WPC Wood-Plastic Composite Extrusion Screw Barrel

Heavy-Duty Screw Barrel Solutions for WPC Extrusion

Wood-plastic composite extrusion is a high-demand application because WPC formulations typically contain a large proportion of wood flour, mineral fillers, and additives. These materials can create significant abrasive wear and require stable feeding, strong mixing capability, and reliable temperature control.

PIPLL provides customized screw and barrel solutions for WPC extrusion lines. Our systems are designed to improve material conveying, plasticization stability, wear resistance, and service life in demanding WPC production environments.

Typical Applications

· WPC decking boards

· WPC wall panels

· WPC door frames

· WPC profiles

· WPC fencing and railings

· WPC outdoor flooring

· WPC furniture components

· WPC decorative boards

Key Processing Requirements

· Reliable feeding of wood flour and composite materials

· Strong mixing and homogenization

· Controlled shear and stable melt temperature

· High wear resistance

· Stable pressure for consistent profile dimensions

· Good venting capability when moisture or volatiles are present

· Long-term service life under abrasive conditions

PIPLL Screw Barrel Solutions

· Conical twin screw barrels for WPC profiles

· High-filling polymer screw barrels

· Bimetallic wear-resistant barrels

· Reinforced alloy screw designs

· Enlarged feed openings for improved material intake

· Customized mixing and compression sections

· Segmented or liner-sleeve barrel options for easier maintenance

· Replacement screw barrel sets for WPC extrusion equipment

For high-wear applications, PIPLL can recommend bimetallic alloy barrel linings and wear-resistant screw surfaces to help extend replacement intervals and reduce maintenance costs.
