Abstract
Melting of plastics in intermeshing co-rotating twin screw extruders is known to occur over very short barrel lengths. The melting phenomenon has been studied for both pellets and powder in a readily opened clam shell barrel. The melting mechanism is attributed mainly to the dissipation of the energy imparted in interparticle friction as a consequence of the unique kneading action of this type extruder.Keywords
