CAST EXTRUSION
To extrude a thermoplastic polymer, granules are fed into a heat-regulated cylinder inside which an endless screw is turning. Due to the combined effect of the kneading action and heat, the granules are turned into a homogenous mix looking like a paste which is then given the desired shape by the die.
