The Spanish manufacturer of high-pressure technology presents its range of Hot Isostatic Presses (HIP) as the key solution to densify critical components and eliminate porosity in 3D-printed parts<\/strong><\/p>\n

Burgos, Spain, 11 November<\/strong> \u2013 Hiperbaric, the world leader in industrial high-pressure equipment, arrives at Formnext to showcase its state-of-the-art Hot Isostatic Pressing (HIP) technology<\/a>. As the global additive manufacturing (AM) ecosystem gathers for its must-attend annual event, Hiperbaric positions itself as the indispensable strategic partner for the critical step that comes next: post-processing.<\/p>\n

Hiperbaric’s presence underscores a decisive commitment to providing enabling technology that maximizes the performance of 3D-printed metal and ceramic parts. HIP technology is the key to improving the mechanical properties and structural integrity of critical components.<\/p>\n

\u201cFor an industry seeking nanometric perfection, eliminating internal porosity is not an option; it is a necessity,\u201d says Andr\u00e9s Hernando, CEO of Hiperbaric<\/strong>. \u201cHIP is the technological enabler that dramatically improves the mechanical properties and structural integrity of<\/strong> critical components, making AM viable for mass production in the most demanding sectors.\u201d<\/p>\n

The Solution to Additive Manufacturing’s “Achilles’ Heel”<\/h2>\n

Hiperbaric\u2019s technology directly addresses the primary challenge of metal AM. Processes such as Selective Laser Melting (SLM) or Electron Beam Melting (EBM) create parts layer-by-layer, a method that can inherently leave residual micro-porosity.<\/p>\n

While this may be irrelevant for a prototype, for a turbine blade, a medical implant, or a high-performance racing engine part, this porosity represents a potential failure point.<\/p>\n

HIP is the post-processing step that elevates an AM part<\/a> to the quality of a forged material. It transforms a porous or micro-cracked material into a solid, monolithic, and homogeneous structure, guaranteeing it meets the strictest mechanical specifications.<\/p>\n

\n<\/strong>How Hot Isostatic Pressing Works<\/h2>\n

Hot Isostatic Pressing is an advanced manufacturing and heat treatment process that subjects components to two simultaneous forces: high temperature and high isostatic pressure.<\/strong><\/p>\n

The component is placed inside a high-pressure vessel. This chamber is heated to temperatures that can reach 2,000\u00b0C (3,632\u00b0F)<\/strong> and is simultaneously pressurized with an inert gas (usually argon) to pressures of up to 2,000 bar (29,000 psi)<\/strong>.<\/p>\n

Hiperbaric’s innovation and experience in high-pressure processing<\/strong> have enabled the manufacture of modern HIP equipment, improving performance and reducing costs. Its wire-wound vessel technology<\/strong> not only has advantages from a safety and reliability point of view, such as increased service life or the \u201cleak-before-break\u201d design that prevents catastrophic failures, but also provides advantages from a thermodynamic point of view.<\/p>\n

Being a wire-wound vessel, the cooling channels can be placed very close to the vessel wall and therefore very close to the hot zone, allowing the vessel to act as a heat exchanger, enabling fast cooling inside the equipment<\/strong>. Through a fan and valves located in the lower part of the oven, forced convection is activated by circulating the hot gas through a heat exchanger located in the upper cap, which exits and descends in contact with the wall of the vessel (which is cooled) and re-enters the oven.<\/p>\n

The ability to Fast Cooling within HIP equipment<\/strong>, in addition to the obvious advantages in terms of increased productivity, reducing production times and energy consumption \u2013 which translates into savings \u2013 has a series of advantages from a material science perspective, improving the microstructure and physical properties<\/strong>. Thanks to fast cooling, it is also possible to carry out heat treatments within the same equipment, opening the door to combined cycles (Combined HIP \u2013 Heat Treatment, CHIP-HT).<\/strong><\/p>\n
