Abstract
A method and apparatus for forming a core for a dual core golf ball is disclosed herein. A headblock is pressed against a mold tool wherein a hemispherical protrusion of the headblock compresses a slug within a first hemispherical cavity to form a first half shell outer core component. An inner core sphere is placed within the first half shell outer core component. An upper section of the mold tool is assembled onto a lower section of the mold tool to place a second half shell outer core component within an upper hemispherical cavity over the inner core sphere within the first hemispherical cavity to form a dual core component for a golf ball.

A method for forming a dual core component for a golf ball, the method comprising:
- placing a slug within a hemispherical cavity of a plurality of hemispherical cavities of a lower section of a mold tool, the lower section comprising a temperature control platen positioned below the plurality of hemispherical cavities and a moving platen positioned below the temperature control platen;
- pressing a headblock against the mold tool wherein a hemispherical protrusion of a plurality of hemispherical protrusions of the headblock compresses the slug within the first hemispherical cavity to form a first half shell outer core component, the headblock comprising a temperature controlled platen for heating the headblock during the pressing step;
- placing an inner core sphere within the first half shell outer core component;
- assembling an upper section of the mold tool onto the lower section of the mold tool to place a second half shell outer core component within a second hemispherical cavity over the inner core sphere within the first hemispherical cavity;
- curing the dual core component in the assembled mold tool;
- and
- demolding the dual core component.
