How to Properly Arrange Parts in an Ultrasonic Cleaner: Maximizing Efficiency & Avoiding Damage

Article Outline

1. The Science of Cavitation Distribution

• Cavitation energy density variations: 30% higher at liquid surface vs. tank bottom
• Dead zone identification: 5-8cm around transducer arrays
• Material-specific resonance: How part geometry affects energy absorption

2. 6 Fundamental Loading Principles

1. Separation Rule: Maintain ≥1.5× part thickness between components
2. Orientation Guidelines:
   • Cylinders: Vertical alignment (30% better bore cleaning)
   • Flat plates: 15° angle to tank walls
   • Threaded parts: Male/female threads disengaged
3. Weight Distribution: ≤0.8kg/L load density for optimal cavitation
4. Depth Control: Submersion depth = 2× part height + 3cm
5. Fixturing Solutions: Custom 3D-printed nylon racks vs. standard baskets
6. Sequential Loading: Heavy parts first, delicate components last

3. Industry-Specific Configuration Templates

4. Advanced Positioning Tools & Techniques

• Laser Alignment Systems: Achieve ±0.5mm positioning accuracy
• Computational Fluid Dynamics (CFD) Modeling: Predict cavitation coverage
• Magnetic Fixturing: For ferrous parts (12x faster setup)
• Rotary Cage Systems: 35% improvement in complex geometries
