Cold chamber die casting process is designed to achieve high dimensional accuracy by forcing molten metal under high pressure into reusable moulds called dies.The present research work is aimed at parametric optimization of process parameter in cold chamber die casting for an industrial component (crank case). Three controllable factors of the cold chamber die casting process (namely: 1st phase pressure , 2nd phase pressure and limit switch position) were studied at three levels each by Taguchi's parametric approach and single-response optimization was conducted to identify the main factors controlling surface hardness (SH), dimensional accuracy (Δd) and weight of cast component (W).
