Hot Isostatic Pressing

The Hot Isostatic Pressing process models densification of parts through the simultaneous use of both high temperature and high pressure. The pressure is applied equally to all surfaces of the part by an inert gas, which the cost model assumes to be Argon.

Each machine cycle has the following phases:

• Purge phase: air inside the vessel is replaced with the process gas.

• Pressurize phase: the vessel is pressurized to the hold pressure.

• Heating phase: temperature inside the temperature-controlled hot zone, within the vessel, is ramped up to the hold temperature.

• Hold phase: parts are held at high pressure and temperature within the hot zone for a period of time.

• Cool phase: the hot zone is cooled to ambient temperature.
