Production Flow for Wood Plastic Composite WPC Decking Making Machine
•1, plastic recycling: washing, crushing ,drying the PP/PE plastic wastage into flakes, the flakes shall be used for WPC production directly.
(If you buy waste plastic flakes,no need this machine)
•2, wood wheat straw powder making: crushing, milling and drying the wheat straw into 80-100 mesh powder
(If you buy wood powder directly,no need this machine)
•3, material mixing: weighting and mixing all material together according to our formula by hot mixing machine
•4, WPC granulating: extrusion by parallel double screw extruder and do hot-pelletizing into WPC granules.
(If you buy granules ,no need 1-4 process and machines)
•5, WPC extrusion: extrusion by conical double screw extruder and molding in required size and shape with water cooling calibrating, online fixed length cutting.
•6, WPC surface design: embossing, brushing, or sanding on the surface to make different wooden grain feeling.
(We will provide the machines according your requirments)
