SINTERMASTER
A Vacuum Furnace With A Graphite Hot Zone
Sintermaster vacuum furnaces are designed for sintering of powdered ceramics
and metals under closely monitored conditions. Each vacuum furnace is supplied as a complete
operating system and includes: vacuum chamber, graphite heat zone, power supply,
mechanical vacuum pump, and a programmable control system.
Standard furnaces are equipped for routine operation to 2200°C.
Alternate power supplies can be specified for lower temperature processing of powdered
metals or higher temperature processing of more refractory ceramics. Additional options
include larger vacuum pumps, cooling fans, retorts, condensers, traps, data recording, and
specialized atmospheric controls.

HIGH THROUGHPUT
Efficient thermal insulation results in low power losses, leaving ample
power reserves for fast heat-up. Larger optional power supplies can be provided for even
faster heating, as well as cooling fans for forced gas circulation and rapid cool-down.
MINIMAL MAINTENANCE
Rugged graphite resistance heating elements and fibrous graphite
insulation assure reliable operation with minimal downtime. Heat zones, pumping systems,
and control cabinets are built for easy access and fast repairs when necessary. |

HOT ZONE
Graphite resistance heating elements are surrounded by low density
fibrous graphite insulation designed to keep power losses to a minimum. Stated work zone
sizes are for actual usable volume, with generous clearance for the elements to facilitate
loading and prevent non-uniformity from 'temperature banding' effects.
Typical furnace uniformity for side mounted heaters is ±10°C from
200°C to 2500°C in vacuum, argon or nitrogen. Optional upper and lower heaters can be
provided along with a zoned power supply for balancing of power input when ±5°C
uniformity is required.
The graphite hearth is capable of
supporting the rated load at any temperature. A full workload is often less than the
hearth rating, depending on material density and the spacing required between parts. |

COMPLETE PROCESSING
Binder removal, pre-sintering, and sintering steps can all be done in
the same furnace, eliminating the need for intermediate loading and unloading, and
material transfer operations.
