    • A process for making a golf ball with one or more deep dimples (118) is disclosed. The process utilizes a molding assembly for making a golf ball which includes a mold body that defines a molding cavity. The molding cavity is adapted to accommodate and preferably retain a golf ball core (112) during a molding operation of one or more layers (114) about the core (112). The molding assembly includes at least one material flow inlet, at least one material flow channel extending between and providing fluid communication with the material flow inlet and the molding cavity. At least one portion of the material flow channel has a plurality of bends and at least one branching intersection adapted to promote turbulence in a liquid flowing therethrough. The molding cavity includes at least one outwardly extending protrusion that forms a deep dimple (118) that extends through the cover (114) of the golf ball (110) to and/or into the underlying component of the golf ball (110) upon molding. The outwardly extending protrusion has a height greater than or equal to the thickness of the cover (114).
    • 公开了一种制造具有一个或多个深凹坑(118)的高尔夫球的方法。 该方法利用模制组件来制造高尔夫球,该高尔夫球包括限定模腔的模体。 在围绕芯部(112)的一个或多个层(114)的模制操作期间,模制腔适于容纳并优选地保持高尔夫球芯(112)。 模制组件包括至少一个材料流入口,在材料流入口和模腔之间延伸并提供流体连通的至少一个材料流动通道。 材料流动通道的至少一部分具有多个弯曲部和至少一个分支交叉点,其适于促进流过其中的液体中的湍流。 模制腔包括至少一个向外延伸的突起,其形成深度凹坑(118),其在成型时延伸穿过高尔夫球(110)的盖(114)和/或进入高尔夫球(110)的下面的部件中 。 向外延伸的突起的高度大于或等于盖(114)的厚度。
