Abstract
A free casting method according to the present invention includes, a lead-out step for leading out molten metal from a lead-out area provided in a source of supply, e.g. a surface level of the molten metal, to retain the molten metal temporarily by surface films generated on an outer surface, and a forming step for obtaining a formed body by solidifying retained molten metal led out along a set passage depending on a desired casting shape, wherein the retained molten metal is solidified after being formed into the desired casting shape by applying an external force thereto at positions between an unrestrained root portion of the retained molten metal in vicinity of the surface level of the molten metal and a solidification interface defined as a boundary between the retained molten metal and the formed body in the forming step.
