Abstract：Aiming at the flow state of molten metal in injection chamber during aluminum alloy die casting process, the flow state, gas entrainment and gas-lock in in the injection chamber were simulated with using ProCast software under different process conditions designed based on the orthogonal test. The results show that the flow state of molten metal in injection chamber is different with different process parameters, among them punch velocity has biggest impact on the flow sate. With increasing punch velocity, the risk of gas entrainment increases significantly. The gas entrainment risk decreases with filling degree of injection chamber. The effect of injection chamber diameter, length and the molten metal temperature is not obvious.
