SJSZ-65/132 CONICAL DOUBLE SCREW EXTRUDER is mainly used for extruding PVC material. Coordinated with the appropriate auxiliary machinery, it can produce many kinds of plastic products, PVC window/door profiles, wall panels, edge banding profile, ceiling board, water supply pipe, pelletes and so on.
PLASTIC MATERIAL ---TO--- DIFFERENT PRODUCTS
This process starts by feeding plastic material (pellets, granules, flakes or powders) from a hopper into the barrel of the extruder. The material is gradually melted by the mechanical energy generated by turning screws and by heaters arranged along the barrel. The melten polymer is then forced into a die, which shapes the polymer into a pipe that hardens during cooling.
