Golf ball molds and related systems

摘要

Golf balls and systems for applying one or more polymer layers to a golf ball construct are disclosed. As but one example of disclosed systems, a method of forming a golf ball construct includes positioning a core or mantle portion of a golf ball in a cavity, opening a valve gate adjacent the cavity to cause viscous polymer to flow through the valve gate, into a short runner and into one or more radial runners that at least partially surround a circumference of the cavity. The polymer layer is allowed to solidify to form a solidified polymer layer, and the golf ball construct is removed from the mold cavity.

主权项

1. An injection mold for manufacturing golf balls, comprising:
a first substantially spherical cavity region, a first radial runner and gate system that at least partially surrounds a circumference of the first spherical cavity region; and a first short runner extending directly from a first valve gate to the first radial runner and gate system, the first short runner having a length of less than 0.5 inches defined by a distance between the first valve gate and the first radial runner and gate system, wherein the first valve gate is positioned between a source of viscous polymer and the first short runner, such that a molded construct formed by the injection mold terminates at the first valve gate.
