High Precision 120khz Ultrasonic Spraying Nozzle Coating Machine for Metal Nanoparticles
Description
The High Precision 120kHz Ultrasonic Spraying Nozzle Coating Machine is an advanced nano-atomization system designed for ultra-fine and highly uniform coating of metal nanoparticle suspensions. Operating at an ultra-high frequency of 120kHz, the system generates extremely fine droplets at the nano-scale, enabling precise deposition of functional materials with exceptional uniformity and surface control.
Unlike conventional air-spray or low-frequency ultrasonic systems, this technology produces a much narrower droplet size distribution and significantly reduces overspray, making it ideal for high-value metal nanoparticle applications where coating accuracy and material efficiency are critical.
It is widely used in advanced electronics, energy materials, thin-film deposition, and precision functional coatings.
The system is equipped with a 120kHz ultra-high-frequency ultrasonic atomizing nozzle, enabling ultra-stable nano-droplet generation with extremely fine particle size control.
A key advantage is its ability to achieve true nano-level atomization, making it especially suitable for metal nanoparticle suspensions such as silver, copper, gold, and conductive inks used in high-end electronic applications.
Compared with traditional 20–60kHz systems, the 120kHz design provides smaller droplet size, higher coating uniformity, and significantly improved film smoothness, reducing defects in thin-film formation.
The low-pressure, non-contact spraying process eliminates nozzle clogging issues common in high-solid-content nanoparticle fluids, ensuring stable long-term operation.
The system supports precise control of flow rate, spray width, and ultrasonic energy output, allowing accurate adjustment for ultra-thin and high-precision coating requirements.
Its modular structure allows easy integration into automated production lines, laboratory research platforms, and pilot-scale manufacturing systems.
