Q:Why choose ultrasonic welders?

A.It is cost effective, as it shortens manufacturing time.

B.It is environmentally-friendly, as no solvents, adhesives or any other reagent is needed.

C. It improves the quality of the products.

D. It ensures safety in production.


Q:Is ultrasonic harmful to the human body?

No. Ultrasonic is a mechanical wave, and when it is propagating, the energy will concentrate on the same specific direction, and it will not cause harm to human body.


Q: What logistic forwarder do you usually work with?

A: We work with EMS, TNT, UPS, FEDEX and other logistric forwarders. Assigned your own forwarder for shipment is available.


Q:How to choose the Frequency of ultrasonic welders?

A:The material and size and other factors will be taken into consideration.

Please contact us, we will recommend the suitable machine according to your products.


Q:Can you make customized horns (sonotrodes and fixtures) ?

A:We can make the customized horns according to your plastic parts.


Q: What‘s your warranty terms?

A:Machines for one year,generator for half a year,horn and transducer for three months.


Q:What‘s the lead time?

A:If only conventional models, usually 3~10 working days. If customized mold required, it needs negotiate.
