WPC Decking Extrusion Line

As leader manufacturer in China for advanced WPC decking extrusion line, Yongte provides integrated turnkey solutions for Wood Plastic Composite production lines. Our cutting-edge manufacturing equipment features intelligent automation, intuitive control panels, and streamlined labor requirements, achieving 15-20% energy efficiency improvements over conventional machinery. Through proprietary mechanical engineering and formulation optimization, our systems enable utilization of up to 70% wood flour content—reducing plastic composition to just 25%. This innovative approach enhances production throughput, lowers material expenses, and significantly improves the mechanical performance and dimensional stability of finished WPC products.

To address the challenges of global material cost volatility, Yongte has strategically developed a comprehensive portfolio of adaptive composite formulations and modular mechanical designs that enable WPC production from diverse waste streams. This innovative approach not only mitigates raw material cost risks but also aligns with circular economy principles by converting industrial and post-consumer waste into high-value building materials. Our technology ecosystem includes specialized extrusion systems tailored for various waste-to-WPC applications: textile-reinforced composite lines processing recycled clothing fibers blended with plastic matrices, PCB waste utilization systems that safely incorporate electronic scrap into structural profiles, sand-plastic composite equipment for producing weather-resistant decking materials, and recycled fiberglass hybrid systems that enhance product strength while diverting industrial waste from landfills. Each solution features adjustable processing parameters to accommodate variations in waste material quality, ensuring consistent output performance across different feedstock compositions.

Technical Parameters

WPC Decking Full Production Process

Comprehensive turnkey project service is key strength of Yongte factory. We integrate customized plastic recycling machines, wood powder machines, WPC granulation machines, WPC decking extrusion machines, auxiliary equipment, and intelligent control systems, providing clients with integrated solutions from raw material processing to finished products, ensuring equipment compatibility and process optimization.

1. Plastic Recycling Machine:	We supply plastic recycling equipment tailored to the customer's raw material. The entire range of optional functions includes plastic crushing, washing, granulation, and dewatering or drying functions.
2. Wood Powder Making Machine:	Depending on the size of the customer's wood material, we can equip various wood powder making machines, such as wood log chipping machines, wood chip crushing machines, wood sawdust grinding machines, and wood powder drying machines.
3. WPC Mixing Machine:	This machine is used for mixing wood powder, plastic material, and chemical additives according to our formulation. We equip a high-speed heating mixer to ensure the material is mixed uniformly and the chemicals are well blended.
4. WPC Granulation Machine:	The parallel twin-screw vented extruder, specifically designed for high-filler wood-plastic composites, efficiently combines wood flour (or other fillers) and plastic. This composite process not only mixes the materials superficially but also binds and plasticizes the molecules of the plastic and wood flour, ensuring the strength and quality of the final wood-plastic product. Yongte WPC granulation machines offer excellent gas venting, superior material composite plasticizing, high output, and low power consumption.
5. WPC Decking Extrusion Line:	The function of a WPC decking extrusion line is to efficiently melt and plasticize wood-plastic granules (or fragments) using a conical twin-screw extruder, and then extrude them into specialized wood-plastic molds to form the required size and shape. The design of the barrel diameter decreasing from large to small ensures not only the mixing effect of the material but also a stable melt pressure within the mold cavity, compressing the wood-plastic material (final product density reaches 1.3 g/cm³) to ensure the strength of the final product. The machine is also equipped with a high-speed cooling and calibration table, a stable traction system, and automatic cutting equipment. The line can also produce WPC wall panels, WPC fence panels, and WPC post products by changing the mold.
6. Co-extrusion Machine:	To address the shortcomings of insufficient weather resistance and uneven color caused by using recycled materials, we equip a co-extrusion process in wood-plastic composite production. By co-extruding a layer of high-quality modified PE on the surface of the WPC core, we can create various wood grain colors on the surface of the wood-plastic products, which can be used outdoors for more than 10 years.
7. Online 3D Embossing Equipment:	To give WPC decking a more realistic wood grain appearance and anti-slip effect, we have equipped an online 3D deep embossing machine. This equipment can be installed on the calibration table of the WPC extrusion line, creating a more realistic wood grain effect. The embossing roller is interchangeable for producing different wooden textures.
8. Sanding and Brushing Machine:	Do you know how the wood-like rough texture on the surface of WPC products is achieved? This is accomplished using Yongte's specially configured sanding and brushing machines. Depending on the desired roughness, we offer a variety of sanding and brushing machines with different configurations.

WPC Product Application

WPC wall cladding combines the texture and physical processing properties of wood—such (as being cuttable, sawable, and having strong nail-holding power—with the corrosion resistance of plastics, (including being insect-proof, mildew-proof, and waterproof. WPC wall cladding products are widely used in the construction industry.
