A delivery system for dispersing either hot air or water uniformly to the outer surface of a shell mold used for forming a thin molded shell, for the respective fusion and cooling phases thereof. The delivery system includes a plurality of distributors, each having a central water inlet surrounded by an axially adjustable outer shell, with the latter having a frusto-conically shaped upper end which cooperates with the upper edge of the central water inlet to selectively close off or vary the annular opening therebetween for controlling the flow of air at a predetermined temperature form the space intermediate the central water inlet and the surrounding outer shell.
