1. Modular plastic extruders: Modular production can accommodate diverse customer requirements, shorten new‑product development cycles, and help capture a larger market share. 2. High‑efficiency, multifunctional plastic extruders: Their efficiency is primarily reflected in high output, low energy consumption, and reduced manufacturing costs. In terms of functionality, screw‑type plastic extruders are already employed for extrusion molding and compounding of polymeric materials. 3. Large‑scale and precision‑oriented design: Scaling up plastic extruders can lower production costs, with clear advantages evident in large‑capacity twin‑screw pelletizing lines, blown‑film lines, and pipe‑extrusion lines. These represent key technological equipment required for national priority projects. 4. Intelligentization.

1. Modularization

Modular production of plastic extruders can accommodate diverse customer requirements, shorten the R&D cycle for new products, and help capture a larger market share.

2. High efficiency and multifunctionality

The high efficiency of plastic extruders is primarily reflected in their high output, low energy consumption, and reduced manufacturing costs. In terms of functionality, screw-type plastic extruders are already employed for the extrusion molding and compounding of polymeric materials.

3. Large-scale and high-precision

Scaling up plastic extruders can reduce production costs, with particularly significant advantages in large‑scale twin‑screw plastic pelletizing lines, film‑blowing lines, and pipe‑extrusion lines. Major technological equipment required for key national infrastructure projects.

4. Intelligence and Networking

In developed countries, plastic extruders have widely adopted modern electronic and computer control technologies to perform online monitoring of process parameters throughout the extrusion cycle—such as melt pressure and temperature, barrel temperatures at different zones, screw speeds of the main and feed screws, feed rate, raw-material blending ratios, and motor current and voltage—and to implement microcomputer‑based closed-loop control. This approach helps ensure stable processing conditions and enhances product precision.

Plastic extruders (main machines) can be paired with a wide range of auxiliary equipment for plastic molding—such as pipe, film, rod, monofilament, flat‑filament, strapping, mesh, sheet (plate), profile, pelletizing, and cable‑jacketing units—to form diverse plastic extrusion production lines that manufacture an array of plastic products. Consequently, plastic extrusion machinery remains, both today and in the future, one of the most widely used types of equipment in the plastics processing industry.
