Powder metallurgy and additive manufacturing are reshaping aerospace production, and Hot Isostatic Pressing (HIP) is the finishing touch that ensures material integrity. By applying high heat and pressure, HIP transforms powder-based parts into fully dense, high-strength components ready for the extreme demands of aerospace service.

According to Stratview Research, the aerospace hot isostatic pressing market is likely to rebound at a promising CAGR of 4.9% in the long run to reach US$ 217.3 Million in 2032.
