Abstract: This study discusses the Taguchi`s quality control technique, determining the optimum combination of design parameters of die casting process for optimisation in quality of aluminium alloy casting. Specifically the mechanisms of porosity formation and the AlSi9Cu3 aluminium alloy casting density in relation to die casting parameters have to be studied in detail. Through simple multifactor experiments in the foundry, controllable factors can be isolated to provide centring and variance control for process variables. The method is briefly explained and its application is demonstrated by the use of a die casting experiment in a foundry industry. Conclusively, the casting process is robust to uncontrollable factors (noise) selecting the optimum levels of process parameters with the target to illustrate practicality and ease of use by industry engineers and managers.
