Ultrasonic spraying is a uniquely advantageous technique, characterized by high uniformity in sprayings, efficient use of materials, precise control over spraying thickness, and no clogging of the nozzle. The ultrasonic nozzle, the heart of ultrasonic spraying, is tailored for various applications. Among these, the X series nanomist ultrasonic nozzle, with its special fluid and air supply methods, offers a smaller spray area and more precise flow control, making it suitable for small-scale spraying applications.

Beyond its minimal spray area and volume, the nomist ultrasonic nozzle is a typical external feed nozzle. The solution to spray is atomized outside and delivered directly to the ultrasonic nozzle, ensuring higher precision in fluid supply and more stable atomization. This significantly reduces the impact of ultrasonic processes on certain spray liquids. For instance, in applications involving polymer solutions, temperature can affect polymers, altering their state and, consequently, the spraying outcome. The X series ultrasonic nozzle effectively mitigates this impact, ensuring an ideal spray effect.
A typical application of the X series ultrasonic nozzle is the spraying of drug-eluting stents, particularly for small-scale stents such as coronary and intracranial stents. Ultrasonic spraying exhibits clear advantages in the precision of drug dosage control and the uniformity of the drug spraying. These benefits are achieved through repeated spraying processes that ensure uniform, dense surface spraying free of adhesion, pinholes, and bubbles.
Siansonic Technology, with nearly 40 years of experience in the ultrasonic industry, offers a wide range of ultrasonic products including ultrasonic nozzles, ultrasonic spray system, sensors, and transducers. The drug-eluting stent spraying system from Siansonic Technology, equipped with its proprietary nanomist ultrasonic nozzles, is extensively used for spraying various anti-restenosis drugs on drug-eluting stents.
