A Model To Predict The Residual Layer Thickness In The Injection Molding Process
MetadataShow full item record
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.
