3600 SERIES Hot Press Sintering Furnaces

3600 SERIES Hot Press

Centorr/Vacuum Industries’ Hot Press Sintering Furnaces are part of a long standing tradition of quality, dependability, and innovation in high temperature vacuum and controlled atmosphere heating technology.

The hot press furnaces’ hot zone is resistance heated (induction systems available), and is thermally insulated from the cold-walled vessel by a multi-layer configuration of metallic radiation shields, or rigidized fibrous graphite insulation. Access to the hot zone for loading/unloading, as well as for routine maintenance and inspection is through the full opening front door. Clamps are provided for operation at slightly positive pressures (up to 2 psig).
