Dual core golf ball incorporating a solid spherical inner core component that is immovably centered within three outer core compression moldable parts and method of making same

Abstract

Dual core golf ball constructions achieving consistent and repeatable concentricity by incorporating/using an assembly of dual core components comprising a solid spherical inner core component and three outer core components that are collectively compression molded about the solid spherical inner core component to create an outer core layer thereabout. The three outer core components include a first half-shell, a second half-shell; and a ring-shaped securing plate such that the solid spherical inner core component is immovably centered within the outer core layer. Each of the first half-shell, the ring-shaped securing plate, and the second half-shell is comprised of the same rubber composition(s) and possess strong cohesive and adhesive bonds at parting lines between the three molded assembly parts and collectively create an outer core layer having one or more uniform property profile, such as a hardness gradient throughout, without interruption at parting lines between the three outer core components.
