Powder metallurgy describes a Innovative manufacturing processwhere Metal powder is transformed into solid and extremely robust components by pressing and subsequent sintering. This technology opens up new possibilities for the industry, as it allows, Components with complex geometries and exact specifications that are difficult or impossible to realise using conventional methods.
The use of metals in powder form is by no means coincidental, but has clear advantages:
- Significant cost savings compared to alternative manufacturing processes, for example through reduced material loss and simplified process steps.
- Specific material propertiesthat cannot be achieved with conventional manufacturing processes. These special properties include controlled porosity, optimised mechanical properties, precise magnetic and electrical properties and special high-temperature resistance.
Metal powders are produced using various processes, including Mechanical shredding, Electrolytic deposition, chemical reduction or Atomisation of liquid metal.
The properties of the powders, in particular Grain size, Grain size distribution, Shape, Surface finish and inner structurehave a significant influence on further processing and the quality of the final components.
Powder metallurgy has become an indispensable technology in numerous industries. Its strength lies in particular in the Efficiency, Precision and Sustainabilityas there is virtually no material waste and resources can be optimally utilised.
