Simplified three-dimensional simulation of non-isothermal filling in metal injection moulding by the finite element method

The non-isothermal filling of a powder/binder mixture in metal injection moulding is simulated by the viscoplastic and the heat conduction finite element methods. Proposes a simplified three-dimensional scheme for the moulding of products with a non-uniform thickness distribution. The computing time for the simplified three-dimensional scheme is of the same order as that for two-dimensional problems. Deals with complex overlapping between the surfaces of the mixture, resulting from the occurrence of jetting during the moulding, by the use of a remeshing scheme. The material flow in metal injection moulding into a rectangular die with a linear thickness distribution is simulated. The jetting behaviour is remarkably influenced by the thickness distribution of the die..
