The production line, with reference to the latest international technology, adopts intensive mixing of PVC, PP, and PE with wood flour and additives, efficient conical twin-screw extruder, and forced cooling system for extrusion. The produced wood-plastic sheets are widely used as wide door plates, wall panels, architectural templates, container floorings, and furniture plates because of green and eco-friendliness, moisture prevention, corrosion resistance, size holding, and recovery.
