This paper discusses the study and examined effect of die casting process parameters on porosity in aluminium alloy SAE 308 by using Taguchi method. In any die casting industry porosity is a very serious problem faced by production department and also being an invisible defect it is not identified visually in running production. It is shown in this work that die casting parameters which are related with machine such as first phase speed, second phase speed, first phase length and injection pressure all have significant influence on porosity level. The quality assessment of the die casting part was based on porosity measurement. The experiment have been performed as per the combination of levels of different process parameters suggested by L9 orthogonal array and conformation experiments have been performed to validate the optimum levels of different parameters
