Die design by computer simulation has some advantages compared with the conventional method which has performed by designer's experiences and trials and errors. The die filling and solidification process of thixoforming process were simulated by MAGMAsoft/thixo module. First of all, thixoforming die design was applied to previously geometry shape. The value of pressure distribution shows high and uniform as the gate diameter is 18mm. Designed gating system considering the deformation of die and product was suggested by the filling simulation. Gate velocity(7.25m/s) of designed gating system shows that propriety to semi-solid metal working process and CAE results were in good agreement with experimental results.
