Abstract: Abstract The numerical simulation of the injection molding process described in Part I is compared in the present paper with experimental results obtained with an instrumented test mold. Pressure and birefringence profiles are compared with corresponding predictions for an amorphous polymer. The influence of the melt temperature, the flow‐rate, and the packing pressure on the pressure profiles and the frozen‐in birefringence is investigated. It is demonstrated that the prescription of a specified packing pres…
