Abstract—In the previous study, the limits of contact width of 25A-size metal gasket for no leakage can be chosen. The optimized gasket shape can be developed by increasing of contact width. In this study, a 25A-size metal gasket shape was optimized based on contact width as design concept and considering plastic contact stress. The design of experimentation (DOE) Taguchi method is used to analyse the effect of each parameter design and predict optimal design of new 25A-size metal gasket. The L18 orthogonal array was concerned to design experimental matrix for seven factors with three levels. The optimum design is chosen due to assumption that the better sealing performances are desirable because of the large contact stress. The optimum gasket design is the model with OH = 3 mm, p1 = 3.5 mm, p2 = 4.5 mm, p3 = 4.5 mm, t = 1.8 mm, R = 1.5 mm and h = 0.3 mm.
