Research and Analysis on the development of plasti

  • Detail

In recent years, China's plastic machinery industry has accelerated the development of new products and technologies by introducing, digesting and absorbing foreign advanced manufacturing technologies. At the same time, it has also been constantly exploring the international market. One third of the enterprises' products have been exported. The export volume has accounted for about 30% of the domestic sales volume, and the export growth rate has reached 20%

the mixture of poly (butylene terephthalate) (PBT) and acrylonitrile styrene acrylate copolymer (ASA) includes 30% (by weight) of glass fiber and a halogen flame retardant package. Taking pipe equipment as an example, since the first aluminum-plastic composite pipe production line was introduced in the mid-1990s, more than 50 manufacturers have produced the equipment in five years, and their key technologies such as welding and compounding of aluminum pipes have been well solved, The integrity and progressiveness of most products have reached the international advanced level

in the same period, advanced equipment such as steel plastic composite unit and Gas PE pipe unit have been successfully developed, and some key technologies have been solved, such as high-speed and high-efficiency single screw machine suitable for medium and high-density PE processing; High precision die head with good mixing effect, short residence time, no melting trace and advanced configuration for shaping, cooling, traction, cutting, thickness measurement, etc

with the sustained and rapid development of the national economy, the continuous improvement of people's living standards, the continuous promotion of energy conservation, environmental protection and green low-carbon economy, China's per capita plastic consumption will grow faster, and the development prospect of China's plastic machinery industry will be better. At the same time, China's plastic machinery market has attracted more and more attention from foreign enterprises. Many large international enterprises not only continuously increase the depth and breadth of cooperation with China's plastic machinery enterprises, but also occupy China's plastic machinery market by means of merger or purchase of shares. This shows the development potential and advantages of the plastic machinery industry

the improvement of the level of plastic machinery and equipment is also reflected in the fact that the complete set of equipment has been widely valued. Especially in extrusion molding, the concept of main and auxiliary machines has been deeply rooted for many years. Most manufacturers only provide main machines, and the proportion of main and auxiliary machines is out of balance. This situation has changed a lot. At present, most foam plastic manufacturers can provide a full set of extrusion production lines and even undertake turnkey projects without receiving and using extruders

but the polishing damage layer is also deep; The latter requires the use of fine materials
