Filling and solidification process of low pressure casting of thin-walled aluminum alloy water-cooled shells is a very complex process. In order to reduce the trial production cost, Any Casting software was used to simulate and analyze the pressure change and filling time in the filling process so that the influence of process factors on the filling and solidification was studied, and the defects such as insufficient filling and dispersed shrinkage were forecast under the condition of existence of spiral sand core. Results showed that adjusting reasonably process parameters such as pressure, pressurization speed and mold temperature could improve the quality of the water-cooled shells and stabilize the production.
