ABSTRACT:
An injection mold includes a pair of mold sections which are removably mated to define a spherical cavity by their concave surfaces, support pins disposed in the mold sections for movement into and out of the cavity, and gates connected to the cavity for feeding a cover molding material from an injection molding machine into the cavity. A golf ball having a core and a cover is prepared by supporting the core in the cavity by the support pins, and injecting the cover molding material between the core and the cavity-defining surface through the gates, thereby molding the cover around the core. The gates are oriented relative to the cavity such that the cover molding material is injected in a direction off the center of the core.
