Therefore, to predict and control the type of casting defects and performance in the forming process is extremely necessary. As one of the effec-tive means of guiding production, the casting numerical simulation technology could help to optimize the casting process. However, since the forming defects are generally caused by the through process, including mold filling, solidification, and hot isostatic pressing process, the process simulations of separate studies have been unable to meet the requirements for titanium casting precision. Accordingly, aiming at precision castings of aerospace titanium casing, the numerical simulations of the through process were conducted. And the simulation results of hot isostatic pressing process were validated by actual experiments result. The results show that the displacement difference was substantially equal to the difference between the diameter of the hole displacement, which verifies the effectiveness of the guidance and numerical simulation methods. And it also provides the basis for numerical simulation of forming process of the subsequent casting.KEYWORDS: titanium, filling, solidification, hot isostatic pressing, through process, numerical simulation
