This paper summary is based on the article [CORE VIABILITY SIMULATION FOR SALT CORE TECHNOLOGY IN HIGH-PRESSURE DIE CASTING] presented at the [International Journal of Metalcasting/Summer 2013] Abstract In high-pressure die casting (HPDC) undercuts can only be fabricated by using complex high-maintenance sliders. Until now, this technology has not been used for large-scale and cost-sensitive

Yung-Kuang Yang and Chorng-Jyh Tzeng Keywords: ANOVA, AZ91D, Die-casting, Taguchi method, Stress–strain. Introduction Magnesium and its alloys are becoming increasingly important as structural materials for applications in which weight reduction is critical, because of their low density and high stiffness-to-weight ratio. Popular applications include automotive, industrial, materials-handling, and aerospace equipment such as automotive pulleys, cog-tooth
