What is Extrusion of Plastic?
Plastic extrusion, often referred to as plasticating extrusion, is a continuous, high-volume manufacturing process in which a thermoplastic material is uniformly melted and then compressed to push it out of the shaping die in the form of powder, pellets, or granulates.

The plastic melt takes on the form of the die hole as it exits the extruder and goes through the die. Extrudate is the term for the extruded product.
