Abstract
The present invention provides a method of forming a multi-layered core, particularly a multi-layered core for a golf ball, that provides improved centering of the golf ball center within the core, while allowing existing formulations to be used. The method includes heating the core material, molding it to form hemispherical shells, cooling the hemispherical shells, and assembling two hemispherical shells around a golf ball center to form a multi-layered core. The increased rigidity of the shells resulting from cooling them allows the use of existing core formulations while improving the centering of the golf ball center.
