Mold-half

摘要

The present invention is an improved mold-half that is useful in forming golf ball covers or other layers. The mold-half is particularly useful for compression molding a thin polyurethane cover over a golf ball formed from a plurality of inner layers. The mold-half includes a cavity and a land area surrounding the cavity. The land area has an upper surface and at least one vent in fluid connection with the cavity via a chamber formed by a recessed circumferential ledge adjacent the cavity. The ledge controls the flow of excess layer material from the cavity to each vent.
