ATO Noble Precious Metals Powder Atomizer


Built on the ATO Lab plus platform, the ATO Noble is a unique and small machine used specifically for economic atomization of expensive, precious metal alloys.

ATO Noble utilizes a precisely calibrated ultrasonic system which allows the system to process materials such as gold, silver, platinum, etc. with minimum loss of the materials. The use of a dedicated filtration system allows the user to minimize material losses of precious alloys below 1% and facilitate their subsequent recovery for reuse.

The application areas of ATO Noble are jewellery, healthcare, electronic industry, aerospace and metal processing industry
