Abstract

The disclosure provides a method of making a golf ball with a reduced gate defect. The method may include using a mold that has a mold cavity with a mold chamber with a surface and a parting edge disposed along the perimeter of mold chamber. At least one gate may be disposed on the parting edge to provide a path for a cover material to be injected into the mold chamber. The gate may include a flat middle surface connected by a first side surface and a second side surface disposed opposite the first side surface. A round having a radius of curvature ranging from about 0.2 mm to about 0.5 mm may be disposed along a middle gate edge of middle surface and/or a side gate edge of one of the first side surface and the second side surface.
