Abstract

The velocity field and pressure field were calculated by the projection method.Modeling of the filling process was established by the finite differential method through considering plunger movement based on the feature of squeezing casting

and filling process in squeezing casting was visualized.Pure aluminum parts were produced by squeezing casting to verify the availability of the modeling.The simulated results are well agreement with the experimental ones.
