What Are the Trends in the Development of Double Screw Extruders Nowadays?

Now is the era of rapid development in Internet technology. In the future, whether it is double screw extruders or other types of extruders, they will definitely develop towards intelligent, miniaturized, and multi-functional directions. This type of operation is not only convenient and safe, but also low-cost.


Although China's extruder market is growing rapidly and there are many new models being introduced, we cannot ignore the fact that there is still a large gap between China's extruder technology and that of developed countries abroad. When double screw extruders are used for fiberglass-reinforced compounding, if the fiberglass content exceeds 45%, the processing will become quite difficult.


At present, there is a phenomenon of pursuing immediate benefits in the domestic extruder machinery industry. Technical investment only accounts for a small part of the entire sales revenue share. Product technology is mainly based on measurements of imported equipment, lacking theoretical calculation and scientific experimentation as a basis. Competition is achieved through low-priced products, and most companies can only produce low-grade old products, making it difficult to achieve economies of scale. High speed and energy conservation have been the main theme of plastic machinery improvements in recent years.


In the face of market changes, double screw extruders need to meet higher requirements. Therefore, providing solutions for problems that may arise from high-speed production is one of the important directions for the technical innovation of twin screw extruder manufacturers.


Multi-functionality of double screw extruders


In terms of functionality, double screw extruders are no longer limited to the molding and compounding of polymer materials, and their uses have expanded to fields such as food, feed, explosives, building materials, packaging, pulp, and ceramics.


In addition, the “one-step extrusion process” that combines compounding and extrusion molding into one is also very attractive.


Large-scale and precision of double screw extruders


Realizing the large-scale production of extrusion molding equipment can reduce production costs, and this is particularly true for large double-screw pelletizing units, blown film units, and pipe groups. In China, large-scale equipment has long relied on imports. Now, research is being carried out for the localization of large double-screw pelletizing units. Precision can increase the value of products, such as multi-layer composite co-extruded film. As an important means of achieving precision extrusion, efforts should be made to develop and research melt gear pumps. This is particularly important for industries that rely on extrusion for manufacturing products, including those with an extruder for sale.


Since China's extrusion machine products are closely linked to the market, they have the advantages of environmental protection, energy conservation, and high cost performance. For developed countries, exports are mainly concentrated in the low- to mid-range markets. This part of consumer demand is rigid. Therefore, the extrusion machine industry still has considerable market space for development.


Overall, China's extruder product export growth will show steady progress. From a domestic perspective, China is still in a phase of deepening development in industrialization, informationization, urbanization, marketization, and internationalization, and is still in an important strategic opportunity period for development. This will also provide inexhaustible development power for the extruder industry. Finally, the market’s recovery has brought confidence to extruder companies.
