Melting and Spraying
The raw metal is melted in a furnace.
The molten metal flows into a small crucible, called a tundish. As the molten metal flows out via a hole in the bottom of the tundish, a jet of high-pressure gas or water is used to scatter the molten metal, so that it solidifies into particles.
Classifying and Sieving
The particle size distribution of the collected powder is adjusted for the intended application using a vibration sifter or air classifier.
The particle size adjusted powder is mixed in a blender to ensure uniformity.
All lots are inspected based on powder properties, alloy components, and other criteria.
