Plastic products are very common to see in our daily lifes:such as plastic pipes,bags and bottles.How to produce them?That is the answer-plastic extrusion production line.What is plastic extrusion?
Plastics extrusion is a high-volume manufacturing process ,and melting raw plastic that formed into a sustained products. Extrusion produces items such as pipe, weatherstripping, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.
This procedures begins by feeding plastic material (granules,pellets, flakes or powders) from a hopper into the barrel of the extruder. The material is melted by the mechanical energy generated by heaters and by turning screws arranged along the barrel gradually. The molten polymer is then pushed into a die, which shapes the polymer into a shape that hardens during cooling.
