Optimization of Die casting process based on Taguchi approach

Abstract

Due to light weight and good formability; aluminium die casting plays avital role mainly in the automotive industry. In aluminium die castings, porosity is one of the prominent defects most frequently encountered. Porosity formation limits the use of die-cast parts in critical high strength application. In this research, the use of the Taguchi approach has been conceptualized to obtain optimal settings of the die casting parameters, in order to increase the Al-Si8Cu3Fe (EN AC-46500) aluminium alloy die casting quality and efficiency by reducing the porosity formation. The effects of the selected parameters on the porosity formation and the subsequent optimal setting of the parameters have been accomplished using Taguchi approach. The final results indicate that optimized parameters considerably affect the porosity formation in Al-Si8Cu3Fe aluminium alloy die castings.
