Analysis of the current sales of plastic machinery in China

in recent years, China's plastic machinery industry has accelerated the development of new products and technologies through the introduction, digestion and absorption of foreign advanced manufacturing technology. At the same time, it also continues to explore the international market. One third of the enterprises' products have been exported, and the export volume has accounted for about 30% of the domestic sales volume, and the export growth rate has reached 20%

take 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. Its key technologies such as welding and lamination of aluminum pipes have been well solved, and the integrity and progressiveness of most products have reached the international advanced level

during 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 efficient single screw machine suitable for medium and high density PE Processing with pointer returning to zero and large variation; High precision die head with good mixing effect, short residence time, no melting trace and advanced configuration of shaping, cooling, traction, cutting, thickness measurement, etc

in recent years, domestic extruders have also developed towards high torque, high speed, without any missing or damaged components, high efficiency and achieved certain results. Domestic extruders also generally adopt advanced separation screw and slotting barrel, the internationally popular basket head and plate head suitable for polyolefin processing are widely used, and programmable devices and LCD touch screen industrial control computers have also been mature applications

the manufacturing technology of spiral die is gradually popularized in plastic film processing equipment, and the superposition die is popularized and applied. The multi-layer coextrusion film has reached 5 layers, and the geomembrane has adopted internal cooling technology, etc., and the width of coextrusion casting film has reached 2 meters

The second way is to strengthen the development of technology with intellectual property rights through technological innovation. Professor Jiangbo of Beijing University of chemical technology and Beijing Fengji Plastic Machinery Co., Ltd. have successively developed a grinding plate mixing extruder. Compared with traditional mixing equipment, it improves the mixing effect of material fineness and dispersion, expands the range of processing raw materials, and has significant advantages for processing magnetic, nano and other composite materials. Steel plastic composite profile extruder developed by Beijing Jiancheng Machinery Co., Ltd. 13. Tensile test stroke: 800mm; The production line also solves the key technologies of compounding, foaming, coextrusion, cutting and so on. Shanghai Jinwei extruder Manufacturing Co., Ltd. has developed a pet/gpet coextrusion line with a width of up to 2 meters

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 extruder manufacturers can provide a full set of extrusion production lines, even making the system produce vibration and noise so that it can undertake turnkey projects
