by using the Taguchi optimization method.
Considering the number of plastic injection molding process parameters,
an orthogonal array of L18 was used for conducting experiments.
The effects of resin viscosity and curing percentage having great influence on the quality and shape of products were also discussed.
S/N ratio and ANOVA were used to obtain the optimal PIM process parameters.
The statistical software MINITAB 14 was used for the robust design methodology based on the Taguchi method
