FAQ / Tips

Q1: How to select the right ultrasonic frequency for automotive parts?

A1: Small and precise parts like sensors typically use 20kHz, while larger panels may require 

15kHz or higher-power machines for optimal joint strength.

Q2: Which materials are suitable for ultrasonic welding in automotive applications?

A2: Common thermoplastics like ABS, PP, PC, and PC/ABS blends work well. Materials with 

fillers or additives may require parameter adjustments.

Q3: How does ultrasonic welding compare to adhesive or heat welding?

A3: Ultrasonic welding is faster, cleaner, produces stronger joints, and avoids adhesives or heat damage,

 improving both efficiency and quality.
