The plastic extrusion process involves melting plastic material, forcing it into a die to shape it into a continuous profile, and then cutting it to length. The process is a good choice for applications that require a final product with a constant cross-section. The low cost and high production rates make it a popular manufacturing choice for products such as piping, plastic sheeting, weather stripping, wire insulation and adhesive tape–to mention just a few of the common plastic extruded products.

There are three basic types of plastic extrusion machinery :

1. Single Screw
2. Multiple Screw
3. Ram Extrudes

Single and multiple screw extruders are the most commonly used.
