Adjusting the structure of China's plastic machinery to promote the development space of the extruder industry. At present, the development status of domestic plastic machinery industry is that there are such problems as low independent innovation ability, few personalized varieties and low industry concentration. The existence of these problems leads to the fact that China's plastic machinery industry can not catch up with the level of foreign plastic machinery as soon as possible.
After long-term development, the influence of China's plastic machinery industry has been continuously improved, the ability to deal with trade protectionism has been enhanced, and the manufacturing technology level and overall strength have been further improved. Therefore, China's extruder industry has many favorable conditions in terms of foreign trade and export. As China's extruder products are closely linked with strategic new industries, with the advantages of energy saving and high cost performance, and exports to developed countries are mainly at the middle and low end, this part of consumer demand is rigid. Therefore, there is still a large market space for the development of the extruder industry.
With the long-term development of China's plastic extruder industry, the influence of the plastic extruder industry continues to rise, and the industrial technology level is further improved. As China's extruder products are closely linked with strategic new industries, with the advantages of energy saving and high cost performance, and exports to developed countries are mainly at the middle and low end, this part of consumer demand is rigid. Therefore, there is still a large market space for the development of the extruder industry.
The extruder Market in China is developing rapidly, but the export proportion of extruders is still low. The pressure of rising raw material cost and energy cost makes energy saving and material saving become the key points concerned by the extrusion processing industry. At the same time, extrusion technology suppliers have developed rich energy-saving schemes from various angles to meet the energy-saving needs of users to a large extent. In recent years, people have done a lot of theoretical and Experimental Research on screw. Up to now, there are nearly 100 kinds of screw, including separation type, shear type, barrier type, shunt type and wavy type. In terms of the development of single screw, although the single screw extruder has been relatively perfect in recent years, with the continuous development of polymer materials and plastic products, more characteristic new screws and special single screw extruders will emerge.
In the plastic extrusion equipment, the plastic extruder is usually referred to as the main machine, while its supporting follow-up equipment, the plastic extrusion machine, is referred to as the auxiliary machine. After more than 100 years of development, plastic extruders have been derived from the original single screw into twin-screw, multi screw and even non screw models. The technology of plastic extruder industry will have a qualitative leap, and will no longer rely on imports. Its influence in China will continue to rise, and its development prospect is optimistic.
