Infrared heating method for creating cure gradients in golf balls and golf ball cores

Abstract

This invention is directed to a method for creating cure gradients in golf balls and golf ball cores by the application of high temperatures from infrared radiation. The hardness gradients are created in the outer skin wherein the outer 0.001 to 0.040 inches of the core has a different hardness than the rest of the core. The same hardness gradients can be applied to the outer skin of any intermediate or cover layers. The skin can either be harder or softer than the rest of the component. The skins can be compounded by materials that will be reactive at temperatures produced by infrared radiation.
