Improved injection molding methods and molds, for forming TPU layers, especially thin TPU covers, into golf ball constructions, and having improved number, shape and placement of both the injection gates and the cold slugs within the mold in order to minimize/eliminate damage to dimples strategically positioned close to the parting line of a mold in order to maximize aerodynamic properties of the resulting golf ball.

Injection molding method and mold

Golf ball methods and molds for quickly and efficiently eliminating air/gas from within a mold during golf ball manufacture and the improved golf balls resulting therefrom.

Methods and molds for molding golf balls incorporating a thermoplastic polyurethane cover

Golf ball methods and molds for quickly and efficiently eliminating air/gas from within a mold while better centering a subassembly in the mold during golf ball manufacture and the improved golf balls resulting therefrom.

Golf ball molds and methods for molding golf balls, particularly golf balls having thermoplastic polyurethane covers, are provided. The molds and methods are particularly suitable for manufacturing covers for golf balls. Multi-piece golf balls having inner cores, outer cores, inner covers, and intermediate layers can be made. Retractable pins are used for holding the golf ball within the mold, wherein each retractable pin has a primary vent section, secondary vent section, and tertiary vent section for removing air and other gasses from the interior spherical cavity of the mold.
