概要

Hot Isostatic Pressing (HIP) is a manufacturing process used to reduce the porosity of metals and improve their mechanical properties and workability. This process involves applying high temperature and high pressure uniformly around the metal, typically using an inert gas such as argon. HIP is widely used in various industries, including aerospace, automotive, medical, and energy, due to its ability to produce components with enhanced strength, density, and fatigue resistance.
