2000℃ Hot isostatic pressing (HIP) Furnace

The working principle of the hot isostatic press is a process in which the temperature and pressure are uniformly applied to the treated parts in the sealed ultra-high pressure vessel according to Pascal principle, so that their performance is obviously better than that of other methods. The pressure medium is usually argon and nitrogen. Reasonable temperature and pressure can better control the growth of grains and the identity of structure and performance, so that the performance of parts treated by hot static press is superior.

Application

In the spacecraft manufacturing industry, hot isostatic pressing is mainly used to manufacture dense carbon structural parts, such as the rudder of rocket and the nozzle throat lining of solid rocket motor.

Precision castings of various alloys, such as superalloy turbine blades, cast titanium gearbox and aluminum alloy castings of turbocharger, can eliminate internal porosity and shrinkage after hot isostatic pressing densification, and improve performance, reliability and service life. Hot isostatic pressing is also an effective method to repair core parts to prolong service life.
