Polymer Single Screw Extrusion with Metered Feeding

The state-of-the-art is presented for composite modeling of single screw extrusion of polymeric materials. The flood mode of feeding and metered mode of feeding are considered. A new inverse approach of composite modeling for metered fed single screw extrusion is discussed. 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 development are discussed.
