Continuous Vacuum

The C.I. Hayes “CVCQ-LAM” Vacuum Sintering Furnace uniquely combines atmosphere delubrication and vacuum sintering.  An in-line atmosphere delube/preheat section and integral vacuum sintering chamber allow for processing of powder metal (P/M) compacts at conventional or high temperatures.

Processing versatility includes: conventional ferrous and ferrous alloy materials, stainless steels, tool steels, sinter hard alloys and custom blends. High pressure gas quenching, oil quenching or gas cooling is available.

Our proven atmosphere add-on module can process parts under dry or saturated nitrogen/hydrogen mixtures, dissociated ammonia or exothermic gas.

C.I. Hayes’ exclusive atmosphere to vacuum transition module assures continuous high volume production with the benefits of both atmosphere and vacuum.
