Vacuum Hot Press Furnace

This vacuum hot press furnace mainly used for the high temperature sintering and hot press treatment, such as inorganic material, hard alloy, function ceramic, metallurgy powder. The material density could be increased under vacuum conditions or a protective atmosphere.

Vacuum Hot Press Furnace Features:

  • The heating element could be selected according to the difference in hot press temperature and vacuum level.
  • 2 different type Vacuum Hot Press Furnace:
    – The resistance module is suitable below 1200℃
    – The graphite heater is suitable over 1200℃. (2200℃ Max)
  • The press range is adjustable below 5 tons so that it is can be used for sample sintering and hot press testing to avoid resource waste.
  • Ranging by a grating ruler with high accuracy to 0.02mm.
  • All the action of vacuum hot press furnace could be controlled by a PLC system, including temperature control, press adjustment, temperature auto tracking. All the vacuum press furnace running monitoring and data could be displayed and record on the touch screen, such as temperature, vacuum level, displacement. The data curve could check in real time.
  • W-Re thermocouple at low temperature and infrared thermocouple for high temperature. The W-Re thermocouple will be auto quit at high temperatures.
