Yongte WPC Decking Co-extrusion Line | CE Certified Recycled PP PE Solution

Yongte WPC decking co-extrusion line is a specialized manufacturing system used to produce wood-plastic composite (WPC) decking boards. It involves a co-extrusion process where two or more layers of materials are extruded simultaneously to form a single product. Typically, this includes an inner core made from a mixture of wood fibers and plastic (such as polyethylene or polypropylene) for structural strength, and an outer cap layer that provides enhanced durability, UV resistance, and aesthetic appeal. This technology improves product quality by allowing customization of surface properties while maintaining cost-efficiency and sustainability through the use of recycled materials.

Technical Specifications

Equipment and Pictures of Yongte WPC decking co-extrusion line:

1, Conical twin-screw extruder: main extruder for melting and shaping the WPC core materials

specifically designed to handle the unique characteristics of WPC raw materials. Tapered screws with varying diameter along the barrel. the two screws rotate in opposite direction;provide efficient melting and excellent mixing with a relatively compact design; good for processing challenging materials.

2, Co-extruder: for plastization surface layer material

single screw extruder with drying hopper and metering feeding to ensure the co-extrusion material will be feeded and extruded uniform

3, Co-extrusion die and mold: for ABA multi-layer

specially designed co-extrusion die and mold for WPC production with uniform flow.

4, Online 3D embossing equipment: for wooden pattern deep embossing

it is installed directly after extrusion die, allowing embossing immediately while the material surface is soft and moldable. Utilizes textured rollers engraved or laser-etched with 3D patterns (e.g., wood grain, stone, fabric textures) that press onto the material surface.

5, Calibration and cooling systems : fast shaping system

6 meter length calibration table made by stainless steel which can ensure the WPC products can be cooled fast with good sizing.

6, haul-off units for pulling the profile: ensure continously stably production 

double caterpillar haul-off with tyre texture rubber blocks, drived by servo motor with double step gearbox.

7, Auto cutting machine: for length cutting

automatic cutter with diamond cutting blade to ensure smooth cutting section without chips, dust collection system ensure no pollution.

8, Electricity control system: Innovated system with high quality

high quality electric parts, such as ABB inverter, Siemens PLC control, Omron temperature controller, Siemens contractors.

Core Advantages of WPC Decking Co-extrusion Line

1. Dual-Layer Co-extrusion Technology: Superior Performance & Aesthetics

• Structural Design: Adopts advanced twin-screw co-extrusion system—the surface layer uses virgin PP/PE (or recycled high-grade plastic) with UV stabilizers and wear-resistant additives (hardness ≥65D), ensuring outdoor durability (anti-fading, anti-scratch, anti-slip); the core layer uses 60-70% recycled PP/PE + 80-100 mesh wood powder, balancing cost and environmental friendliness.

• Customizable Finish: Supports online embossing for wood-grain, stone-grain, or matte textures—no need for secondary painting, reducing production steps and costs. The finished decking mimics natural wood appearance while avoiding warping, rotting, or insect damage.

2. Eco-Friendly & Cost-Saving: Recycled Material Focus

• Raw Material Flexibility: Specializes in processing recycled PP/PE plastic waste (waste films, bottles, industrial scrap) and biomass fillers (wood powder, rice husk, straw). Reduces raw material costs by 30-40% compared to pure virgin plastic production, while diverting plastic waste from landfills—aligning with EU RoHS and US EPA standards.

• Low Carbon Footprint: The production process emits 50% less greenhouse gas than traditional wood flooring manufacturing, helping clients access eco-conscious markets (Europe, North America, Southeast Asia).

3. High Efficiency & Precision Control

• Adjustable Capacity: 100-300 kg/h output, supporting 24/7 continuous operation with a failure rate ≤1%—suitable for small-batch customization or large-scale mass production.

• Intelligent Automation: Equipped with PLC touchscreen control + PID precision temperature regulation (±1℃) for the co-extruder and mold. Segmented heating zones (150-180℃) ensure uniform plasticization, avoiding material carbonization or under-molding.

• Energy-Saving Innovation: Frequency conversion motor and heat insulation technology reduce energy consumption by 15-20% versus conventional co-extrusion lines. Quick mold change (≤1 hour) supports flexible product switching.

4. Turnkey Service & Global Compliance

• Complete Production Chain: Provides a one-stop solution from raw material processing to finished product

• Full-Service Support: Includes on-site installation, commissioning, operator training (3-5 days), and 1-year free maintenance. Core components (screw, barrel, motor) come with a 3-year warranty.

• International Certifications: CE certification and SGS-approved, ensuring seamless import to Europe, North America, Vietnam, India, and the Middle East.
