Abstract
The traditional method of mathematical modeling of the die flows treats the die as a stand alone tool which is independent of the extrusion conditions which feed the polymer melt into the die. Here, we demonstrate that especially under the conditions where a breaker plate is not used the flow and the deformation which occur in the die are dependent on the prevailing velocity, stress and temperature conditions at the extruder. A finite element method based technique is used to solve the conservation equations using a mesh which covers both the die and the rotating conical screw tips of the extruder. The presented methodologies provide a more realistic representation of the thermo-mechanical history experienced by the polymer melt, emulsion or suspension in the die and thus provide better tools for the design and process engineers.
