WPC (PP/PE+Wood) Parallel Twin-screw Pelletizing Line

Q1: What materials can be processed with this pelletizing line?

A1: This line is suitable for virgin or recycled PP and PE plastics mixed with wood powder, rice husk, bamboo fiber, or other natural fibers to produce WPC (Wood Plastic Composite) pellets.

Q2: What is the main advantage of using a parallel twin-screw extruder?

A2: The parallel twin-screw design provides excellent mixing, dispersion, and stable extrusion pressure, making it ideal for compounding high wood-content materials and achieving consistent pellet quality.

Q3: Can recycled plastics be used in this line?

A3: Yes. The system is designed to handle recycled PP or PE materials, helping to reduce production costs and promote sustainable manufacturing.

Q4: How is temperature controlled during the compounding process?

A4: The extruder adopts multi-zone precision temperature control, ensuring stable plasticization, preventing thermal degradation, and maintaining uniform product color and quality.

Q5: What are the benefits of this pelletizing line compared to traditional single-screw systems?

A5: Compared with single-screw extruders, the parallel twin-screw extruder provides better dispersion, higher output, and more uniform pellets, especially suitable for WPC materials with high filler content.

Q6: What type of final products can be made from the WPC pellets?

A6: The pellets can be used to produce WPC decking boards, wall cladding panels, decorative profiles, fencing, and outdoor furniture components.

Q7: Is the machine customizable?

A7: Yes. The system can be customized in screw size, pelletizing method, capacity, and automation level to meet different customer requirements.

Q8: How is the machine maintained for long-term stable operation?

A8: Regular cleaning of the screws and barrels, checking the wear parts, and maintaining proper temperature control will ensure stable performance and extended machine life.
