Production flow for making plastic lumber:
1, plastic recycling: washing, crushing ,drying the PP/PE plastic wastage into flakes, the flakes shall be used for WPC production directly.
2, wood powder making: crushing, milling and drying the wheat straw into 80-100 mesh powder
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.
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.
