The non-isothermal filling of a powder/binder mixture in metal injection molding is simulated by the viscoplastic and the heat conduction finite element methods. For the molding of products with a nonuniform thickness distribution, a simplified three-dimensional scheme is proposed. The computing time for the simplified three-dimensional scheme is of the same order as that for two-dimensional problems. Complex overlapping between the surfaces of the mixture due to the occurrence of jetting during the molding is dealt with by the use of a remeshing scheme. Material flow in metal injection molding into a rectangular die with a linear thickness distribution is simulated. The jetting behaviro is considerably influenced by the thickness distribution of the die.
