Powder metallurgy is a cutting-edge technology for material process by mixing, compacting and sintering metal or non-metal powder. |
|
|
 |
Economical
- Mass production is possible by automated high-speed compression molding.
- Very economical by alloying through sintering at temperature below metal’s melting point.
- The measurement is consistent by production through metallic mold.(±0.02mm)
- Almost no post-processing required, no waste of materials from cutting.
Original
- By randomly mixing various types of metals, density, hardness and strength are adjustable.
- Porosity is adjustable by adjusting power grain size, shape, welding force and sintering temperature.
