With the continuous expansion of the application field of Dongguan extruder and the continuous progress of technology, the market of extruder still maintains a certain upward trend, but the price of domestic extruder has dropped sharply. Some manufacturers shoddy, vicious price war, affecting the overall image of domestic plastic machine and market competitiveness, but also hinder the development of plastic processing industry.
Experts believe that in the future, the market for extruder mainframes and production lines will develop in the direction of high-tech content and lower prices. As far as molding equipment is concerned, the domestic host is mainly conical twin screw extruder and single screw extruder, with mature technology and the largest market sales. However, the general specifications of these products have been in short supply, and can only be maintained at about 50% to 60% of the peak of the market. In the future, the domestic host market should focus on the development of parallel antidirectional twin screw extruder to meet the molding needs of large extrusion. Parallel twin screw extruder will develop to the sixth and seventh generation of high speed and large aspect ratio. The single-screw extruder is developing in the direction of super large, ultra-micro, large aspect ratio, high output and good exhaust performance. The screw barrel structure adapted to the special processing needs has become the focus of research and development. In fact, the single screw extruder is a low energy consumption and low cost model. As long as the process is proper and the structure design is reasonable, the performance of the twin-screw extruder can also be achieved. According to reports, the plastic extruder currently used in the United States is mainly a single screw. High-technology single-screw extruder is gradually replacing twin-screw extruder in some fields.
Although China's Dongguan extractor market has developed rapidly and launched a lot of new models, it cannot be ignored that China's extractor technology still lags far behind foreign developed countries.
