This article describes a general mathematical model summarized in the form of a computer program for the plasticating extruder. The model combines features of the metering-zone model previously published, the melting-zone model described in paper No. I of this series, and a feed-zone model based on an extension of known theories. It is based on theoretical models for each zone unified and improved by non-linear estimation to accurately describe the extrusion experiments.The mathematical model predicts temperature, pressure, and melt channel width profiles of the plastic being processed in the plasticating extruder as a function of design and operating variables of the machine. It enables for the first time the design of the whole machine based on temperature and pressure profiles, including new combinations of cylindrical and tapered roots.
