Abstract:
A method of forming a golf ball having interfacial adhesion, said method comprising:(a) forming a first finely textured pattern on an interior surface of a mold cavity, wherein said first pattern comprises a plurality of depressions having depths, with all of said depths being between about 2 and 15 mils, and having a draft angle of less than about 10.degree.;(b) introducing a core blend into said mold cavity having said first pattern;(c) forming a core having a finely textured surface profile integrally molded in the outer surface thereof, wherein said surface profile is a corresponding image of said pattern and comprises a plurality of peaks having heights, with all of said heights being between about 2 and 15 mils; and(d) applying a cover material to said textured core to form a cover surrounding said textured core such that the surface profile of said textured core promotes interfacial adhesion between the cover and said textured core.
