Balloon Catheter Coating Ultrasonic Spray Coating Nozzle

Balloon Catheter Coating Nozzle

Unlike conventional spray nozzles that rely on pressure and high velocity motion to shear a fluid into small drops,the ultrasonic spray nozzle uses only low ultrasonic vibrational energy for atomization.It is widely used for ultrasonic spray coating and pyrolysis.The rate at which the liquid is atomized depends,within limits,solely on the volume that is being delivered onto the atomizing surface.Typically,the higher the frequency ,the lower the processing capability.The amount of material atomized can be as little as 1 μl/min.

The FocusMist Series Nozzles offer adjustable spray widths range (2mm-20mm), wide controlled flow rate range (0.02ml/min-10ml/min) and wide droplets size options (15um-40um). Compared with conventional pressure spray technology, they have significant advantages in a broad range of applications. The FocusMist Series is mainly designed for R&D applications and coatings onto other small area substrates such as fuel cell, sensors, stents, balloon catheters, touch screen, etc. Waste of raw material is significantly reduced, since the ultrasonic atomization can work well without high pressure air. As a result, the pollution due to VOCs is greatly reduced as well. In addition, maintenance is also much lower than conventional spray coating methods because ultrasonic nozzles don't clog.
