Hot Isostatic Pressing (HIP) is a process of fabrication, wherein the materials being processed will undergo high temperature and isostatic gas pressure (often inert gas—e.g. argon) that is applied to the material in order to densify a component, and increase density and improve ultimate mechanical property. Typically, HIP is used with metals, ceramics, and composites.

 
Key features-:

• Isostatic Gas Pressure Packing: The material will be under the influence of high-pressure gas uniformly, in all directions (isostatic) resulting in consistent deformation and compaction.
• Improved Material Properties: HIP enhances strength, ductility, and fatigue properties because the process eliminates voids, and closes internal pores present in the body.
• Excellent for Complicating Components: Mostly used in aerospace, medical, and additive manufacturing industries, to ensure parts are constructed to a high precision with a high Structural Integrity.

Hot Isostatic Pressing is a very common process used to improve the quality of castings, sintered parts, and 3D-printed parts. As an example, when dealing with complex and highly-specified components in the aerospace industry, turbine blades/structural parts may need to go through HIP, which will assist with displacing air, and also help ensure the part will properly sustain the extreme temperature and stress. In a medical implant, HIP can be used to verify biocompatibility and strength.
