Die casting process optimization using Taguchi methods

This paper analyzes various significant process parameters of the die casting method of AlSi9Cu13 aluminum alloy. An attempt has been made to obtain optimal settings of the die casting parameters, in order to yield the optimum casting density of the AlSi9Cu13 aluminum alloy castings. The process parameters considered were: piston velocity (first and second stage), metal temperature, filling time and hydraulic pressure. The effects of the selected process parameters on the casting density and the subsequent optimal settings of the parameters have been accomplished using Taguchi's method. The results indicate that the selected parameters significantly affect the density of AlSi9Cu13 aluminum alloy castings. (C) 2002 Elsevier Science B.V. All rights reserved.
