Double Door Tungsten And Carbide Sintering Furnace With ±5 ℃
Temperature Uniformity
Sintering Furnace Applications
Common applications are the sintering of metal or ceramic powders,
carbon/graphite/CFC processing, the manufacturing of hard metals
such as Tungsten and Carbide, and most non-oxide advanced ceramics
including BN, AlN, SiC (pressureless sintering, reaction-bonded,
and recrystallized), Si3N4, B4C, AlON, and others.
These materials can be processed in any combination of furnace
atmospheres including high-vacuum, rough vacuum, partial pressure,
or positive pressures of inert or Hydrogen gases.
Sintering Furnaces are Used in a Variety Of Industries
- Cutting Tool Manufacturers
- Powdered Metal Parts Users
- Advanced Ceramics Companies
- Body and Vehicle Armor Producers
- Aerospace Companies
Technical parameters
Valid working space | Customizable |
Max design pressure | 10-100bar |
Pressure time | Less than 25 min to reach 58 bar. |
Cooling time (full load) | Cooling time for sintering Temperature 1450℃～100℃: 7-8h (WaterTemperature≤30℃, 55bar≤pressure≤58bar) |
| Max.loading weight | The load capacity depends on the product type) |
| Power rating | About 400KVA (The output power can be limited) |

Max. Design Temperature | 1600℃(while vacuum sintering) |
Max. Working Temperature | 1550℃(vacuum and pressuring) |
| Pumping speed | The vacuum degree can reach 5Pa within 30min after starting the
pump. After reaching 5Pa and then pumping for 60min, the ultimate
vacuum value reaches 1Pa (within a cold, empty and clean furnace
that has been dried before). |
| Leakage rate | ≤3Pa/h (stop the pump group operation and start checking after
testing the limit vacuum (within a cold, empty and clean furnace
that has been dried before). |
| Wax yield rate | ≥98%(10Kg pure paraffin, argon negative pressure dewaxing. Measured
by three times of mean values at most). |
UPS guarantee time | It can power the indicator light and control the furnace during
power outage for more than 80 minutes. |
| Max.heating rate | 8℃/min (the room temperature rises to 1900℃within a vacuum and
empty furnace. 600℃, 1000℃, 1200℃ half-way insulation is allowed). |
