<p>The process comprises forming a pre-molded center (13), molding two substantially hemispherical shells (26) having substantially hemispherical cavities, shaping the shells in a press having a top mold (101) and bottom mold (102), each with cavities concaving toward each other and a center plate (103) having top and bottom protrusions (107). The shells (26) are placed in the cavities of the bottom mold (102) and the protrusions of the center plate (103). The three parts of the press are aligned and closed as the press is heated. The center plate (103) is removed from the press with the shells (26) and the press is again closed and heated forming a golf ball core.</p> |
