Domestically, China is still in an advanced stage of industrialization, informatization, urbanization, marketization, and internationalization, and it is still in an important period of strategic opportunities for development. This will also provide an inexhaustible driving force for the development of the extruder industry. Finally, the warming of the international market has brought confidence to the extruder companies.
Future international influence of China's plastics extruder will continue to heat up Chinese plastic extrusion machine industry through long-term development, plastic extrusion machine industry's international influence continues to heat up, answering trade concern doctrine intelligence enhancement, further enhance the level of industrial technology. As China's extruder products are closely linked with strategic new industries, they have the advantages of high efficiency, energy saving, and high cost performance. The exports to developed countries are mainly in the low-end market. This part of the consumer demand is rigid, and therefore, the extruder The development of the industry still has a large market space.
Although the extruder market in China has developed rapidly, the export ratio of extruders remains low. The rising cost of raw materials and the pressure on energy costs have made energy-saving and material-saving the focus of the extrusion and processing industry. At the same time, extrusion technology suppliers are able to develop a variety of energy-saving solutions from a variety of perspectives in order to best meet the energy-saving needs of users.
Through the joint efforts of industry technology and R&D personnel, some major special machines such as exhaust extruders, tandem disc screw extruders, reciprocating pin screw extruders, foam extruders, and melt gear pumps Extruders, tandem multi-stage extruders, planetary screw extruders, etc. are all manufactured in China, with independent research and development capabilities, and enjoy independent intellectual property rights.
The extruder can be divided into single-screw, twin-screw and multi-screw extruders according to the number of its screws. At present, the single-screw extruder is the most widely used and suitable for extrusion processing of general materials. The twin-screw extruder has less heat due to friction, more uniform shearing of the material, greater screw conveying capacity, relatively stable extrusion volume, long stay of material in the barrel, and even mixing. SJSZ series conical twin-screw extruder has the characteristics of forced extrusion, high quality, wide adaptability, long life, low shear rate, material is not easy to decompose, good mixing and plasticization performance, direct molding of powder, etc. Vacuum exhaust and other devices.
In recent years, a large number of theoretical and experimental studies on screw have been carried out. Up to now, there have been nearly 100 kinds of screws. Commonly used are separation type, shear type, barrier type, shunt type and wavy type. From the standpoint of single-screw development, although single-screw extruders have been relatively complete in recent years, with the continuous development of polymer materials and plastic products, more innovative new-type screws and special single-screw extruders will emerge.
In plastic extrusion molding equipment, plastic extruders are often referred to as mainframes, and their accompanying follow-up equipment, plastic extrusion molding machines, are called auxiliary machines. After more than 100 years of development, plastic extruders have derived twin screw, multi-screw, and even screwless models from the original single screw.
The root cause of the development of China's plastic extruder In recent years, China's plastic extruder has not paid much attention to R&D and innovation. Most Chinese enterprises have chosen more foreign plastic extruder equipment, and have paid more attention to the coastal areas of China. Short-term profit-making purposes, while the late technology-based technology has become a foreign development and design patents, especially foreign companies have begun to specialize in technology research and development for the Chinese market. This is for the development of their plastic extrusion machine industry is extremely unfavorable to earn just the cost of the industrial chain in cheaper part of the long run foreign companies will monopolize the Chinese market plastic extruder, faced with this embarrassing situation of Chinese enterprises We must speed up the adjustment of the industrial structure and increase the degree of independent innovation in order to push the plastic extruder industry out of its predicament.
Development of the times to the plastic extrusion machine industry has brought new opportunities for development, the current plastic profile industry of plastic profiles, plastic pipes, plastic sheets and other products has become a huge chain of chemical building materials industry in China, expects its future market The total demand is expected to reach 13.26 million tons, providing undoubtedly a powerful driving force for the development of the entire industry. As plastic extruders serve various industries and develop in depth, it is possible to transition to market consumption. Through various means, improve the technical level. This will not only help improve the overall level of the industry, but also help the industry to develop in the direction of social specialization and enhance international competitiveness.
In the future, the international influence of China's plastic extruder will continue to heat up
After long-term development, the international influence of plastic machinery industry continues to improve, enhance the ability to deal with trade protectionism, manufacturing technology and further improve the overall strength, therefore, a lot of favorable conditions for the extruder industry in terms of foreign trade exports. As China's extruder products are closely linked with strategic new industries, they have the advantages of high efficiency, energy saving, and high cost performance. The exports to developed countries are mainly in the low-end market. This part of the consumer demand is rigid, and therefore, the extruder The development of the industry still has a large market space.
