The gating system of a cylindrical magnesium casting has been designed by using multiple objective optimization and Taguchi method. Mold filling and solidification processes were simulated by using MAGMASOFT®. The simulation results indicate that the gating system design has a significant effect on the quality of magnesium castings. In an effort to obtain the optimal design of gating system, the signal-to-noise (S/N) ratio was used to analyze the effect of various gating designs on cavity filling and casting quality by using a weighting method based on the design of an orthogonal array. Four gating system parameters, namely, ingate height, ingate width, runner height, runner width, were optimized with a consideration of multiple objective criteria including filling velocity, shrinkage porosity and product yield.
