Product Summary
The UAM4000 is designed for precision ultrasonic spray coating of medical devices, particularly drug-eluting stents and balloon catheters. It features dual-mode customization for stent and balloon, enabling micron-level coating thickness control, 360° rotary tooling for complete coverage, and low-temperature atomization to preserve drug bioactivity. The system is compatible with various pharmaceutical solvents and polymer liquids, and meets Class 1000 cleanroom standards, FDA and ISO 13485 compliance.
Precision Coating
Adjustable coating thickness from 0.01-0.1 mm (stent mode), with 360° rotary tooling ensuring complete coverage without dead angles.
Low-Temperature Atomization
Ultrasonic atomization without high-pressure airflow protects drug bioactivity, preventing bridge deformation and substrate swelling.
High Material Utilization
Closed-loop spray system reduces pharmaceutical raw material loss by up to 60%, with liquid adhesion rate exceeding 90%.
Dual-Mode Flexibility
Bespoke customization for stent and balloon modes, supporting global and localized stripe coating for balloons.
