The state-of-the-art is presented for composite modeling of counter-rotating twin screw extrusion of polymeric materials. The closely intermeshing screw configuration is considered. A new approach for composite modeling of counter-rotating twin screw extrusion is discussed. This approach is based on the three dimensional nonNewtonian FEM simulation of flow in an intermeshing modular counter-rotating twin screw extruder. Some experimental and theoretical results of the study are presented. The polymer melting behaviour and degree of filling of the screw channel during the process, as well as the pressure and temperature developments are discussed.
