Method of making dual core golf ball using novel center plate button and resulting improved golf ball

Abstract

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.
