The POLOS® UC510 is an advanced ultrasonic spray coating system developed for high-precision coating tasks in R&D, pilot production, and medical device manufacturing. While the platform supports a wide range of thin-film applications (including coatings for solar cells, fuel cells, and glass), the UC510 is purpose-built for uniform drug coating of balloon catheters.
Designed for drug-coated balloon technology
Utilizing patented ultrasonic spray technology, the UC510 delivers smooth, highly uniform coatings across the entire balloon surface without overspray or material buildup. The fine droplet formation enables excellent surface coverage while maximizing transfer efficiency, helping reduce material waste and improve process consistency.
Optimized for long and delicate substrates
The system’s dedicated mechanical design allows coating of balloon catheters up to 280 mm in length, making it suitable for both coronary and peripheral applications. A precision fixture securely supports the catheter during processing, while synchronized servo motion and dual motor rotation ensure even exposure from all angles.
Turnkey solution backed by medical coating expertise
Building on extensive experience with implantable medical devices such as drug-eluting stents and balloon catheters, POLOS® provides complete, application-ready coating solutions. Intuitive software controls and configurable process parameters allow users to tailor the system to specific drug formulations and coating requirements.
