Abstract

The warpage in a glass fiber-reinforced polyamide molded part caused by the sharp corner effect and differential shrinkage could be effectively reduced by optimizing the injection process parameters using numerical simulations. The results showed that adopting a three-gate injection method could effectively minimize the warpage caused by the sharp corner effect by more than 66% due to better fiber orientation and compensation of the shrinkage deviations. Simple equations were used to obtain the optimized packing profile, and the overall warpage could be reduced by more than 43%.
