Abstract: A method for manufacturing an aluminum alloy rod head, wherein an aluminum alloy material is placed in molds of a panel, an upper cover, and a bottom plate; and then the molds are mold-cast to be formed as casings. The inner surfaces of the casings are installed with transversal enhancing bodies and longitudinal enhancing bodies. Therefore, the weight can be controlled easily and the ratio of the thickness thereof is also controlled easily. Moreover, the mold can be removed conveniently. Then, the connections of the casings are welded to be formed as a super large (above 330CC) rod head.
