Customer FAQs
Why does my ultrasonic booster overheat?
Your ultrasonic booster likely overheats due to: frequency mismatch (using the wrong kHz rating), excessive amplitude (beyond its designed ratio), or poor cooling (lack of airflow/water cooling). Other causes include loose mounting (vibration friction), material cracks (fatigue from prolonged use), or contaminated surfaces (dirt/oil disrupting energy transfer).
What is an ultrasonic booster and how does it work?
An ultrasonic booster is a metal component that amplifies or reduces vibration amplitude between the transducer and welding horn. It works by altering the cross-sectional area ratio (e.g., 1:2 ratio doubles the amplitude) at the same frequency (15-40kHz).
How to calculate booster amplification ratio?
Ratio = Output Amplitude ÷ Input Amplitude. Example: 30μm input → 90μm output = 1:3 ratio
How to test if an ultrasonic booster is damaged?
Perform:
✅ Visual inspection (cracks/discoloration)
✅ Frequency scan (deviation > ±0.5kHz = faulty)
✅ Amplitude measurement (uneven output = internal fatigue)
Can I use one booster for different ultrasonic welding applications?
Not recommended. Each booster is tuned for specific:
🔧 Amplitude ratio
🔧 Frequency (15/20/30/40kHz)
🔧 Material (titanium for high power, steel for durability)
What’s the difference between a booster and a horn?
Booster: Modifies amplitude (mounted between transducer & horn)
Horn (Sonotrode): Directly contacts workpiece for welding
