Customer Reviews
The converters corresponding to your INVOICE NO. HS2015021 work very well. We would like to order more

—— Peter

I'm very happy with your good communication skills as well as follow up and good deal. I will definitely inform you my further program for further coo

—— Vinay

We tested it and it worked.  I will let you know about future purchases soon.

—— Alvin

Thank you! It is a pleasure, to work with a company that wants to make it right for the customer :) many times i deal with Chinese companies that do not care about the customer and long term business. I think I made the right decision going with you and Altrasonic !!!

The principle of ultrasonic atomization spraying equipment

The ultrasonic atomization spraying equipment is composed of an ultrasonic transducer, an horn, an atomization head, and a driving power supply. The transducer drives the atomizing head to vibrate at high frequency, applying ultrasonic force to water or other liquids, breaking the flowing liquid into fine particles, and spraying them into the air, so as to achieve the purpose of spraying (atomization).


Ultrasonic spraying equipment is used in the manufacturing and spraying of display equipment, fuel cells, energy-based solar photovoltaic cells, lithium batteries, optical lens coating, medical equipment (medical implant device coating, blood vessel stent coating, blood collection tube coating) Among them, the more common ones are the surface coating of interventional medical devices and the spraying of electronic products.

Ultrasonic atomization spraying equipment uses ultrasonic transducers to convert high-frequency sound waves into mechanical energy, and then converts it into liquid, thereby generating standing waves. When the liquid leaves the atomizing surface of the nozzle, it will break into a fine mist of uniform micron-sized droplets.


It is different from the traditional nozzle which relies on pressure and high-speed motion to break down the liquid into small particles. The ultrasonic nozzle uses liquid ultrasonic atomization, and the ultrasonic vibration energy is low. The liquid can be delivered to the nozzle by its own weight or low-pressure liquid pump for continuous or intermittent atomization.


Unlike pressure nozzles, ultrasonic nozzles do not use high pressure to force liquid through small holes to produce a spray. The liquid is fed through the center of a nozzle with a larger orifice without pressure, and is atomized due to ultrasonic vibration in the nozzle. The nozzles of the liquid supply channels and holes are relatively large, so as to achieve non-clogging spraying.


The ultrasonic atomization spraying equipment can be equipped with a heating platform for the substrate, such as a heating plate. Multiple independently controlled syringes (paint solution containers) can be used to process different materials.
