Abstract
The optimal process conditions of an injection molded polypropylenes dustpan were investigated to improve the part quality. A fractional factorial experiment was employed to screen the significant factors and main combinations among the numerous process parameters. And, with the consideration of interaction effects, an L27 orthogonal array based on the Taguchi method was conducted to determine the optimal process conditions. The results indicate that the melt temperature has the most remarkable influence on both the volume shrinkage and sink marks criterion weights. But the optimal process conditions and the order of influence are different for the two criterion weights.
