hot isostatic pressing (HIP)

HIP means hot isostratic pressing, a process which is used for quality improvement of powder metallic products or founding parts. In the process the parts are redensified in special autoclaves at high temperatures and through the high, all side pressure of an inert gas. The pressure can be up to 200MPa and the temperature up to 1400°C. CVD-zinc sulphide can be transferred from the opaque FLIR-quality into the multispectral form by means of an HIP-Process.
