| Abstract: | A suitable rheology model for real feedstock was created through the comparison of therheological behaviors of Bingham and pseudoplastic fluids and feedstock. The one-dimension-al flow of feedstock was analysed to establish the governing equations which would be solvedto obtain the temperature,pressure, flow rate and shear rate profiles of feedstock in moldcavity and the solution procedure was also represented in this paper. |

| Keywords: | feedstock rheology one-dimensional flow |
