AUW Water Atomizers

While the gas as well as ultra-sonic atomizer solutions are designed for the production of spherical powders by avoiding any contact to fast quenching media during particle formation, water atomized powder typically have a more irregular shape which is an advantage for some applications like recycling/refining process, press & sinter process and others. However, it is also possible to produce almost spherical, fine powder by water atomization with appropriate process parameters, which makes the powder potentially suitable for AM applications. Compared to gas atomization the running costs are signficantly lower..

Other Advantages of AUW-Serie

The DDP system is ensuring a constant and controllable metal mass flow, and therewith gas-to-metal ratio, independent from the melt level in the crucible.

The user-oriented and modular structure of the systems ensures optimum accessibility for all work as well as for inspection and maintenance. This construction principle also ensures short installation and training periods.

Polished stainless steel surfaces prevent powder adhesions in spray chamber, cyclone and collector – all parts are easy to clean without any residues.

Reliable production of metal powder with narrow particle size distribution and high process yield Ideal for small to medium amounts

The AU machines offer the possibility of oxidation-free processing in the closed-chamber machine by means of de-gassing, vacuum and protective gas features.

by use of different atomisation nozzles and optional use of hot spray gas Modular availability of free fall as well as close coupled atomisation nozzles to obtain specific metal powder characteristics. Fast and easy nozzle change.
