Casting defects such as gas traps and oxide particles must be removed in the die-casting process in order to obtain good cast products. Experimental research is costly and time-consuming, so computer simulations are typically performed in advance and then compared to experimental results. In this paper, a magnesium alloy die-casting process for a thin-walled mobile phone housing with 0.4mm thickness was investigated. The study examined the effects of important parameters such as overflow geometry and injection speed on surface defect and solid fractions. The overflow shape and second plunger speed were determined by simulations and experiments using an actual manufacturing process. In addition, the simulations predicted in this study showed in good agreement with the experimental results. †(Received December 13, 2016; Accepted February 22, 2017)
