JWELL provides advanced extrusion solutions for the production of PP/PE Wood-Plastic Composite (WPC) products, combining polymer processing technology with efficient compounding and profile extrusion systems. The complete production line is designed for manufacturing a wide range of high-quality WPC products, including outdoor decking, wall cladding, fencing, landscaping profiles and other composite profiles.
PP/PE WPC materials are typically produced from a combination of PE or PP resin, wood flour or natural fiber, recycled materials, and functional additives. With appropriate material formulation and processing technology, the final products can achieve excellent mechanical strength, weather resistance, moisture resistance and long service life.
For PP/PE WPC production, JWELL can provide a complete two-step extrusion solution.
In the first stage, the raw materials are accurately fed, mixed and compounded through a high-efficiency extrusion system to ensure uniform dispersion of wood flour, polymer and additives. The compounded material can then be processed into WPC pellets for stable storage and subsequent production.
In the second stage, the prepared WPC compound is fed into the profile extrusion line and processed through the extrusion die, calibration system, cooling section, haul-off unit and cutting equipment to produce finished WPC profiles with stable dimensions and consistent quality.
Typical Process:
PE/PP + Wood Flour + Additives
→ Mixing and Feeding
→ Compounding Extrusion
→ Pelletizing
→ WPC Compound
→ Profile Extrusion
→ Co-Extrusion (Optional)
→ Calibration and Cooling
→ Haul-Off and Cutting
→ Finished WPC Products
The JWELL PP/PE WPC extrusion line can be configured for the production of:
· WPC decking
· Co-extruded WPC decking
· WPC wall cladding
· WPC fencing
· WPC outdoor profiles
· WPC landscaping products
· Decorative composite profiles
· Customized PP/PE WPC products
For customers producing co-extruded WPC decking, the extrusion line can be designed with an additional co-extrusion system to apply a protective surface layer. This technology can help improve the product's surface appearance, weather resistance and durability.
The compounding system is designed to achieve efficient mixing and dispersion of polymer, wood flour and functional additives, helping to improve material consistency and processing stability.
The profile extrusion system is engineered to provide stable output and dimensional consistency, supporting continuous production of WPC profiles with different cross-sectional designs.
The production line can be customized according to the customer's product design, material formulation, capacity requirements and automation level.
The system can be configured for processing different PP/PE-based WPC formulations, including the use of virgin or recycled polymer materials, depending on the product requirements and formulation.
JWELL can provide a complete production solution covering material handling, mixing, compounding, pelletizing, profile extrusion, calibration, cooling, haul-off, cutting and downstream automation.
Different WPC products require different formulations, extrusion technologies and downstream equipment configurations. JWELL can provide customized extrusion solutions according to the customer's specific requirements, including:
· Product dimensions and profile design
· PP or PE material selection
· Wood flour content and formulation
· Required production capacity
· Co-extrusion requirements
· Surface treatment requirements
· Automation and downstream equipment configuration
With comprehensive experience in plastic extrusion technology and complete-line integration, JWELL offers a reliable solution for manufacturers looking to develop efficient and stable PP/PE WPC production capabilities.
