The present invention includes forming a spherical inner core layer, forming two hemispherical shells in a compression mold, and assembling two hemispherical shells as outer core layers around the inner core layer, It relates to a golf ball manufacturing method. In addition, the golf ball manufacturing method of the present invention comprises the steps of curing two hemispherical shells to form an integral outer core layer by compression molding the two hemispherical shells around the inner core layer at a temperature that causes melting of the inner core layer. It may also include. |
