Our small vacuum sintering furnace is the top loading furnace .It is a popular choice for small batch processing. This furnace has a standard hot zone of 4″ diammeter by 8″ high with many other sizes available.
This furnace has a maximum temperature of 2500°C with a tungsten hot zone, 2100°C with a tantalum hot zone, and 1650°C for molybdenum.
The hot zone provides excellent temperature uniformity and longevity. This furnace comes equipped with an intuitive HMI control package providing features such as automated runs, process overviews, data-acquisition, alarms, unlimited recipe profiles for temperature control, user security, etc. Classic push-buttons and discrete controllers are also available.
Features:
l High-Temperature Versatility: Reaches up to 2500°C with tungsten hot zones (tantalum/molybdenum/graphite options) for diverse sintering needs.
l Flexible Environments: Operates in high vacuum (10-7 Torr), positive/partial pressures (e.g., H₂, N₂, Ar) with NFPA-compliant safety for flammables.
l Advanced Controls: Intuitive HMI manages temp (auto-switching sensors), vacuum/gas systems, and data logging; optional manual controls available.
l Robust Design: Double-walled stainless steel chamber with layered heat shields, removable load assemblies, and multiple utility ports.
l Safety & Efficiency: Water cooling (≤45°C exterior), pressure relief systems, and rapid vacuum pumping minimize oxygen exposure.
l Customizable Utilities: Adaptable power (40 kVA), water, and gas inputs to fit specific operational requirements.

CHAMBER AND HOT ZONE | Hot zone materials and maximum temperatures: - Tungsten: 2500°C - Tantalum: 2100°C - Optional: Molybdenum, graphite - Hot zone structure: Top-loading cylindrical chamber, made of double-walled stainless steel; fully welded and polished for vacuum integrity and appearance - Heat shields: Layered heat shields surrounding the load and heating element to reduce power loss - Load assembly: Removable, manufactured from hot zone material (when material compatibility is required) - Ports: Multiple ports for sensors, vacuum, gas, hot zone power, and a sight window |
PROCESS GAS SYSTEM | - Operable environments: Positive pressure gas environments, partial pressures (below atmosphere) of gases (e.g., dry/wet hydrogen, dissociated ammonia, nitrogen, argon) - Maximum operating pressure: 5 PSIG - Safety components: Pressure relief valve, 30/30 compound gauge (located on top chamber) - Special features for flammable gases: Gas burn-off and explosion port (compliant with NFPA requirements) - Flow control: Optional mass flow controllers for programmable gas flows (alternative to manual controls) |
VACUUM SYSTEM | Pumping capability: Turbo high pumping system capable of reaching 10-7 Torr vacuum range - Components: - Rotary vane pump with exhaust filter (for rough vacuum and turbo pump backup) - Turbo pump (other pumps available for high vacuum) - Electro-pneumatic vacuum valves (for system operation or chamber isolation) - Relief valve (to release vacuum/pressure or leak check) - Control: PC interface screens for operation and status monitoring |
POWER SUPPLY | Control type: SCR-controlled transformer package (enables high ramp-up speeds up to 2500°C) - Transformer feature: Multiple secondary voltage tabs (prevents performance degradation due to hot zone aging) - Enclosures: Furnace controls in control enclosure; circuit breakers, contactors, instruments, and wires in power supply enclosure - Regulation: Hot zone power and temperature controlled via HMI system |
UTILITIES | Power: 40 kVA, 380-480V/3/50-60 Hz (other voltages available) - Water: 8 G.P.M. (30 lpm) @ 20°C (70°F) and 50 PSIG (3.4 bar) - Process Gas (Ar, N₂, He): 30-60 L.P.M. @ 50 PSIG (3.4 bar) - Reducing Gas (H₂, NH₃): 30-60 L.P.M. @ 50 PSIG (3.4 bar) - Compressed Air: 60-90 PSIG (4.1-6.2 bar) (filtered) |
