PURPOSE:To obtain a casting product of high quality in a stable by casting the molten metal of a rare earth metal in a specific height into the mold forcibly cooling the bottom face. CONSTITUTION:The bottom face of a mold is made of the structure capable of forced cooling, the liquid cooling by water, oil, etc., is usually used and in the case of water cooling a cooling water 5 is sufficiently flowed for cooling. The height of the side face frame 2 of the mold can optionally be selected by the thickness of the necessary casting product. The molten metal of a rare earth metal is cast into this forcibly cooled mold so as to become of the height less than 1/2 length of the longest line part dividing the bottom face. The casting product of high quality is obtd. in stable.
