What SONO-Tek Corporation does
Sono-Tek Corporation (NASDAQ: SOTK), founded in 1975 and headquartered in Milton, New York, designs and manufactures ultrasonic coating systems used to deposit precision thin films in industrial and medical manufacturing processes. The company's core technology is its patented ultrasonic nozzle, which atomizes coating fluids into a fine, uniform spray through high-frequency vibration rather than pressurized atomization, enabling highly controlled deposition of functional materials onto substrates. Sono-Tek is the recognized inventor of ultrasonic spray fluxing for printed circuit board (PCB) assembly and holds what it describes as the largest installed base of stent coating machines globally. Its product portfolio spans stand-alone ultrasonic nozzles, multi-axis programmable coating systems, and fully integrated in-line production lines, with applications in medical devices (drug-coated stents, diagnostic devices), solar/photovoltaic manufacturing, electronics packaging, and laboratory research.
The company's revenue model is primarily capital equipment sales of coating systems, augmented by recurring revenue from nozzles, replacement parts, and process engineering services across its installed base. Go-to-market combines direct sales to large OEM and medical device manufacturers with OEM integration partnerships, most notably an exclusive agreement with BUCHI for laboratory spray drying equipment and embedded integration with virtually all major wave solder manufacturers for PCB fluxing. End-market exposure is diversified across medical, solar, electronics, and laboratory research, with FY2026 (year ending February 2026) revenue of approximately $20.9M, gross margins of 51%, and a $2.8M order from a major US medical device manufacturer, an $820K diagnostic device order, and a $5.9M multi-system order from a major solar customer representing the largest disclosed transactions. The company employs 101-250 people and has demonstrated consecutive years above $20M in revenue, with medical segment sales growing 150% year-over-year in Q2 FY2026.

Product offeringCore offering
SONO-Tek Corporation manufactures ultrasonic coating systems and replacement ultrasonic nozzles used to apply uniform, precision thin-film coatings onto parts and substrates. Its product range spans bench-top laboratory units, standalone programmable coaters, fully automated inline production systems, and ultrasonic spray drying packages, sold primarily to industrial manufacturers across medical device, alternative energy, electronics, semiconductor, glass, textile, and food packaging end markets.
Product overview
SONO-Tek Corporation is a developer and manufacturer of ultrasonic coating systems that provide precision thin-film deposition for R&D through high-volume production. The product portfolio centers on proprietary ultrasonic spray technology using low-velocity atomization to deposit uniform coatings with minimal waste. The core product line includes the FlexiCoat family (FlexiCoat, FlexiCoat MAX, FlexiCoat FC-LAP), ExactaCoat benchtop systems, VersiCoat conveyorized platforms, and the high-volume Industrial WideTrack systems for wide-area web coating. For medical device manufacturing, the MediCoat product line serves stent coating (DES3000/4000), balloon catheter coating (BCC), peripheral stent coating (PSI), and blood collection tube coating (MedXT Series). The OMNIbot provides six-axis robotic coating for complex 3D surfaces. These systems are supported by a comprehensive line of ultrasonic nozzles (MicroMist, AccuMist, Impact, Vortex, PicoMist) and liquid delivery accessories (SonicSyringe, MicroFlow, SonoFlow Fusion). The company also integrates its technology into OEM platforms including wave solder machines and BUCHI spray dryers.
