Numerical Simulation of Die Casting for Semi-Solid Aluminium Alloy and its Mould Research

Abstract

With consideration of the viscosity of semi-solid aluminum alloy slurry and the mold filling characteristics in die casting, the die-casting mould for semi-solid aluminum alloy has been designed and manufactured on the basis of the standard samples. The process of mold filling and solidification of semi-solid aluminum alloy in die casting was simulated by using ProCAST software. With combination of simulation results with die casting experimental data, the results indicate that the influence of heating system of the mould and cross section of ingate for the mould on flowing of semi-solid aluminum alloy in mould cavity is important in this work.
