Abstract
The present invention is directed to molded golf ball core constructions and methods for improving the molded golf ball core construction. The molded golf ball comprises a molded spherical core having a soft skin integral therewith, and a cover molded over the core. The soft skin is formed by controlling exothermic molding temperatures. A slug is placed in a mold cavity which is then closed. A steam set point is set, and steam is applied for a 25-30 minute period such that a maximum mold temperature exceeds the steam set point. In the alternative, the core surface may be softened by first immersing a slug in water prior to subjecting the slug to conventional molding conditions.
