Abstract

See full text

A compound sintering furnace with managed contamination for debinding and sintering parts. An inner insulation layer is disposed within an outer insulation layer and has an internal hot face surrounding a work zone. A sealed housing surrounds the inner insulation layer and is composed of a refractory material capable of withstanding a service temperature greater than a debinding temperature and less than a sintering temperature. An outer heater system is configured to heat at least a portion of the sealed housing and externally heat the inner insulation layer to, in conjunction with an inner heater system, heat the work zone to the debinding temperature, and inhibit condensation of a binder within and upon the inner insulation layer during a debinding process. The inner heater system is configured to internally heat the inner insulation and heat the work zone to the sintering temperature.
