Extrusion of Plastics
Plastics extrusion manufacturing process which is used in mass production when handling high volumes. During the process, raw plastic is melted and shaped into a continuous profile. Plastics extrusion begins by feeding the plastic material, in the form of pellets, granules, flakes or powders, into the barrel of the extruder. The material is then melted and forced into a die. There are different types of moulds in exclusion, which lead to the formation of different shapes and products. The most common of these are blown film exclusion (for the manufacturing of shopping bags), sheet/film extrusion (for sheet plastic that can’t be blown), tubing extrusion (for PVC pipes), overjacketing extrusion (for the outer layer of a cable), Coextrusion (for blown film, overjacketing, tubing, sheet), and extrusion coating (to give an additional layer onto an existing rollstock of paper, foil or film). Items produced via extrusion are vast but include pipe/tubing, weather-stripping, fencing, deck railings, shopping bags, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.
