Abstract
A method of manufacturing golf balls having a core and a cover of at least one layer encasing the core includes, when molding the cover, blending a thermal antioxidant into the cover stock in a plurality of divided portions. This method is able to minimize deterioration and discoloration of the cover stock, enabling golf balls of stable quality to be obtained. In addition, it is able to facilitate the use of reclaimed material, enabling environmentally and economically efficient production to be carried out.
