A hot isostatic press uses inert gases as the main pressurizing medium. This is because it is necessary to heat up the object to the maximum operating temperature of 2000℃, which is well beyond the evaporation temperature of the fluid. Even though this is a lower pressure level than those of cold or warm isostatic presses, the pores in the object are eliminated and the object can be processed closest to the theoretical compressible density of the target object. For this reason, this system is also called the ultimate extreme processing equipment. The gas porosity and defects that are commonly discovered in a casting process are eliminated, and hot tearing susceptibility is reduced while the fatigue behavior is improved. With a HIP process, the creep life span of the object is enhanced, while it becomes more resilient in the face of fatigue, with a higher level of toughness. In addition, the HIP is now expanding its scope of applications, from the traditional metallurgical applications to diffusion bonding, which serves as a follow-up process for 3D printing to complement its poor density; making it a viable option for meeting the demanding quality requirements of today.

High-tensile-strength steel is tube-forged to make it safer. As welding is never done in any part, there is no concentration of stress.
Also, the inside and outside surfaces are hard-chrome-coated, to increase resistance against corrosion and make the surface tougher.
The cooling jacket is composed of stainless cylinders joined together with bolts, so that it can be disassembled.

The joining grooves in the joining mechanism further enhance safety, and the weight is reduced significantly to make it easier to handle and maintain.
The doors also do not include any welded parts and allow disassembly or cooling jackets.

The heater is easy to assemble/disassemble. Another heater is located at the bottom to further reduce temperature differences.

A thermocouple and a pyrometer (in the case of a high-pressure application) are used. Especially we used a single-crystal rod to reduce the discrepancies in a pyrometer due to the turbulence of high-pressure gas.
