Taking complicated aluminum alloy diecastings as study object, the 3D and FDM model were built. The filling process, solidification process and air entrapment condition of the aluminum casting were shown by numerical simulation. Based on the simulation, the positions of defects were predicted. The results of simulation are in good accordance with the product. The corresponding improving measures were put forward.
