Time：

2021-11-21

In China’s plastics machinery market, extruders are key processing equipment, and their prospects are highly promising. Over the past two years, the Chinese extruder market has made significant progress and achieved notable breakthroughs, as evidenced by: intensified development in emerging markets; further enhanced brand recognition; improved market competitiveness; and a substantial increase in the share of exports to developing countries.

In China’s plastics machinery market, extruders are key processing equipment, and their prospects are highly promising. Over the past two years, the Chinese extruder market has made significant progress and achieved notable breakthroughs, as evidenced by: intensified development in emerging markets, further enhanced brand recognition, improved market competitiveness, and a substantial increase in the share of exports to developing countries.

　　 Although China’s plastic extrusion machinery market has grown rapidly, the share of exports remains relatively low. As pressures from rising raw-material and energy costs mount, energy and material efficiency have become central concerns for the extrusion industry. Meanwhile, extrusion‑technology providers have developed a wide array of energy‑saving solutions, effectively addressing users’ needs for improved efficiency.

　　Adjusting the structure of China’s plastic extruders and expanding the industry’s growth potential. At present, the domestic plastic extruder sector faces challenges such as weak independent innovation capabilities, a limited range of high-end, customized, and specialized product lines, and low industry concentration. These issues prevent China’s plastic extruder industry from rapidly catching up with its international counterparts.

　　After long-term development, China’s plastic extrusion machinery industry has seen its international influence steadily grow, strengthened its ability to counter trade protectionism, and further enhanced its manufacturing technology and overall competitiveness. Consequently, the industry enjoys numerous favorable conditions for foreign trade exports. Given the close link between China’s plastic extrusion equipment and strategic emerging industries, coupled with advantages such as high efficiency, energy savings, and excellent cost‑performance, exports to developed countries are predominantly in the mid- to low‑end segments—segments characterized by rigid consumer demand. As a result, the extrusion machinery sector still has considerable market potential.

　　At present, China’s plastic extrusion machinery industry is undergoing shifts in the global market landscape, a trend underscored by a sharp decline in imports. Of course, this drop in imports does not necessarily reflect lower utilization of foreign equipment, as most international manufacturers have already relocated their production to China; meanwhile, exports are also decelerating.

　　 The high efficiency of plastic extruders is primarily reflected in their high output, low energy consumption, and reduced manufacturing costs. Functionally, screw extruders are not only used for the extrusion molding and compounding of polymeric materials but also find applications in industries such as food, feed, electrodes, explosives, construction materials, packaging, pulp, and ceramics. Furthermore, the combination of compounding and pelletizing with extrusion molding… The “one-step extrusion process” is also worth noting.

　　Today, modern electronic and computer‑controlled technologies are widely employed in plastic extruders in developed countries. Process parameters throughout the extrusion process—such as melt pressure and temperature, barrel temperatures at different zones, screw speeds of the main and feed screws, feed rate, formulation ratios of various raw materials, and motor current and voltage—are all managed via microcomputer‑based closed‑loop control. Some companies have implemented online remote monitoring, diagnostics, and control, enabling network‑based management of extrusion lines. This approach is highly beneficial for ensuring stable process conditions and enhancing product precision.
