The raw material is melted via induction: molten metal droplets continuously flow out and are poured onto the surface of a vibrating element.
Mainly used for low melting point materials (1200-1300°C)
The plate on the vibrating surface is made of refractory metal.
From tin alloys, magnesium alloys, aluminum alloys to copper alloys, atomized powder production has not resulted in any impurity contamination.
After multiple experiments, no impurities related to the material of the ultrasonic device body were found, so it was determined that the solution from induction melting could be directly poured onto the surface of the vibrating element.
Plasma Arc Melting: The material is melted directly on the ultrasonic generator.
It can be non-melting (continuously cooled)—in this case, only the material placed on top is atomized, or a consumable sonotrode can be used. For example, for steel with nearly pure iron or similar chemical composition, a sonotrode can serve as an ultrasonic generator without introducing any impurities. In this scenario, the processed material is "welded" to the top of the ultrasonic generator and then atomized.
