15kHz vs 20kHz Ultrasonic Welding Machine

Understanding the difference helps you choose the right machine:

15kHz Ultrasonic Welding Machine:

• Higher power output

• Deeper weld penetration

• Suitable for large and thick plastic parts

• Stronger weld strength

20kHz Ultrasonic Welding Machine:

• Medium power

• Higher precision

• Suitable for small to medium parts

• Better for delicate components

●Simple rule:

Large parts → choose 15kHz

Small precision parts → choose 20kHz
