Abstract
AbstractThe 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 pressure profile can reduce the frozen‐in birefringence. The shape and the tendencies of the predicted birefringence profiles agree well with the experimental ones. This leads to the conclusion that the, model can be used to optimize the processing conditions to mold high‐quality products with minimum frozen‐in orientation.
