GOLF BALLS AND METHODS OF MANUFACTURING THE SAME

摘要

A method of manufacturing golf balls (25) that prevents the cover (22) from cracking due to thermal expansion of the core (20) during the cover (22) formation process is disclosed herein. The method includes the forming a cor e (20), with one or more optional boundary layers (21), and then pre-heating t he core (20) and any boundary layer (21) to generate volumetric thermal expansi on thereof. After the pre-heating, the cover (22) of the golf ball (25) is form ed over the core (20) and any boundary layer (21). The method of the present invention also decreases cover (22) molding cycle time for golf balls (25).< /SDOAB>
