Vacuum Rapid Heated Pressing Furnace up to 1600C & 50 Mpa with 0.5" Graphite Die - OTF-1700X-RHP4
   

      Product Introduction
  • OTF-1700X-RHP4 is a Vacuum Rapid Heated Pressing Furnace (VRHP or RHP) designed for making dense pallets under vacuum or the protective gas environment. A 15 kW temperature controllable induction heater is integrated into the system, which provides sufficient power for rapidly heating the graphite pressing die up to
    1700 °C . The Induction coil is built inside of stainless steel vacuum chamber. An electric hydraulic press is inserted from the bottom of the chamber, providing up to 5 tons pressing force.
      Specifications :

      Max. Pressure
  • 5 metric tons (10 MPa on pressure gauge).
      Hydraulic Electrical Presser

      

  • Piston diameter: 60 mm.
  • Vertical move distance: 35 mm.
  • Automatic pressure controller

      

  • Working voltage: 208 - 240 VAC, 50/60 Hz, three phase (380V three phase available upon request)
  • Working current: 40 A (with a 60 A breaker).
  • Maximum input power: 15 kW.
  • Output frequency: 30 ~ 80 kHz.
  • Duty cycle: 80%
  • Max. Working Temperature : 1600 °C max duration time: < 30 min.
  • Ultimate Temperature: 1700 °C <1 min. (This might cause damage of thermocouple)
  • Air cooling: fan.
  • Protection: water pressure monitoring, high-temperature protection, and overpower protection.
      Processing chamber & Sealing Flange

      

  • Stainless steel vacuum sealed chamber: 260 × 230 × 320 mm (OD × ID × L).
  • Flanges on both ends of the chamber. Flanges have a tunnel for cooling water.
  • Equipped with a KF-25D vacuum port, pressure gauge, 1/4" gas inlet port with the stainless steel needle valve.
  • The upper flange can be lifted by raising the lead screw which provides the easy access to retrieve the graphite die.
  • Requires at least 55 liters per minute water flow. Please click on the picture below to order at an extra cost.

      High-Temperature Graphite Pressing Die Set
      

  • Two built-in graphite supporting rods with Max pressure 50 Mpa
  • One set of 0.5" (inner diameter) graphite die are included for immediate use.
  • Made of high purity graphite by HIP processing, Max. Load from the hydraulic press is dependent on die 's ID
    • 0.5"ID Max. 0.5T ( sample pressure 50 Mpa )
    • 1.0 ID: Max. 3T ( sample pressure 50 Mpa, which is optional)
  • Mica spacers are used to adjust the height of die sets and insulate heat.
   

  • Note: The maximum pressure range of graphite dies will vary depending on the inner diameter of the die. For example, the graphite dies with an inner diameter of 0.5" can withstand 0.6 metric tons. For the graphite die with an inner diameter of 1" can withstand 3 metric tons.
      Dimensions


  • 800 × 800 × 1300 mm (L × W × H).
      Net Weight
  • 350 kg
       Application Notes
  • Attention: the gas cylinder must have a two-stage pressure regulator to limit the pressure below 3 psi for safe operation.
