Plastic Extrusion Manufacturing is the process where a polymer or plastic material is fed into a heated cavity or cylinder and a hydraulic or pneumatic actuator or screw mechanism compresses and forces the molten plastic material through a tool die orifice. The plastic extruded material then cools and is further processed into the final part. Plastic extrusion parts and manufacturing is a high production process. Tooling costs for plastic extrusions are modest and generally considered inexpensive compared to metal extrusion.
Plastic extrusion materials maybe the following: ABS, acrylic, butyrate, fiberglass, nylon, polycarbonate, polyethylene (PE), polyethylene terepthalate glycol (PETG), polypropylene (PP), polyamide, polystyrene, PTFE, polyurethane or urethane, and PVC.
Standard industrial shapes created by plastic extrusion are films, sheet, rod or wire, cross sectional profiles, tubing, hose, pipes, and more. Plastic extrusion length are only limited to the manufacturing process machines capability. Very large area cross sections are possible by plastic extrusion manufacturing.
Custom extruded cross section shapes should have uniform wall section, and include generous radii at all surface intersections. Varying and high density cross sections should be avoided.
