Plastic extrusion manufacturing
What can be made using plastic extrusion?
Extrusion moulding of plastics is used to make any long shape that has a constant cross section. Pipes, gutters, window sections and decorative trims can all be made using the process.

Which type of plastic materials can you extrude?
Typical plastic materials that are used in extrusion include but are not limited to: polyethylene(PE), polypropylene, acetal, acrylic, nylon(polyamides), polystyrene, polyvinyl chloride(PVC), acrylonitrile butadiene styrene(ABS) and polycarbonate.
How do plastic extrusion machines work?
Plastic extrusion works by melting, processing and re-melting a type of plastic referred to as thermoplastic resins. The resins generally come in a bead or pellet form which allows them to be used in the extrusion machinery. The beads come in a variety of grades and this allows them to be purchased in the grade required for a specific use.
Fundamentals of Extrusion - ASM International
Extrusion can be cold or hot, depending on the alloy and the method used. In hot extrusion, the billet is preheated to facilitate plastic defor-mation. Classification of Extrusion Processes The two basic types of extrusion are direct and indirect, which are commonly used in aluminum industries as shown in Fig. 1 and 6. Solid

types of plastic extrusion: screw extrusion and ram extrusion. A ram extruder is an extruder where, instead of extrusion screw, a ram or plunger is used and a plunger goes through a barrel and pushes out the material under pressure. The ram extruder was the earliest extruder to be used in the plastics industry.
