ABSTRACT:
Molding equipment and related techniques for forming a golf ball are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides one or more deep dimples that extend through the cover layer to and/or into a layer or component underneath are disclosed. 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 into two or more inner cover layers. If the cover is a single layer, the dimples extend to or into the core. The cover layer(s) may be formed from any material suitable for use as a cover, including, but not limited to, ionomers, non-ionomers and blends of ionomers and non-ionomers. 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. The molding equipment and related processes are particularly useful when forming the various layers by reaction injection molding.
