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 molding equipment provides one or more selectively positionable knock-out pins along the surface of the molding chamber. These pins are specially tailored such that subsequent to molding, the resulting voids are traditional or deep dimples. The molding equipment and related processes are particularly useful when forming the various layers by reaction injection molding.
