About Hot Isostatic Pressing (HIP)


What is Hot Isostatic Pressing?

Hot Isostatic Pressing (HIP), the simultaneous application of heat and high pressure, has become a standard production process in many industries. In the HIP unit a high temperature furnace is enclosed in a pressure vessel. Work pieces are heated and an inert gas, generally argon, applies uniform pressure. The temperature, pressure and process time are all controlled to achieve the optimum material properties.

The Economics of HIPping

  • HIP processing incorporated as an integral part of the manufacturing process reduces scrap and improves yield
  • HIP frequently allows replacement of wrought components by castings
  • HIP can reduce quality assurance requirements by improving material properties and reducing property scatter. Often, the savings on radiographic costs will cover the costs of HIP
  • HIP maximizes material utilization by improving material properties
  • HIP parameters can be established to minimize subsequent heat treatment requirements
