It is a vacuum heat treatment service with over 20 years of experience and know-how.
"HIP processing (Hot Isostatic Pressing)" uses argon gas and other pressure media to apply a synergistic effect of pressure over 1000 kgf/cm² and temperatures above 1000°C for pressure treatment, representing a cutting-edge technology. By utilizing high temperatures and high isotropic pressure, we achieve high value-added products. In recent years, it has also gained attention as a method for removing internal defects in metal additive manufacturing products. 【HIP Sales Items】 ■ Removal of casting defects and sintering defects ■ Capable of processing large and complex shapes ■ Sintering ■ Diffusion bonding of similar and dissimilar materials *For more details, please feel free to contact us.
