Integrated Solutions for Production and Conditioning of High-Quality Alloyed Metal Powders

In metal additive manufacturing and HIP-related processing, powder quality is not an auxiliary issue – it is one of the foundations of the final part quality. Particle shape, cleanliness, internal porosity, moisture content, gas contamination and fraction consistency influence powder handling behavior, feeding stability and the repeatability of subsequent thermal and consolidation operations.

A well-designed production line therefore has to control not only the initial generation of granules powder particles, but also the downstream conditioning steps that determine how the metal powder will behave during 3D printing, HIP densification and post-processing. The quality of the starting material contributes directly to structure formation in the metal and, as a result, to the reliability of the finished component.

This process equipment family covers the production and conditioning of high-quality metal powders for powder-based 3D printing and hot isostatic pressing (HIP). The line combines primary powder production with downstream classification and magnetic separation, cleaning from non-metallic inclusions, all operations done in vacuum cleaned all-inert conditions, hot vacuum degassing required to deliver a stable, application-ready metal powder. For HIP the powder can be delivered in sealed containers or filled into HIP capsules with all preparation steps ready for HIP.

The technological chain begins with the Plasma Rotating Electrode Process (PREP), used for the production of spherical metal powders without entrapped gas porosity, with narrow PSD, excellent flowability, low O2 content and a morphology suitable for demanding downstream applications. This is followed by fraction classification combined with magnetic separation for controlled particle size distribution and removal of metallic contaminants, electrostatic separation for the dry removal of non-metallic inclusions, and thermal-vacuum degassing to remove residual gases from the powder surface.

For HIP applications the process can be extended to a dedicated module for thermal-vacuum degassing, controlled HIP capsule filling to a required tap density and reliable hermetic sealing, all done in vacuum.

Each stage may be supplied either as a standalone installation or as part of an integrated full-cycle production line. This modular architecture allows the solution to be adapted to different production scales, alloy systems and plant layouts, while maintaining a single process logic across the entire chain.
