Ultrasonic Battery Lid Welding Machine – Effective Solution from VietSonic

1. Introduction to Ultrasonic Welding Technology

An ultrasonic welding machine is a device that utilizes high-frequency ultrasonic vibrations (typically 20kHz – 35kHz) combined with pressure to create welds between plastic or thin metal surfaces, completely without the need for auxiliary materials such as glue or screws.

This technology is increasingly applied in industrial manufacturing, especially in the battery manufacturing industry – where high mechanical strength, electrical conductivity, and airtightness are required.

2. Application of VietSonic Ultrasonic Machine in Battery Lid Welding

In the actual video from VietSonic, the ultrasonic welding machine is used to weld the plastic lid of the battery, helping to tightly bond plastic parts, ensuring tightness and durability after welding.


Outstanding Product Features:

  • High weld quality, leaving no burrs/flash, ensuring airtightness and preventing acid leakage;
  • Does not melt the entire material, helping to maintain the battery lid structure;
  • Fast welding speed of only 0.5–2 seconds/weld, suitable for mass industrial production;
  • Stable operation, high machine durability, easy integration into automated lines.

3. Outstanding Advantages of VietSonic Ultrasonic Machines
