Im trying to build a cold isostatic press with a internal vessel area of 300mm3. A cold isostatic press forms green metal components using pressures greater than 90,000 psi. Using an oil or water/emulsified oil solution do they use a high pressure pump and connect it to a hydraulic intensifier? Any direction is greatly appreciated thank you.

  • $\begingroup$ Are you asking about the force on the green metal in a die or pressure in a vessel ? $\endgroup$ – blacksmith37 Jul 24 '17 at 16:08

Contact an engineering firm with experience designing and building such systems and vessels to code. Otherwise, you're just building a bomb.

  • $\begingroup$ There's really nothing else that can be done here. That's an extremely high pressure vessel and is likely governed by specific codes in your area (and for good reason). You do not want one of those blowing up. I'm also a bit confused, as this seems to be a very small vessel ($300 m^3$ is less than $7 mm \times 7 mm \times 7 mm$. $\endgroup$ – JMac Jul 24 '17 at 13:59

  • $\begingroup$ 90000 psi? steels usually have UTS at 70ksi. $\endgroup$ – RainerJ Jul 25 '17 at 0:44

    $\begingroup$ There are super alloys available that have yield above 200 ksi. Used in aerospace frequently. Very expensive though. $\endgroup$ – Daniel K Jul 25 '17 at 12:03
