Harbin 150001, China）Abstract: Based on the mould features, the fluid mechanics models were founded. Integrating with the finite element method, the hydro-mechanical deep drawing of alumite LF6 was simulated. The alumite LF6 was formed by hydro-mechanical deep drawing, and the reasonable process parameters were obtained.
