A cooling circuit for a neck ring of a preform is conformed to the surface of the neck ring by providing a neck ring in two parts. The first part supports the neck ring and provides strength and durability to the neck ring insert. The second part is formed of porous steel impregnated with highly thermally conductive metal and includes a cooling channel that provides substantially uniform cooling around the neck ring of the preform.
