Abstract

In this paper, the progresses made in modeling and simulating the die-casting of semi-solid metals are reported. An empirical rheological model of Sn-15%Pb is formulated based on experimental measurements of viscosity over a wide range of processing conditions using a coaxial-cylinder rheometer. Also, a new control-volume finite element procedure, called the Net-Inflow method, is proposed to simulate the mold-filling process in thin cavities. The free-surface position is determined iteratively with the velocity and pressure by satisfying all of the conservation equations and the free-surface boundary conditions simultaneously. The Net-Inflow method can be applied in complicated planar thin cavities with either negligible or significant inertial effect. The filling patterns of glycerin and water in a rectangular thin cavity are predicted and compared with other numerical solution and experimental observation.
