Stent Coating System

UC410 is an precision spray coating system for implantable stents, especially for aterial stents by using patented ultrasonic spray coating technology. It can penetrate complex stent geometreis, ensure full covrerage of all surfaces without webbing, save spray material, etc. UC520 is an advanced ultrasonic spray coating system for peripheral stents. The special design of system can process the stent as long as 280mm. Siansonic who has abundant experience on coatings of implantable medical device such as drug stents, drug balloon catheters, offers completed turn-key solutions for customers.  


  • Patented ultrasonic spray nozzle, precision liquid delivery.

  • Uniformity: <5%

  • Transfer efficiency of material: >95% (4-5 times higher than pressure spray)

  • Special stent holder design for easy and fast loading of stents.

  • Stent length: <40mm (Extensible function: for peripheral stent: <280mm)

  • Full digital precision ultrasonic generator: closed loop control strategy provides highly stable operation, with power control accuracy: 0.01W.
