Abstract

A molten magnesium material is filled into a product section of a die. The molten magnesium material is cooled and solidified in the die, so that a molded product is formed. Subsequently, a thread-shaped pin is rotated, so that a female-thread forming section is drawn from the female-thread section of the molded product while the female-thread forming section is rotated. Thus, the female-thread section can be formed when the molded product is formed. A magnesium-alloy material is not apt to stick to a steel material used in the die compared with an aluminum-alloy material, so that the female-thread section can be steadily formed.
