China’s Plastic Extruder Industry Has Great Development


In China’s plastic machinery market, extruder is an important processing equipment. The development prospect is very optimistic. In the past two years, China’s plastic extruder market has made considerable progress and breakthroughs, as shown in the following: the expansion of the emerging markets for extruders, the brand awareness has further expanded, the market competitiveness has further improved, and the proportion of exports to emerging countries has increased. It will also be greatly improved.

Although China’s extruder market is developing rapidly, the proportion of extruder exports is still low. The ever-increasing pressure on raw material costs and energy costs has made energy saving and material saving the focus of the extrusion processing industry. At the same time, plastic extrusion machine suppliers can develop various energy-saving solutions from various perspectives to meet the energy-saving needs of users to the greatest extent.

China’s plastic machinery adjustment structure enhances the development space of the extruder industry. The current development status of the domestic plastic machinery industry is that such problems as low independent innovation capability, few high-end and personalized special varieties, and low industry concentration. The existence of these problems has caused Chinese plastic extrusion machine manufacturers to not catch up with foreign plastic machinery levels as soon as possible.

After long-term development, the international influence of China’s plastic machinery industry has been continuously improved, its ability to respond to trade protectionism has been strengthened, its manufacturing technology level and overall strength have been further improved. Therefore, China’s HDPE pipe production line has many favorable conditions for foreign trade exports. As China’s extruder products are closely linked to strategic new industries, they have the advantages of high efficiency, energy saving and high cost performance. Exports to developed countries are mainly low-end. This part of consumer demand is rigid. Therefore, extruder the development of the industry still has a large market space.

China is still in the stage of in-depth development of industrialization, informatization, urbanization, marketization, and internationalization, and is still in a period of important strategic opportunities for development, which will also provide an inexhaustible development momentum for the extruder industry. Finally, the recovery of the international market has brought confidence to extruder companies.

The high efficiency of plastic extruders is mainly reflected in high output, low energy consumption and low manufacturing costs. In terms of functions, screw extruders have been used not only for the extrusion molding and mixing of polymer materials, but also for food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics and other fields. In addition, the “one-step extrusion process” combining kneading granulation and extrusion molding processes into one is also worthy of attention.

Extruders in developed countries now generally use modern electronic and computer control technology. Process parameters such as melt pressure and temperature, body temperature of each section, main screw and feeding screw speed, and feeding amount are used for the entire extrusion process. The parameters of the various raw materials, the current and voltage of the motor are tested online and closed-loop control is used. Some companies have adopted online remote monitoring, diagnosis and control to carry out network control on extrusion molding production lines. This is extremely beneficial for ensuring the stability of process conditions and improving the accuracy of the product.
