The process of Twin screw hot melt extrusion

The process of Twin screw hot melt extrusion
The hot-melt extrusion process is carried out by using an extruder, which is a barrel with a platform supporting two rotating screws that push substances down the barrel. An extruder is made up of four main components, as follows:

An opening/feeding port that is used to introduce substances to the barrel;  it might be continuously supplied with the substances by one or more external units
a process platform made up of the barrel and screw(s) that move and, where required, mix the substance
an orifice that shapes the substance as it exits the extruder

Auxiliary machines where the product is cooled, cut, and/or collected
