VIGA Process Working Principle 

The metal & metal alloy are melted under vacuum conditions with protective gas. The metal liquid flows through thermal insulating crucible and diversion tube to the atomizing chamber. Meanwhile, the liquid will be atomized & cracked into small droplets by high pressure air flow via tight coupling nozzle. The droplet will solidify into spherical or semi-spherical particles during falling down.
