Abstract

A method of die-casting a die-cast article (220, 426) having at least one of an inner circumferential surface and an outer circumferential surface, whose cross sectional shape is a circle, the die-casting article being formed with a die-casting apparatus having a mold cavity (236, 430) therein and a molding portion (250; 410) for forming one of the inner and outer circumferential surfaces of the die-cast article, the method being characterized by comprising the steps of: introducing a molten metal into the mold cavity; and separating the die-cast article and the molding portion from each other while the die-cast article and the molding portion are rotated relative to each other, after the molten metal has solidified into the die-cast article. A die-casting apparatus for practicing the method is also disclosed.
