Specialty Nozzles High Frequency Vibration Ultrasonic Technology

Hangzhou Shengtu Technology Co., Ltd. is one of the leading manufacturers and suppliers of specialty nozzles high frequency vibration ultrasonic technology in China. Welcome to buy high quality customized products at low price from our factory. Contact us for more details.

High‑frequency‑vibration specialty nozzles leveraging ultrasonic technology are critical for coating medical blood collection tubes and injection device inner walls. For silica coating applications, ultrasonic spraying deposits silica material onto tube surfaces to achieve superior thin‑film formation.

Driven by nozzle ultrasonic vibration, silica agglomerates are broken down, enabling uniform, well‑controlled silica coatings on tube walls. The fully automated process delivers significant improvements in product quality and production throughput.

FUNSONIC focuses on complete solutions and turnkey equipment for ultrasonic precision‑spraying processes. A full range of atomizing nozzles with varied frequencies and specifications are available to satisfy diverse product‑coating requirements. Customers are welcome to contact us for further inquiries.

An ultrasonic nozzle is fitted with a piezoelectric transducer that generates high-frequency vibration once energized. The structural arrangement of the transducers drives the nozzle to produce longitudinal vibration, creating thousands of vertical reciprocating vibrations at the nozzle tip every second. When a thin liquid film covers the tip of the activated ultrasonic nozzle, uniform capillary waves form across the liquid surface.

The amplitude of these capillary waves is precisely adjustable via the ultrasonic generator. As the amplitude increases to a critical threshold, the standing waves can no longer sustain their structural stability. The continuous intense stretching of the standing waves ultimately breaks apart the liquid film, generating highly uniform micrometer-sized droplets. With optimal operating parameters, stable and sustained atomization can be achieved for extended periods.

First introduced for industrial use in the 1970s, ultrasonic nozzles still adhere to the same core working principles to this day. Continuous technological advancements have expanded the range of available operating frequencies, while innovative integration methods have enabled ultrasonic spray systems to adapt to rigorous working environments, including spray pyrolysis, chemical vapor deposition (CVD), and vacuum processing conditions.
