Abstract
A golf ball has a core and a cover and, the cover includes at least one thin spherical layer with a thickness of not more than 1.5 mm. The thin layer is molded by injecting an injection molding material at a selected fill speed which is correlated to the melt flow rate of the molding material. The invention facilitates the mass production of golf balls having thin spherical cover layers of uniform thickness which offer potential for further improvements in ball performance.
