Continuous Vacuum Furnaces

The C.I. Hayes “CV” Continuous Vacuum Series belongs to a family of vacuum furnaces comprised of modules including loading, heating and quenching.  The modular and, in this case, continuous premise is to index small lots in a continuous automatic fashion that combines high production with superior product quality.  Processing of small lots allows for tighter temperature uniformity within the work area, as well as similar thermal profiles within the work lot – center to edge.  To further increase part quality, the heat chamber module of the “CV” is not thermally cycled.  It remains at temperature and under vacuum during production, not exposed to room air except for routine maintenance needs.  The modular heat chamber is consequently an extremely pure environment that contributes to the part quality.


Designs of the modular “CV” vacuum furnace can produce up to 1500 lbs/hr (680 kg/hr) reaching temperatures up to 2600°F (1427°C).  The “CV” furnace is capable of many processes, including annealing, brazing, hardening, carburizing and sintering.
