Since the casting process of large castings is complicated, the optimization of process parameters has a significant impact on product quality. In this paper, main technical parameters of male thread casting in screw expansion power machine were compared and analyzed with simulation analysis method and an applicable speed and temperature for male thread casting was obtained by mainly considering the entrapped air and the surface defect density. In general, the analysis methods provided herein, offers a viable way to optimize the quality of large machine components while casting. This can benefit the productivity and cost saving.
