Mold assemblies and methods for compression molding dual cores of golf balls are provided. The mold assemblies and methods for molding dual cores allow for direct and independent temperature control of both the shell forming plate and the mold cavity plate during manufacturing of the dual cores. The shell forming plate and the mold cavity plate are temperature-controlled by independent platens. The ability to precisely control the temperature of the shell forming plate independent from the temperature of the mold cavity plate prevents under and overcuring of the outer core layer, which can adversely affect core durability, concentricity, and manufacturing yields.

A unique method of embedding an RFID chip into the core of a golf ball and using it in the application of a limited flight range ball for use in a range setup that can receive and monitor RFID signals is disclosed herein. The density of the core material is adjusted in relation to the mass of the RFID chip. The golf ball with an embedded RFID chip conforms to a mass limitation of the USGA.
