Hot Isostatic Pressing


Hot Isostatic Pressing (HIP) is a proven technology for heat treatment consolidation of powder and removal of porosity from castings. Common applications for hot isostatic pressing include defect healing of castings, consolidation of powder metal and ceramic parts or diffusion bonding. HIP can achieve 100% of maximum theoretical density, as well as improve the fatigue properties of critical, high-performance parts, such as aerospace components.
Stack’s unique HIP capabilities include combining HIP and Heat Treatment of special alloys, which avoids re-heating of the material. This enables tailored heat treatment cycles under pressure for superior quality and optimal material properties. With Stack offering the distinct combination of HIP and heat treating, we will continue our mission of providing our clients with industry-leading quality, delivery, and engineering services.
