Abstract
A one-piece cast metal heat-exchanging forming tool is prepared using an expendable porous preform that is cast in place within a cast metal forming tool. The expendable preform is thereafter extracted to leave behind a network of inter-connected pores and passages within the body of the tool through which a heat transferring fluid may be circulated to transfer heat to or from a substantially non-porous contoured shaping surface of the tool. Fluid distribution/collection lines and vacuum lines may be incorporated in the tool during casting.
