Plastic extrusion is a continuous high volume manufacturing process in which a thermoplastic material is homogeneously melted and then forced out of the shaping die by means of pressure.
There are different types of extruder. Generally, extruders can be classified as continuous or discontinuous extruders.
A single screw extruder has different parts with the screw as the most important component.
In plastic extrusion, there are various types of die which can be used like T-die, fishtail die, coat hanger die, spiral mandrel die, crosshead die, etc.
Plastic extrusion has a wide range of applications including sheets, films, coatings, pipe, tubing, etc.
