    摘要： Methods of forming dual core golf ball constructions achieving consistent and repeatable concentricity by incorporating a pair of novel partially cured hemispherical shells produced using an inventive center plate button. The pair of resulting novel hemispherical shells may be collectively compression molded about and reliably center a spherical inner core there within due to the novel resulting centering features/structure provided on the inner surface of each partially cured hemispherical shell by the novel center plate button used to form same. Securing features/structure are thereby provided within/on inner surfaces of resulting partially cured hemispherical shells in order to prevent undesirable movement of the spherical inner core there within until the final compression molding step occurs.

    摘要： Golf ball having CoR of at least 0.700 and comprising: a substantially spherical subassembly having diameter of 1.3 inches or greater and compression of from about 15-60; and a thin outer layer having a compression molded thickness of about 0.015-0.055 inches and consisting of first and second hemispherical cups consisting of a polymer composition having a melt flow index at 190° C. under a 2.16-kg load of from about 0.8 g/10 min. to about 4 g/10 min. and having a cup thickness ratio of from about 1.10 to 1.70 as well as an inner surface that is sized, shaped and contoured to receive and conformally and adhesively mate onto and about the subassembly during compression molding such that the subassembly in the finished golf ball is substantially spherical and disposed concentrically within the thin outer layer. Also, the novel hemispherical cups and the method of making the golf ball.
