Metal powder atomizer TMA-W series

TMA-W is a family of water atomizers designed to produce metal powders of irregular shape for use in industrial, chemical, soldering paste, resin filter, MIM and sintering applications. The atomizer is based on an induction furnace working in a closed chamber under protective atmosphere, where the molten metal is poured and hit by a high pressure water jet, producing fine and deoxidized powders. The induction heating ensures a very good homogenization of the melt thanks to the action of magnetic stirring during the molten phase. The die unit is equipped with an auxiliary induction generator that allows the cycle to be restarted in the event of an interruption. After the melting and homogenization steps, the metal is poured vertically through an injection system located at the bottom of the crucible (nozzle). Multiple high-pressure water jets are directed and focused onto the metal stream to ensure rapid solidification of the alloy into a fine powder. Real-time process variables such as temperature, gas pressure, induction power, oxygen ppm in the chamber and many others are displayed in both numerical and graphical formats on a monitoring system for intuitive understanding of the work cycle. The system can be operated manually or in fully automatic mode thanks to the programmability of the entire set of process parameters through a user-friendly touch screen interface. The monitoring system can be easily connected to the factory network via Ethernet.
