Float Glass Coating
In the float glass industry, Sono-Tek systems apply anti-stain and protective materials that extend storage life, reduce waste, and protect functional glass—such as Low-E (low-emissivity) glass—from scratches. The controlled micron-level coating uniformity achieved through our ultrasonic spray nozzles helps maintain long-term surface integrity and product consistency.
Functional Coatings
Sono-Tek equipment is used to apply thin functional coatings on glass used in electronic devices and a wide range of industrial components, including photoresist onto lenses, conductive films, and other precision coatings. Our atomization process allows manufacturers to deposit uniform thin layers onto delicate or heat-sensitive substrates—ideal for displays, sensors, and touch panels.
Protective Coatings
For anti-corrosion, shock and vibration resistance, abrasion resistance, anti-fog, and anti-static protection, Sono-Tek’s ultrasonic spray coating systems produce smooth, even coatings that enhance durability without excessive overspray. The process supports a wide range of coating materials—typically low-viscosity liquids—ensuring consistent adhesion and long-term protection.
Vacuum Chamber Deposition
Sono-Tek offers a unique line of ultrasonic spray nozzles and liquid-feed integration technology specifically designed for use in vacuum deposition systems, where precise atomization under vacuum conditions supports the formation of thin, uniform layers. Our non-clogging design ensures reliable performance in low-pressure, high-purity environments.
Lenses
Sono-Tek’s spray technology is used for coating high-performance lenses and optics with anti-reflective, hydrophobic, photoresist, and scratch-resistant films. The system’s nano- to micron-level control enables excellent film quality across complex lens geometries.
Automotive
In the automotive industry, Sono-Tek provides coating and thin-film atomization systems for components such as sensors, heads-up displays, headlight lenses, and other high-performance hardware. Our process ensures uniform, high-adhesion films that enhance functionality, appearance, and environmental resistance.
Aerospace / Aviation
Sono-Tek’s precision ultrasonic spray nozzles are trusted for aerospace applications requiring highly controlled micron-thin coatings. These systems provide consistent coverage with minimal waste—ideal for performance-critical components and advanced materials. Our coating solutions commonly enable the precise application of specialized thin-film coatings on high-performance hardware, helping protect critical components and assemblies from extreme environmental and electrical stresses.
Aluminum Flux Brazing
Sono-Tek offers ultrasonic spray coating systems designed specifically for aluminum flux brazing, including the SonoBraze 215. This system provides uniform flux coatings for aluminum brazing applications such as heat exchangers and radiators. The process improves bond reliability, reduces overspray, and ensures consistent coverage across complex geometries. It has been shown to reduce flux consumption by more than 50%, with significant reductions in maintenance and the elimination of clogging nozzles typically associated with paint flux.
Advanced Textiles
Sono-Tek coating machines enable the deposition of nanomaterials and functional finishes onto textiles, producing advanced properties such as water repellency, conductivity, and antimicrobial protection. The uniform, low-viscosity coatings maintain breathability and flexibility for next-generation fabric technology.
Injection Mold Release
Sono-Tek’s ultrasonic spray technology provides a clean, efficient alternative to conventional mold-release methods. By delivering uniform micron-level coatings at ultra-low flow rates, Sono-Tek systems minimize waste, improve surface finish, and enhance mold longevity.
Food Manufacturing and Packaging
Sono-Tek systems are used in food manufacturing and packaging processes to apply ultra-thin, uniform layers of functional coatings such as release agents, antimicrobial treatments, and protective barriers. These precision-applied films prevent sticking, enhance product handling, and help extend shelf life by inhibiting microbial growth. The non-clogging ultrasonic spray process ensures consistent coverage, product safety, and efficient material use across high-speed production environments.
Solder Powder
Sono-Tek’s atomization systems convert molten solder into uniform micron-sized particles with a tight size distribution, ideal for powder metallurgy and electronic solder applications. Beyond solder, these specialized ultrasonic nozzles are also used for atomizing other high-temperature and specialty liquids—including molten waxes and selected alloys—supporting advanced material development and custom production processes. Our precise liquid delivery control ensures consistent particle quality, process stability, and production efficiency across a wide range of molten materials.
Through these technologies, Sono-Tek partners with manufacturers to deliver reliable, scalable, and non-clogging ultrasonic spray coating systems that advance innovation across glass, energy, and industrial markets.
