Abstract：Taking a radar antenna base as an example, the digital without pattern casting precision forming process of complex thin-walled frame parts was studied. A reasonable pouring process was designed by adopting rain pouring system.The mold filling, solidification, shrinkage and porosity distribution of complex thin-walled frame parts were simulated and analyzed by Pro CAST casting simulation software. The results show that there are no casting defects in the castings obtained by pouring, which indicates that the process is reasonable and feasible.
