China's plastics machinery and technological progress particles gradually move towards the international level

 In recent years, China's plastics machinery and technological progress in the performance of new products, new technology development speed, high starting point, the main way is through the introduction, digestion and absorption of foreign advanced manufacturing technology. International market development is also an important symbol of China's plastics machinery, has one-third of enterprises export, the export volume accounts for about 30% of domestic sales, and export growth rate of 20%. To pipe equipment, for example, the mid-90s of the last century since the introduction of the first plastic composite pipe production line, the manufacturer of the device there are more than 5 years, 50 key technologies such as aluminum welding, complex have been a better solution, most of the products of integrity and advanced to the international advanced level. During the same period there developed a successful plastic composite units, gas PE pipe mill and other advanced equipment, and addresses a number of key technologies, such as high-density PE suitable for processing high-speed and efficient single screw extruder; mixing effect, the residence time is short, No melting traces precision die and advanced styling, cooling, pulling, cutting, thickness measurement configurations. In recent years, domestic extruders also towards high torque, high speed, high efficiency development and achieved some success, domestic extruders are commonly used by the advanced separation type slotted screw and barrel, head commonly used international popular suitable for processing polyolefins basket nose and nose plate, and programmable LCD touch screen IPC has also been mature application. Plastic film processing equipment using manufacturing technology increasing popularity spiral head superimposed head to promote the application of multi-layer co-extruded film has reached 5, geomembranes are used within the cooling technology, co-extruded cast film width has been reached 2 m. The second way is through technological innovation, strengthening intellectual property rights developed technology. Professor Jiang Bo Beijing University of Chemical Technology and Beijing Fung Kee Plastic Machinery Co., Ltd. has developed a disc-type mixing extruder, compared with conventional mixing equipment, improve the fineness of materials, degree of dispersion, such as mixing effect, expanding the processing of raw materials range, for processing magnetic nanotechnology and other composite materials having significant advantages. Developed Plastic Machinery Co., Ltd., Beijing Jian Cheng composite profile extrusion production line while addressing the complex, foam, extrusion, cutting and other key technologies. Shanghai Jin Wei extruder Manufacturing Co. has developed a PET / GPET coextrusion line, the width of up to 2 meters. Improve the level of plastic machinery and equipment, but also in complete sets of equipment have been widespread attention. Especially in the extrusion molding, over the years the main auxiliary of deeply entrenched, most manufacturers only offer a host, main, auxiliary imbalance, this situation has changed dramatically, now most extruder manufacturers can A full extrusion lines, and even undertake turnkey projects.
