7. How Ultrasonic Nozzles Work
Sono-Tek is the originator of ultrasonic spray coating technology, commercializing this science in the 1970s.
Atomization is based on high frequency sound waves, and uses no pressure.
A pair of resonating transducers are located inside the nozzle body.
High frequency electrical current causes the transducers to expand and contract.
The frequency of the signal is the frequency of the nozzle (25-180kHz).
The tip resonates in an axial motion. The amount of motion is dependent upon nozzle frequency and power level applied.
When liquid is fed through a resonating nozzle, waves form on the atomizing surface.
Droplets fall off the tips of the waves. These droplets have a mathematically definable size.

10. Drop Size
More precise, more repeatable, more uniform coatings with minimal waste and no clogging compared to conventional coating techniques.

Ultrasonic spray produces droplets with very little variation in size, providing very uniform, thin layer coatings. This results in a much Faster ROI than conventional spray systems.
