Plastic extrusion is a large number of manufacturing processes, in which raw materials are melted and form a continuous profile. Extrusion produces items such as pipes / pipes, weathering stripes, fences, deck railings, window frames, plastic films and sheets, thermoplastic coatings and wire insulation.
The plastic extrusion process starts from the plastic (particles, granules, flakes or powders) in the hopper into the barrel of the extruder. The material is gradually melted by rotating the screw and the mechanical energy produced by the heater arranged along the barrel. The molten polymer is then pressed into a mold which forms the polymer into a pipe that is hardened during cooling.
The raw material enters from the hopper into the cylinder, and under the action of the rotation of the screw, the loose body passes through the inner wall of the cylinder and the friction surface of the friction surface to the forward feed section while the loose solid convection is carried out in the forward direction; in the compressed part, the shallow and further pressure In fact, when heated in the cylinder and the friction between the screw and the inner wall of the cylinder, the material temperature rises and begins to melt and the compression portion ends. Homogenization of the material so that the material evenly, constant temperature, melting, forming after the nose, stereotypes to get the product.
