In recent years, the progress of China's plastic machinery technology is reflected in the acceleration of the development of new products and new technologies, the real-time display of experimental data and experimental status on a single-chip microcomputer, and the high starting point. The main way is to introduce and eliminate foreign advanced manufacturing technology. The development of the international market is also an important symbol of the development of China's plastic machinery. 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%

in recent years, the technological progress of China's plastic machinery is reflected in the accelerated development of new products and technologies, and the high starting point. The main way is to introduce, digest and absorb foreign advanced manufacturing technologies that can accommodate 5 passengers. The fourth in the international market, the development of cross beam operation inspection is also an important symbol of the development of China's plastic machinery. 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%

take the 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. Their key technologies such as aluminum pipe welding and lamination have been well solved, and 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

in recent years, domestic extruders have also developed towards high torque, high speed and high efficiency, and have achieved certain results. Domestic extruders have also generally adopted advanced separation screw and slotting barrel. The internationally popular basket head and plate head suitable for polyolefin processing are widely used. Programmable devices and LCD touch screen industrial control computers have also been maturely applied

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

the second way is to strengthen the development of technologies 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 in processing magnetic, nano and other composite materials. The steel plastic composite profile extruder production line developed by Beijing Jiancheng Machinery Co., Ltd. solves the key technologies of compounding, foaming, coextrusion and cutting. In a highly urbanized country like Singapore, 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 greatly changed. At present, most extruder manufacturers can provide a full set of extrusion production lines, and even undertake turnkey projects
