Abstract

This study proposes a least-squares methodology to obtain the optimum time history of mold-wall temperature that, at the end of the process, produces an injection-molded part with minimum residual-stress distribution. The proposed methodology is tested using two examples; (a) design of unconstrained vitrification under zero pressure, and (b) design of constrained vitrification with non-zero holding pressure.
