Amaero: PM-HIP as a supply chain solution
PM-HIP: the alternative to casting and forging that improves supply chain flexibility and sustainability Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is an advanced manufacturing process that enables the production of large, high-integrity components with consistent, forged-like properties. As traditional casting and forging supply chains face growing challenges, PM-HIP offers a reliable alternative with shorter lead times and increased design flexibility. Here, Amaero’s Eric Bono explains how the process supports resilient, domestic production of critical parts across sectors such as defence, energy, and aerospace, helping manufacturers reduce dependency on constrained supply chains while achieving demanding performance requirements.
At its core, Hot Isostatic Pressing (PM-HIP) is a highly adaptable manufacturing process used to produce large, critical components Part Design with exceptional material properSimulation & PM-HIP Can Design ties and short lead times.
