The cooling chamber has at least one mold wall with a first surface on one side of the wall and a second surface on the opposite side of the wall from the first surface. The wall has a substantially uniform wall thickness. A central plug is located inside the cooling chamber and is spaced apart from the second side of the wall. A channel is located between the wall and the central plug. The channel extends sustantially from one end to the other end of the cooling chamber. Inlet and outlet conduits are formed in one end of the cooling chamber for channeling fluid into and out of the cooling chamber.
