A mold assembly designed for casting a layer for a golf ball is disclosed herein. The mold assembly has two halves that each hold a plurality of mold inserts. Each mold half is composed of a carrier base, a carrier plate, a retainer plate and a plurality of mold inserts. The multiple component aspect of each mold half allows for a more efficient transfer of heat during a casting process. Preferably, the mold assembly is utilized to mold a polyurethane cover on a golf ball precursor product.
