Abstract
The effects of the wall temperature on the residual layer thickness of the polymers are studied numerically in the filling process in the injection molding process. A lubrication approximation model is developed to furnish a semi-analytical solution. The shear viscous heating terms are neglected to simplify the governing equations. The Cross-WLF viscosity model is used to capture the residual layer. There is a good agreement between the results of the developed model and experiments.
