This article introduces the basic principles of twin screw extrusion of plastics, including Mechanical principles，Thermal principle，Deceleration principle，The feed acts as a coolant，In the feed zone, sticks to the barrel & slides onto the screw，Materials cost the most，Energy costs are relatively unimportant，The pressure at the end of the screw is very important，Output = displacement of last thread +/- pressure flow and leakage，Shear rate plays a major role in viscosity， and The motor is opposed to the barrel these aspects.

The difference between twin screw extruder and single screw extruder is mainly reflected in the following two aspects.
