The progress of China's plastic machinery technology is moving towards the international level

- Jan 03, 2018-

In recent years, the technological progress of China's plastics machinery has shown that the development speed of new products and technologies is accelerating and the starting point is relatively high. The main way is to import and digest advanced foreign manufacturing technologies. The opening up of the international market is also an important symbol of the development of our plastics machinery. 1/3 of the enterprises have exported products, and the export volume has accounted for about 30% of the domestic sales, and the export growth rate has reached 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 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 has been popularized by spiral head manufacturing technology. The stacking die has been popularized and applied. The multi-layer co extrusion film has reached 5 layers, and the geomembrane has adopted the internal cooling technology. The width of the coextrusion tape has reached 2 meters.

The two way is to strengthen the development of intellectual property technology through technological innovation. 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 Jinwei extruder Manufacturing Co., Ltd. developed a PET/GPET co extrusion line with a width of up to 2 meters.

The improvement of the level of the plastic machinery and equipment has been paid much attention to in the complete set of equipment. 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.
