Isostatic pressing is a versatile manufacturing process used across multiple industries to enhance material properties and produce high-performance components. It involves applying uniform pressure from all directions to materials, which reduces porosity, increases density, and improves mechanical properties. This process is widely used for powder consolidation, defect healing in castings, and creating advanced materials for industries such as aerospace, automotive, medical, energy, and electronics. It is particularly valuable for producing complex shapes, high-strength ceramics, and alloys that are difficult to manufacture using traditional methods. Additionally, it plays a critical role in energy storage technologies like lithium-ion batteries and fuel cells, as well as in the production of pharmaceuticals, explosives, and nuclear fuel.
