Process for producing a golf ball with deep dimples
View Patent ↗An apparatus and related techniques for making a golf ball with deep dimples are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides deep dimples that extend through the cover layer and/or into a layer or component underneath are disclosed. At least one percent (1%), preferably about five percent (5%), of the dimples of the ball comprise deep dimples. The cover may be a single layer or include multiple layers. If the cover is a multi-layer cover, the dimples extend to or into at least the first inner cover layer, and may extend to or into two or more inner cover layers. If the cover is a single layer, the dimples extend to or into the core. The dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.
1. A process for forming a layer of a golf ball, the process comprising:
positioning a core or intermediate ball assembly in a cavity of a mold assembly;
introducing a flowable material into the cavity through a fan gate, the fan gate positioned on less than a hemisphere of the cavity; and
forming a cover layer from the flowable material over the core or intermediate ball assembly within the cavity, the cover layer having a plurality of deep dimples extending the length of the cover layer.
2. The process according to claim 1 further comprising mixing the flowable material within the mold assembly through a turbulence promoting portion, the turbulence promoting portion in flow communication with the fan gate through connection channel portion.
3. The process according to claim 1 wherein the flowable material is the reactant product of an isocyanate reactant and a polyol reactant.
