Automated Ultrasonic Drug-Coated Balloon & Stent Spray Machine

Key Features:

· Specialized ultrasonic spray equipment for drug-coated balloons (DCBs) and peripheral stent coatings

· Proprietary ultrasonic spray heads with precise drug dosage control

· Multi-target simultaneous coating capability to enhance production efficiency

· Patented aerosol humidification technology for accelerated drug crystallization

· Flawless coatings (no adhesion issues, pinholes, or defects)

· Exceptional uniformity, stability, and consistency

· High corrosion resistance, compatible with diverse organic solvents

System Overview:

A dedicated ultrasonic spray system for applying drug coatings to balloon catheters and peripheral stents. Equipped with TMAX’s focused-flow or micro-flow ultrasonic spray heads, it enables precision coating with uniform thickness and defect-free surfaces (no pinholes/orange peel effects). Compatible with coronary/peripheral balloons and stents via customized fixtures and rotation mechanisms.

Technical Highlights:

1. Ultrasonic Spray Head

o Proprietary designs (micro-flow/focused-flow) for minimal spray width (1–10mm) and ultra-low flow stability

o 4–5× higher material transfer efficiency vs. pneumatic spray

o 85%+ material utilization rate (4× better than traditional two-fluid spray)

2. Coating Quality

o Uniform drug deposition

o Defect-free layers

o High inter-batch consistency

3. Process Efficiency

o Multi-head/multi-fixture configurations for parallel processing

o Rapid-load balloon fixtures (supports catheters up to 2m)

o Peripheral stent fixtures for varied sizes

4. Humidification System (Optional)

o Submicron aerosol technology accelerates crystallization

o Non-invasive to equipment internals

5. Motion Control

o Servo-driven spray head positioning (µm-level accuracy)

o Dual-motor synchronous rotation (up to 500 RPM)

6. Compatibility

o Solvents: Acetone, THF, DMAC, Chloroform, Toluene

o Polymers: PU, PC, Silicone, Styrene, etc.

7. Key Parameters

o Balloon max length: 280mm

o Stent capacity: ≤280mm length, ≤60mm diameter

o Flow rate range: 0.001–2mL/min (solvent-dependent)

o Ultrasonic control: 0.01W precision (multi-core DSP)

8. Ancillary Systems

o Self-cleaning spray heads (anti-clogging)

o Ventilation interface (compatible with lab/extraction systems)

o Touchscreen HMI with intuitive GUI

o Optional UD25 Ultrasonic Dispersion Feeder: Prevents nanoparticle agglomeration
