A method for manufacturing a low-density steel wooden golf head solves the difficulty in reducing the thickness of a conventional wooden golf head. The method includes placing a shell mold having a crucible portion and a cavity portion in communication with the crucible portion on a rotary table, placing a metal ingot into the crucible portion, followed by melting the metal ingot in molten metal in a vacuum environment, rotating the rotary table to cause the molten metal to flow into the cavity portion under a centrifugal force, gradually slowing down the rotary table after the molten metal cools and solidifies, destroying the shell mold to obtain a casting including a cast product portion, and separating the cast product portion from the casting to obtain a casting product of a wooden golf head having a density of 6.5-7.6 g/cm3 and a minimum thickness of 0.4-0.6 mm.
