TWI, located in Cambridge, Cambridgeshire, UK, reports it is investing in the development new facilities for Powder Metallurgy Hot Isostatic Pressing (PM HIP), and recently procured state-of-the-art equipment for powder outgassing operations.
Powder outgassing is a critical step in the PM HIP manufacturing process, explains TWI. It reduces various gaseous species and moisture content in the powder-filled canisters prior to HIP consolidation.

TWI acquired a modernised outgassing system equipped with a residual gas analyser (RGA). This unique combination enables the outgassing of powder-filled canisters to achieve very low vacuum levels while monitoring both the vacuum levels and the reduction of gaseous species and trapped moisture inside the powder filled canisters.
The addition of this system will allow TWI to produce safety-critical industrial parts, replacing the conventional manufacturing routes of casting, forging, welding, and machining.
