Abstract
A method for compression molding a thin cover layer over a large or soft core golf ball, wherein the process includes mold press speed of closure, pressure within the mold cavities, temperature of materials being molded, and the movement of the compression press is controlled by as the mold position rather than any fixed amounts of time. A Ram press is moved in a very controlled fashion during the low pressure stage by a servo controller, and is governed by data fed to a control computer by a linear potentiometer, which allows for a very deliberate movement, especially over the last 0.4 inches of closing. A pressure transducer and thermocouples determine the flow point of the cover layer. Once the cover material starts to flow, the Ram press is triggered into a high pressure close wherein the cover layer is formed and then finally cooled.
