A mathematical link is created between green body mass homogeneity and sintered component dimensional scatter. In the light of the model, data from die pressed and injection moulded powders are analysed for green mass variations and sintered size variations. The model provides guidelines for assessing research needs for process control, green body inspection and computer simulation with respect to dimensional tolerance goals.
