WPC extrusion line , with new process of co extrusion in 2024, is mainly used to produce the hollow or solid wood plastic composite profiles with two or three kinds of WPC material mixture from wood powder, HDPE plastic and processing additives. By the WPC and WPC co extrusion technology, the WPC plants can use cheap WPC materials for inner layer extrusion of WPC profiles, and high quality WPC mixture mateiral for extruding the outer layer of WPC profiles, but the required material quantity is less for outer layer of WPC. Based on this WPC WPC co extrusion process, the WPC extrusion line can bring the following properties for the WPC plants: 1, save material cost for WPC profile extrusion. 2, improve the WPC quality with less cost, such as better weather resistance. 3, incease the skin affinity of WPC profiles especially for the deckings, benches and pergola project, etc. With different WPC molds to work on the WPC extrusion line, kinds of WPC products can be produced with ...
