Abstract
A method for manufacturing a golf ball in which the eccentricity of an inner core of the golf ball is greatly reduced. The method includes the steps of providing a mold which defines a mold cavity, positioning a vulcanized inner core in the mold cavity so as to define a shell space between the inner core and an inner surface of the mold cavity, introducing an unvulcanized rubber material into the shell space so that a layer of unvulcanized rubber covers the inner core, forming an intermediate product, removing the intermediate product from the mold, placing the intermediate product into a vulcanization mold cavity containing a dimple-forming interior surface and vulcanizing the layer of unvulcanized rubber and forming dimples in the rubber material during vulcanization.
