Powder metallurgy deals with the production of metal powders and their further processing. With the combination of PM and HIP, a powder is filled into a welded capsule. The capsule is welded as close to the final shape as possible to enable optimal use of the raw material "powder" and to work resource-efficiently. After filling, the capsule is closed under vacuum and recompacted by the HIP - Hot Isostatic Pressing process into a component that is used for further processing of the finished part. When components are HIP treated, the simultaneous application of heat and pressure eliminates internal voids and micro-porosities through a combination of plastic deformation, flow and diffusion bonding of the material. The powder is thus compacted into a solid.
Advantages of the process for your products
The PM | HIP offers you the following advantages:
- Optimum use of the raw material due to the near net shape blank after the HIP process
- No round steel needs to be laboriously processed
- Mechanical processing is reduced to a minimum
- High availability of different powders with better properties
- Blanks can be produced from a material that is only available in powder form
- Significantly reduced use of raw material
What powder materials are available?
- Stainless steels
- Tool steels
- High-speed steels
- Ni-based alloys
- Co-based alloys
Other powders can also be produced on request. We maintain a close partnership with various powder manufacturers who, in addition to large quantities, can also supply small quantities for prototypes and special alloys.
