Customized Vacuum Hot Pressing Furnace up to 2000oC & 2" Pellets - OTF1700X-HP

Vacuum Chamber 

• The vacuum chamber is made of stainless steel with a water cooling jacket.
• Inner chamber size:  500 mm Dia. x 700 mm Height
• Hinged type of front door with a glass window.
• Vacuum level:  10 -5 torr via turbopump or diffusion pump

Heating Furnace

• The heating furnace is built inside the vacuum oven with the thermal insulation layer made of fibrous alumina.
• The dimension of the heating chamber is dependent on the pressing die's size. 
• The heating element is dependent on Max. working temperature and optional as the below
•  500ºC- 1200  ºC       heated by NiCrAl coil  via K type T/C  ( the lowest cost )
• 1200ºC - 1700ºC  heated by MoSi2 rods via B type T/C ( the higher cost )
• 1200ºC - 2000ºC  heated by Induction coil via B or C type T/C with heating rate 10ºC/S
• Please let us know your working temperature range when you ask a quotation

Pressure loading

• Electric mechanic pressing machine is built inside the vacuum chamber up to 10 metric tone
• Max. 10 T load will apply to the pressing die and produce 50 MPa pressure for 2" dia. ID die
• Digital pressure control for constant pressure within +/- 1 kg
• An electric hydraulic pressure machine is available upon request.

Pressing Die
  

• The standard die is made of high purity graphite via HIP
• Graphite die is used under vacuum and inert gas atmosphere only
• Max. die  size is 180 mm OD x  180 mm Height
• Max. the pressure of graphite die is 50 MPa    ( for example 2"ID die at max. 10 T load
• For use under air or oxygen atmosphere,  you shall use Alumina die, which is available upon request.

Temp. Controller 

• Precision digital temperature controller with automatic PID tuning.
• Temperature profile that contains a maximum of 30 programmable segments to control heating, dwelling, and cooling
• Temperature accuracy: ± 1ºC

Control Panel 

• Requires at least 55 liters per minute water flow. Please click on Pic. 1 below to order at an extra cost
• Vacuum level: up to 10-5 Torr by our turbopump station (EQ-PAC-LD) turbo pumping system pump) or 7.5 mTorr by a mechanical pump. the pump is available upon request (Pic. 2, 3)
