Abstract：The technology of titanium alloy investment die casting was studied and optimized, and the problem of poor surface quality of titanium alloy investment die casting was solved. The types of surface defects in titanium alloy investment die precision casting were analyzed, and the mechanism of defects was studied, experimental verification was carried out. The results show that the slurry temperature has an important influence on the shell quality and the surface quality of titanium alloy investment casting. The high surface quality titanium alloy investment casting can be obtained when the slurry temperature is 20~23 ℃.
