The results show that the surface of titanium alloy casing is glabrous and the dimension of form is precise and can be produced. The casing combined four pieces of soldering with forging, and it reduces the produce cost and makes the forging lighten. The flown line distribution of forging is logical, and the forging structure and capability are eligible.
