What is Wood Plastic Composite? How It was Made?
Wood plastic composite is a new class of composite materials in recent years. It is made of a unique blend of natural wood and plastic fibers. Sawdust, pulp, bamboo, peanut hulls, and unused woodworking materials, like bark, from a variety of projects, are combined with polyethylene, polypropylene, and polyvinyl chloride, etc. to form this new material WPC. Then by extrusion, molding, injection molding and other plastics processing, wood plastic composite is produced out in a variety of colors, shapes and sizes, and with different surface textures.
Depending on the processing method, WPCs can be formed into almost any shape and thus are used for a wide variety of applications, including windows, door frames, interior panels in cars, railings, fences, landscaping timbers, cladding and siding, park benches, molding and furniture.
PP/PE/PVC compounding with wood fiber up to 65%, color masterbatch and additives.
WPC granulating line
WPC granulating line is used to compound the different WPC materials together, with good degassing, enough plasticizing and blending by the twin screw structure, to ensure the final WPC profiles with fine texture on the section and uniform color on the surface.
For HDPE WPC or PP WPC plant, the WPC granulating line is a necessary unit.
WPC Product Manufacturing Processes
The manufacturing processes for wood-plastic composites are extrusion, injection molding, and compression molding or thermoforming (pressing).
