This paper is related to the parametric identification and optimization of the injection moulding and sintering stage of the Metal Injection Moulding process. The injection stage is described using a biphasic flow formulation, whereas the sintering mechanism by solid state diffusion is accounted through a viscoplastic type material model. The accuracy of the numerical results of the injection moulding or sintering stages is strongly dependent on the identification of physical parameters entering in the models. In this paper one propose to combine the optimization of the injection moulding stage with the parametric identification of the sintering stage in order to determine the size of the mould cavities in order to get components without defects and with the appropriate resulting geometrical sizes and mechanical properties.
