One of the mold assemblies comprises a fixed mold core, and a movable mold core movable with respect to the fixed mold core along a core axis between a closed position and an open position. The mold cores include casting surfaces disposed such that in the closed position the casting surfaces cooperate to define a second mold cavity therebetween extending transversely to the core axis and in communication with the first mold cavity for casting a remaining portion of the object integral with the first portion, while in the released position the object is substantially released from the one mold assembly.
