WPC Profile Co-extrusion Line

Yongte advanced WPC profile co-extrusion line integrates high output, energy efficiency, and reliability, empowering the creation of premium, long-lasting weatherproof WPC products from recycled materials. The machine efficiently melts and plasticizes wood-plastic granules (or fragments) using a conical twin-screw extruder, and a single screw extruder for the modified PE granules, before extruding them into a specialized co-extrusion mold to form the required size and shape. The design, featuring a barrel diameter that decreases 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 (achieving a final product density of 1.3 g/cm³) to ensure the strength of the final product. Additionally, the machine is equipped with a high-speed cooling and calibration table, a stable traction system, and automatic cutting equipment. The line can produce various WPC products by changing the mold.

Yongte WPC Profile Co-Extrusion Line addresses the limitations of insufficient weather resistance and uneven color caused by using recycled materials. By co-extruding a layer of high-quality modified PE onto the surface of the WPC core, we can create wood-plastic products with custom wood grain colors, which can withstand outdoor use for over 10 years.

Global WPC Project Cases

For instance, in a previous project for a Canadian customer, we provided a turnkey WPC production plant that utilized recycled plastic and PCB recycled fiberglass for the core WPC layer, paired with weather-resistant material for the surface layer. Similarly, in our WPC production project for an Indian client, the customer employed road waste mixed with various colored plastics for the core layer, complemented by an anti-aging co-extruded surface layer featuring custom colors. Additionally, our Romanian customer has adopted advanced WPC co-extrusion machine to replace traditional single-layer WPC, now offering products with over 10 years of warranty.
