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 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).
The inside of the furnace chamber conforms to the best vacuum and controlled atmosphere practices, with particular attention given to the surface finish and choice of materials. The design and construction of high-quality furnaces calls for minimizing component surface area and potential leaks; thus you won't find inferior metals or ceramic refractory insulation in a Centorr/Vacuum Industries Hot Press furnace.
Visual observation of the process material is provided by a sight port equipped with the Centorr-designed rotatable quartz viewing glass. Ports are provided for gas inlet(s), thermocouples, gauges, and other pertinent instrumentation. All instrumentation is positioned in an attractive console for optimal monitoring and control. Furnace temperature is controlled by a closed-loop circuit between the temperature sensor (thermocouple, power transducer, or optical pyrometer), the control instrument, and the power supply. The entire furnace system is protected by a water-flow interlock that shuts down the hot zone if cooling water flow is reduced or closed off. Additional protection is provided by gas pressure or flow sensors which monitor the incoming process gases; unacceptable conditions trigger a visual and audible alarm.
These furnace systems are ready to operate as soon as connections are made to the proper utilities. Each Centorr/Vacuum Industries' Hot Press Sintering furnace is completely assembled and thoroughly tested before it is shipped.
