  • Golf ball mold preparation technique and coating system
    Patent number: 6033724
    Abstract: A coating system and method for a golf ball injection mold having a land area and a patterned wall defining a hemispherical cavity is characterized by the application of a primer and a fluoropolymer top coat layer at least the patterned wall. The combined thickness of the coatings is no greater than 0.0007 inches. Owing to the thin coating, a golf ball molded in the cavity is easily ejected therefrom.

  • Game ball mold preparation technique and coating system
    Patent number: 5827567
    Abstract: Disclosed herein is a method of preparing a game ball mold cavity for application of a coating system. A dual region coating system for a game ball mold and a coating application method also are disclosed. The mold preparation method provides for a longer use of a game ball mold than results when conventional mold preparation techniques are used. The dual region coating system comprises a fluorocarbon polymer in the hemispherical opening of the mold cavity, and a metal, such as nickel, impregnated with a fluorocarbon polymer on the land area. The dual region coating system of the invention is particularly useful for making golf ball cores containing zinc-diacrylate and/or zinc dimethacrylate, as these materials tend to adhere to the walls of a mold cavity.
