HIPping to improve resilience and workability
The HIP process is a heat treatment that involves the use of an inert gas (usually Argon) at a high temperature and high pressure with the aim of eliminating the microporosities / micro-fractures inherent in the material or consolidating the metal powder inside special capsules for the creation of solid pieces completely dense and with almost definitive geometries.
The HIP treatment significantly improves the mechanical properties of the treated parts increasing their resilience and workability. The hot isostatic pressing process is already widely applied in the biomedical world and is also spreading to the aeronautical and energy world to improve components performances.
The continuous resort to additive manufacturing in different sectors requires an increasing use of the hipping treatment to eliminate microporosities and densify the material: thanks to the addition of this new service, TAG customers can take advantage of a complete, verticalized and strategic offer in the field of heat treatments.
Hot Isostatic Pressing
If you don’t know how to explain it in a simple way, you haven’t understood it well enough “(Albert Einstein)
Hipping treatment in TAG.
The Hot Isostatic Pressing process that TAG offers to its customers is optimal for eliminating micro-porosities / micro-cracks inside the materials and enhancing their characteristics.
In Cremella, TAG has two systems dedicated to the HIP treatment: the first, dedicated to parts production, is equipped with a cylindrical molybdenum thermal chamber (1000 mm in diameter by 1500 mm in height) capable to reach the maximum operating temperature of 1400 ° C and a maximum pressure of 175 MPa; the maximum capacity of the system is 10 Ton.The second one, dedicated to R&D activities, has a thermal chamber made of graphite (77 mm in diameter by 150 mm in height) and it’s capable to reach 2000 ° C of temperature and 200 Mpa of pressure; maximum load of 10 Kg. Both systems use Argon as process gas.
