<p>A method and system for compression molding a dual core of a golf ball is disclosed. The method may include a first cycle in which a top mold plate, a middle mold plate, and a bottom mold plate may be used to compression mold concave shells. During the first cycle, the top mold plate and the bottom mold plate may be held at a first temperature T1 and the middle mold plate may be held at a second temperature T2. During the first cycle, the mold plates may be pressed together with a first pressure P1 for a first time t1. A second cycle may include compression molding the concave shells about a solid core. During the second cycle, the top mold plate and the bottom mold plate may be held at the first temperature T1 and pressed together with a second pressure P2 for a second time t2.</p> |
