The standard deviation is constant in the progress of Powder Injection Filling, The setting value of the filling amount can modify the numerical rate. Since high level of the numerical rate can get the effect of reducing the material cost, it improves the productivity by permitting the possibility of the economical production. Consequently, this thesis analyzed and suggests the numerical model which consider the economical factors of the Powder Injection Shaping progress, and I try to reinforce the competitive powder of the domestic medicine manufacture industry which face the wave of globalism and evolutionism.
