Abstract
An apparatus and related techniques for making a golf ball with deep dimples are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides deep dimples that extend through the cover layer and/or into a layer or component underneath are disclosed. At least one percent (1%), preferably about five percent (5%), of the dimples of the ball comprise deep dimples. The cover may be a single layer or include multiple layers. If the cover is a multi-layer cover, the dimples extend to or into at least the first inner cover layer, and may extend to or into two or more inner cover layers. If the cover is a single layer, the dimples extend to or into the core. The dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.

6. A process for forming a layer of a golf ball, the process comprising:
-
positioning a core or intermediate ball assembly in a cavity of a mold assembly;
introducing a flowable material into the cavity through a fan gate, the fan gate positioned on less than a hemisphere of the cavity; and
forming a layer from the flowable material over the core or intermediate ball assembly within the cavity. - View Dependent Claims (7, 8, 9)

10. A molding apparatus for forming a reaction injection molded cover of a golf ball, the mold apparatus comprising;
-
an assembly comprising a first mold half and a second mold half;
a cavity of the assembly, the cavity defined by a hemispherical first mold surface of the first mold half and a hemispherical second mold surface of the second mold half, each of the hemispherical second mold surface and the hemispherical second mold surface having at least two populations of outwardly extending projections that form a surface of a golf ball, the two populations of outwardly extending projections differing from each other by the height of outwardly extending projections;
a fan gate portion in flow communication with the cavity of the assembly;
a connection channel portion in flow communication with the fan gate portion; and
a turbulence promoting portion in flow communication with the connection channel portion.
