Materials Used,Applications,Advantages About Plastic Extrusion

Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.

Materials Used

The different types of plastic materials that can be used in extrusion process are Polyethylene,Polypropylene (PP), Acetal, Acrylic, Nylon (Polyamides), Polystyrene, Polyvinyl Chloride(PVC), Acrylonitrile Butadiene Styrene (ABS) and Polycarbonate.

Applications

The extrusion process is used for manufacturing rods, plates and tubes, wire and cable coating,hose liners, hose mandrels, filaments, sheet, multilayer film, medical packaging and food packaging, etc.

Advantages

 High production volumes Relatively low cost as compared with other molding process Design flexibility Short lead times Coating of wire can be done to achieves desired properties Continuous part can be produced

Disadvantages:

 Limited complexity of parts Uniform cross section can only be produced
