During Hot Isostatic Pressing (HIP), the material to be processed is heated up in special plants (HIP plants) under argon atmosphere, high gas pressure and under high temperatures exceeding the yield point in order to compact the component. For most materials, the process pressure is approx. 1000bar = 100MPa and temperatures are up to 1400°C. The aim of the HIP process is to remove internal cavities, e.g. residual pores in cast or sintered metal or ceramic parts, in order to obtain properties comparable to those of forged materials.

During cold isostatic pressing, any desired object (powder-filled elastic moulds) are compacted isostatically (i.e. from all sides) by means of an  effective pressure medium. Thus, the compacted material is homogeneous and has a high density.


Our HIP/CIP plant types:

  • Hot isostatic press HIP ISOSTAR
  • Cold isostatic press CIP ISOMAT
  • Cold isostatic press CIP ISOPLANT


Technical Features

Hot and cold isostatic presses are relevant not only for processes concerning iron powder metallurgy, but also for Additive Manufacturing, MIM (Metal Injection Moulding ) and processes concerning refractory metal powder.
