Vacuum Hot Press Structure
  • Two flat heating platens made of high-temperature alloy with max. the working temperature of 500ºC
  • The Heating element is inserted into the center of the heating plates for fast heating
  • Two precision temperature controllers which control two heating plates separately with 30 programmable segments 
  • Water cooling jackets are built on both the top & bottom of the heating plates for assisting cooling. Cooling water inlet and outlet are for 12mm O.D polyurethane tube. 

  Hydraulic Pump

  • The modified electric hydraulic press is installed under the table and connected to a vacuum chamber.
  • Max. the travel distance of the bottom ram: 15 mm
  • Automatic max. pressure controlled via a digital pressure gauge
  • Pressure accuracy: +/-0.01 Mpa ( 0.1 kg/cm²)
  • Water cooling  (>16L/min) is required to cool the heating plates when the temperature is over 200 ºC.

Temperature control and Pressure Display

  • Two precision temperature controllers with 30 programmable segments control the heating plates separately with +/1°C accuracy. 
  • The temperature controllers have PID auto-tune function, over-temperature protection, and thermal couple broken protection
  • Max. Temperature: 500°C with inert gas or vacuum with accuracy +/-1°C
  • Max. Heating rate:  5°C/min
  • A digital pressure meter ( controller ) is built in the control panel. You can set pressure at the desired value which can stop the electric hydraulic press automatically

Vacuum Chamber

  • Electric hydraulic press and heating plates are placed inside the vacuum chamber
  • The vacuum chamber is made of SS304
  • 300mm dia. vacuum-sealed hinged type door with 150mm Dia. the quartz glass window is installed for easy sample loading and observation
  • Silicone O-ring can be used for all vacuum sealings 
  • One precision digital vacuum gauge ( 10E-4 torr ) is installed on the vacuum chamber

Optional equipment is available at extra cost:
  • One recirculating water chiller for the cooling-heating plate from over-heated and faster cooling is required. please picture left to order.
  • Vacuum level for the mechanical pump can reach 300mTorr, and can reach 10E-4 torr with quality turbopump (Pleases click the picture left to choose one)
