This ultrasonic medical stent coating system is an ultrasonic spray‑coating unit designed to apply anti‑restenosis polymers and plasticizers onto implantable balloon catheters.

The system is primarily composed of an X+U‑axis high‑precision motion module, an integrated program editing platform,FUNSONIC ultrasonic spray nozzles, and high‑precision constant‑flow syringe pumps together with a digital carrier‑gas control system. Optional functional modules including ultrasonic dispersion liquid feeding and substrate heating are also available.

Featuring a compact, streamlined layout and full‑featured configuration, this equipment is engineered for enterprises, universities and research institutions engaged in vascular stent manufacturing using ultrasonic spray‑coating technology.

The X‑axis governs horizontal travel of the ultrasonic nozzle, delivering positioning accuracy down to 0.01 mm. The U‑axis enables 360° rotation of the stent substrate, ensuring uniform deposition of micron‑sized ultrasonically‑atomized droplets across the vascular stent surface. Liquid delivery is regulated by a high‑accuracy constant‑flow syringe pump, enabling precise, repeatable control over coating thickness.

 

 

 

 

1. Excellent Stability

Constructed with high-performance titanium alloy and stainless steel, the equipment delivers robust structural stability, outstanding adaptability and superior corrosion resistance. It operates under zero pressure with no running noise, effectively preventing nozzle clogging and material buildup. Meanwhile, the device achieves highly uniform atomized particle size for consistent spraying performance.

 

2. Material Conservation & Environmental Friendliness

The ultrasonic spraying process features minimal spray impact and zero liquid splashing. It greatly reduces raw material waste and airborne pollution caused by overspray and rebound spraying. Compared with conventional two-fluid spraying technology, ultrasonic spraying boosts material utilization efficiency by more than four times.

 

3. Precise Controllability & Industrial Adaptability

The system supports accurate adjustment of atomization flow and stable low-flow continuous spraying. Its spray morphology can be easily controlled and shaped, and compatibility with spray manipulators further expands its industrial applicability. Flexible parameter combinations allow the atomization output to meet diverse production and process requirements for different scenarios.

 

4. Low Maintenance & Energy Saving

Liquid supply is realized via self-gravity feeding or low-pressure pump delivery, enabling both continuous and intermittent atomization. The nozzle structure contains no moving or wearing parts, resulting in zero clogging, zero operational noise and zero working pressure during operation. No cooling water is required for atomization work. Featuring simple equipment structure, low power consumption and extremely low failure rate, the ultrasonic spray nozzle is self-cleaning and requires no daily routine maintenance, greatly reducing post-operation maintenance costs and workload.
