FAQ

What is a double heads ultrasonic welding machine?

A double heads ultrasonic welding machine uses two ultrasonic welding horns that can 

 operate simultaneouslyor independently to improve throughput and welding consistency.

What materials can it weld?

It is suitable for a wide range of thermoplastics including ABS, PP, PC, PE, PS, PVC and more.

Why choose double heads instead of single head? 

Dual heads can weld multiple points at once, doubling efficiency and reducing cycle time for 

high‐volume production.

How is ultrasonic welding different from traditional welding?

Ultrasonic welding uses high-frequency sound waves to generate heat at the material interface,

 joining parts without adhesives or external heat sources.

Can this machine be customized?

Yes — parameters, fixtures and control options can be customized for different product 

 applications and production line integration.
