This production line can produce PE, PP or PVC wood plastic profiled products, mainly used for pallets, packaging box boards, flooring, outdoor decorative materials, etc., with a wide range of applications. The amount of wood powder and plant fiber added is high (up to 50-75%); The equipment has strong adaptability Produce wood plastic products using specially designed screw barrels, molds, and extruder processing production processes. The extruder can be used for single-stage mixing and direct extrusion, or two-step extrusion after granulation, which saves energy and space, has high output, stable extrusion pressure, and a preheating feeder placed on the top of the main machine to extract most of the residual moisture in the wood powder, making the feeding section of the main machine more complete; Characteristics such as good plasticizing and mixing effect. The optimized screw design reduces shear and makes it difficult to cut wood fibers, allowing materials to stay evenly in the machine. The screw barrel is treated with bimetallic material, which is wear-resistant and corrosion-resistant, greatly extending its service life.
