of domestic plastic machines, and also hindered the development of plastic processing industry. In the past two years, Kraus Maffei, a German company alone, has provided China with more than 100 profile production lines. Most of the powerful enterprises in the plastic door and window and pipe processing industry have sought to import equipment, which can not be said to be the failure of domestic manufacturers

in the future, the market of extruder host and production line will develop in the direction of high technology content and low price. Domestic main engines are now basically 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 the demand, and can only maintain about 50% - 60% of the market peak period. In the future, the main focus of the host machine is to develop parallel counter rotating twin-screw extruder, which is suitable for molding and extrusion with large extrusion volume. The parallel co rotating twin-screw extruder should develop towards the sixth and seventh generation of high-speed, large-diameter temperature boxes, such as those used in the experiment of military products, which should not only meet the requirements of the national military standards gjb150.3-86 and gjb150.4-86 according to different uniformity and temperature control accuracy. 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 and low-cost model. As long as the technology is appropriate, it can basically achieve the efficiency of the twin-screw extruder. For example, most of the plastic extruders used in the United States are single screw extruders, which replace the twin-screw extruders due to their high technical content

blow molding machines are developing rapidly. The price of blow molding equipment is low (about one-third to one-half of that of injection molding), energy consumption is low (in injection molding, the pressure in the mold cavity is 15 ~ 140MPa, while the inflation pressure of the parison during blow molding is generally less than 1MPa), and adaptability is strong (complex structure and double wall parts can be molded). It makes up for the shortcomings of injection molding processing methods. The molded industrial parts have high integrity and good comprehensive performance, High added value and low cost. Therefore, although blow molding machinery accounts for the lowest proportion of the three plastic machines at present, it will maintain a strong momentum of development in the future, and it is the model with the fastest development and the most development potential

plastic auxiliary equipment, such as mixers, shredders, feeders, heaters and other auxiliary equipment, is an important part of the plastic production line, which directly affects the production quality and production efficiency of products. At present, domestic manufacturers are overwhelming, but the varieties and specifications are basically within the same range, and the technical dimensions are: width (15 ± 0.1) mm, development length (100 ± 1) mm, which is difficult to compete with imported machines, Moreover, 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, so the domestic auxiliary machine market competition is fierce. Market capacity does not match the number of enterprises, which is bound to cause this situation. The recent development direction of this kind of products is to have the functions of ultra-fine crushing (preparing for the nano material industry), vacuum filtration, large-scale low noise, high-speed crushing and so on
