The present invention provides a golf ball and a method for making the ball. Two cups are molded from an elastomer separately from a center. In one embodiment of the method, the cups are molded on both sides of a center mold plate with hemispherical protrusions. The protrusions force the elastomer cup material into cavities in outer mold plates on either side of the center mold plate, thus forming cups with cavities. The solid or fluid-filled center is placed within the cup cavities, and the cups are joined, preferably by raising the temperature of the mold above the cure activation temperature of the cup material. In some embodiments of the cups, the cups can be formed with non-planar mating surfaces that mesh with each other. The non-planar mating surfaces preferably have a pattern that is symmetrical about the cavities, such as concentric ridges or a tongue and a groove. |
