A major aerospace manufacturer has contracted with Consolidated Engineering Company (CEC) for a drop-bottom furnace to be to be installed in a foundry for aerospace castings in Iowa. The parts being treated are a critical component on the aircraft and must be treated in a precisely controlled manner. These parts are currently being processed using pit-furnace equipment.

The aerospace-castings customer reported that the key considerations, which led to the choice of the drop-bottom furnace, were heat-up, thermal uniformity and quenching.
