Chinas plastic machinery technology progress towards the international level
In recent years, China's plastics machinery technology progress performance in new products, new technology development speed, higher 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 the development of China's plastics machinery, 1/3 of the enterprise product exports, exports accounted for about 30% of domestic sales, export growth rate of 20%.
The pipe equipment as an example, the last century the mid 90s introduced the first aluminum-plastic composite pipe production line, the production equipment 5 years manufacturers have more than and 50, the key technologies such as aluminum welding and composite are solved, the integrity and the advanced nature of most of the products have reached the international advanced level.
In the same period and the successful development of steel plastic composite unit, Gas PE pipe unit and other advanced equipment, and solve some key technologies, such as high speed high efficiency single screw machine is suitable for high density PE processing; good mixing effect, short retention time, high precision die without melting trace and in shaping, cooling, traction, cutting, thickness and configuration.
In recent years, the domestic extruder toward the high torque, high speed and high efficiency of development and achieved certain results, domestic extruder is generally used by the advanced separation type screw and slotted barrel head, commonly used basket nose and plate type nose international popular for polyolefin processing, touch screen computer have mature application of programmable device and liquid crystal display.
Plastic film processing equipment with spiral die manufacturing technology popularization, to promote the use of superposition head, multi-layer co extruded film has reached 5, geomembrane used in cold extruding technology, film width has reached 2 meters.
The two way is through technological innovation, to strengthen the development of intellectual property rights. Beijing University of Chemical Technology Professor Jin and Beijing Fong Kee Plastic Machinery Co. Ltd. has developed a disc mixing extruder, compared with the traditional mixing equipment, improve the fineness of material dispersion mixing effect, expand the scope of the processing of raw materials, has significant advantages for the processing of magnetic nano composite materials, etc.. Machine production line design of Beijing Jiancheng machinery limited company of steel plastic composite extrusion and solved the key technology, composite foam, CO extrusion, cutting etc.. Shanghai jwell extrusion machine manufacturing Co., Ltd. developed the PET/GPET co extrusion production line, the width of up to 2 meters.
The improvement of the level of plastic machinery and equipment, but also the performance of the complete sets of equipment has been widely valued. Especially in extrusion molding, ingrained over the years for the majority of manufacturers only provide the host, main and auxiliary imbalance, this situation has changed dramatically, most extruder manufacturers can provide a full range of extrusion production line, can even bear a turnkey project.
