Substrate Coating

Sonaer nozzles can be utilized to coat a variety of substrates with a variety of liquids, solutions, suspensions, emulsions, etc. for various applications. Automated robotic coating systems allow for precise, accurate, reproducible, and repeatable coatings of substrates, in single, batch, or continuous process settings. Automation combined with hypo-needle feed attachments allow for multiple materials to be used in a coating during a single run, whether sequentially, simultaneously, or otherwise, allowing for graded coatings or bondcoats, or potentially even single nozzle use for multilayer coatings, which may be particularly useful for photovoltaic or solid oxide fuel cell applications. Such automated systems may even be utilized for spray based 3D printing of hydrogels or polymers from solution precursors and bioprinting, as well as for medical diagnostic and test substrates or other coatings of biomedical interest such as those for medical stents, catheters, or biomedical implants. Sonaer ultrasonics builds and develops automated coating systems from the laboratory and benchtop scale up to production level.

For precise prints or deposition, line widths down to ~250um under low flow conditions with Sonaer dual microfeed tube setup for spray shaping.

Sonaer makes custom-tipped fluoro nozzles which may be useful for cleaning and etching applications utilizing corrosives, acids, bases, or strong solvents.

Sonaer wide spray nozzles coupled with dove tail spray shapers can be used in series to coat wide substrates, such as solar panel glass or fabrics.

Sonaer radial spray and extended tip wide spray nozzles may be useful for coating the inside of tubular structures such as well plates or blood collection tubes.

Sonaer high-temperature nozzles can be utilized to coat heated substrates, over heated surfaces, or substrates inside heated chambers. These nozzles can also be coupled with pin-point or wide vortex spray shapers, to better guide, focus, or disperse sprays depending on substrate size and customer goals.

Moreover, Sonaer AACVD systems can be utilized to coat substrates with thin films or nanostructures, particularly for electronic, sensor, and photovoltaic applications.

Sonaer high-temperature atomizer nozzles spray consistent droplets on heated surfaces to form uniform coatings. Nozzles provide a narrow size distribution of droplets, making them the best choice for clean, accurate thin films. Nozzle can be purchased separately or integrated into our robotic coating system.

The atomizer nozzle fits directly into this attachment, which uses a small gas flow focus droplets to a pin point. Liquid passes through the center orifice of the nozzle and is atomized at the tip. Gas surrounds the droplets, giving a spray with a sharp focal point.

Sonaer flat spray attachment provides coverage in a rectangular area. The shaper spreads droplets in a consistent thin uniform direction with very little overspray. Thickness is nano to microns and is adjusted by the scientist for the application being developed.

Sonaer wide vortex spray attachment uses a small gas pressure to coat large areas with low volume of droplets. Droplets are dispersed over a wide area and provide a thin uniform coverage.
