Abstract
The invention provides a process for manufacturing a golf ball, particularly a multi-layer golf ball. The process comprises forming a pre-molded center, molding two substantially hemispherical shells having substantially hemi spherical cavities, shaping the shells in a press having a top mold and a bottom mold, each with cavities concaving toward each other and a center plate having top and bottom protrusions. The shells are placed in the cavities of the bottom mold and the protrusions of the center plate. The three parts of the press are aligned and closed as the press is heated to a temperature below the cure activation temperature of the shell material. The center plate is then removed from the press with the shells in the cavities of the top and bottom mold. as ball center is inserted between the shells and the press is again closed and heated to a second temperature, above the cure activation temperature, fusing the shells around the center and forming a golf ball core. A cover is thereafter formed over the core either through compression or injection molding.
