Method of heating golf ball components by radio frequency

摘要

The invention is directed to a method of heating a golf ball component by using radio frequency waves to reduce the thermal expansion experienced by a golf ball component such as a core, core and at least one core layer or a core and a combination of core and/or intermediate layers. The component is heated prior to having a layer applied in order to reduce the dramatic temperature increase the component experiences upon an intermediate layer being applied. The preheating reduces the amount of thermal expansion the component undergoes in the casting process.
