Abstract
Provided is a method for manufacturing an iron golf club head by forging a single round rod member with a pair of dies to form, as a single piece, a body and a neck into which a shaft is to be inserted. The method includes: a first step of heating the single round rod member into a heated material; a second step of placing the heated material in the pair of dies; and a third step of forging the heated material placed in the pair of dies. In the third step, the heated material is prevented from flowing out from parting surfaces of the respective dies at a sole side of the body in the pair of dies, and the heated material blocked at the sole side in the pair of dies flows toward each of a toe of the body and the neck in the pair of dies.
