section of a screw extruder of thermoplastic polymers - Students, Britannica Kids

Longitudinal section of a screw extruder of thermoplastic polymers. Plastic pellets are fed from a hopper into the barrel of the extruder, where the pellets are gradually melted by mechanical energy generated by a turning screw and by heaters arranged along the barrel. The molten polymer is forced through a die, which shapes the extrudate into products such as the examples shown.
