Isostatic Presses

Isostatic Presses – Hot, Cold, and Warm

Isostatic Presses use a pressure vessel chamber to compact a powder or material placed in a sealed tooling, bag, or other container. Cold isostatic presses (CIP) use an oil-water mixture pressurized up to 100,000 psi (7,000 bar). Hot Isostatic Presses (HIP) use an argon atmosphere or other gas mixtures heated up to 2100º C (3800º F) and pressurized up to 60,000 psi. Warm Isostatic Presses (WIP) use an oil-water mixture that is heated up to 650º C (1200º F) and pressurized up to 100,000 psi.

EPSI has manufactured isostatic presses in hundreds of numerous configured diameters, void lengths, and operating pressures. We have supplied CIP, HIP, and WIP specialty vessels as long as 14.3 meters (47 feet) long and vessel diameters as large as 1930 mm (76 inches).

Isostatic Presses

Medium Size & Pilot Production Cold Isostatic Presses (CIP)

  • Typical pressure vessel inside diameter up to 300 mm (12 inches)
  • Compact free standing on the floor units or modular units when vessel needs to be standing in a pit
  • Top closure handling devices with or without load handling system
  • Customized units with numerous options for controls, automation, fluid filtering, decompression, etc.

Warm Isostatic Presses (WIP)

  • Similar to Wet Bag CIP processing
  • With further provision to heat the load and pressurizing fluid, normally used for products requiring a chemical reaction during the phase of compaction
  • Temperatures typical between 100°C (212°F) and 300°C (572°F)

Laboratory Units (HIP)

  • From hot zone diameter 70 mm (2.75 inches) upwards
  • One or two zone furnace design
  • Advanced computerized controls
  • Interchangeable furnaces for various temperatures and atmospheres
  • Flexible computerized programming of cycles, data-logging, etc.
