Abstract:
A method of applying a coating material to an outer dimpled surface of a golf ball, which method comprises:forming a first mold cavity between upper and lower mold dies, said first mold cavity configured and adapted for molding a golf ball;molding within said first mold cavity a golf ball having an outer dimpled surface under a first pressure greater than ambient pressure until the golf ball is sufficiently cured to receive a coating that will not substantially penetrate the outer dimpled surface of the ball;opening the first mold cavity and transferring the molded but uncoated golf ball to a second mold cavity;preparing an in-mold golf ball coating composition;introducing a sufficient amount of said coating composition into the second mold cavity between the outer dimpled surface of the golf ball and an inner surface of said second mold cavity to substantially surround and coat the outer surface of said golf ball;curing said coating composition to form a coated golf ball having at least one layer of said coating composition; andremoving said coated ball from the second mold cavity so as to produce a coated golf ball having a dimple pattern thereon.
