Effects of processing parameters on mechanical properties of squeezing casting ADC12 alloy were investigated.Through simulating squeezing casting process of door inner panel with the help of a CAE software

distribution of temperature field during filling process was presented at different pouring temperatures and mold temperatures.Based on the simulation results

two sets of processing parameters were designed to squeeze door inner panel for automobile

and door inner panel was produced successfully.Evaluation of aluminum panel quality was carried out in term of tensile testing

metallographic observation

environmental scanning electron microscope（ESEM） and auger electron spectrometry.It is found that the door inner panel with a relatively high mechanical properties and good surface quality as well as fine quiaxed primary Al phase can be obtained with pouring at 730 ℃ and pressure of 27 MPa as well as mold temperature of 310 ℃.
