Ultrasonic Welding Transducers – 15, 20, 35 & 40 kHz

Ultrasonic Transducers for Welding Systems

An ultrasonic transducer, also called an ultrasonic converter, converts electrical energy from the generator 

into mechanical vibration. This vibration is transmitted through the booster and welding horn to the workpiece.

TIMEAST supplies transducers for ultrasonic plastic welding machines and customized automation equipment. 

For replacement applications, we review the existing system specifications and installation details to help 

identify a suitable configuration.

Available Configurations

Please contact us to confirm the available power rating, dimensions and ceramic options for your required frequency.

Piezoelectric Ceramic Options

Piezoelectric ceramics are the active elements inside an ultrasonic transducer. TIMEAST offers Chinese-made 

and Japanese-imported ceramic options for selected configurations.

Please specify your preferred ceramic option when requesting a quotation. We will confirm availability and 

the proposed configuration based on your equipment requirements and budget.

If you are replacing an existing transducer, please also provide any available information about its original 

ceramic specification.

The products shown are examples. The supplied configuration will follow the specifications confirmed 

in your quotation and order.

Replacement Transducer Matching

Looking for a replacement transducer for your existing welding machine? Please send the following information:

• Clear photos of the transducer and its nameplate

• Operating frequency and rated power

• Overall dimensions and mounting details

• Connecting thread size

• Electrical connector or cable details

• Generator brand, model and specifications

• Photos or drawings of the connected booster and welding horn

Matching frequency alone does not confirm compatibility. Electrical characteristics, mechanical connections 

and the complete ultrasonic assembly must also be considered.

If the original drawing is unavailable, send clear photos and the measurements you can obtain. We will review 

the information and advise whether additional details or a sample are needed.

Transducer and Welding Horn Supply

We can supply a transducer individually or together with a matching welding horn.

For a customized horn, please provide a detailed drawing showing its dimensions, connecting interface 

and working-surface pattern, including any grooves or knurling.

If no drawing is available, please describe your application and specific requirements. Photos, workpiece drawings 

or samples can help us review and design the horn structure.

Frequently Asked Questions

What frequencies are available?

We supply ultrasonic welding transducers in 15, 20, 35 and 40 kHz configurations. Power ratings and dimensions 

depend on the selected model.

Can I choose Chinese-made or Japanese-imported ceramics?

Yes. Both options are available for selected configurations. Please state your preference so we can confirm availability 

and include the correct option in your quotation.

Can your transducer replace the one in my existing machine?

Suitability must be reviewed against your existing system. Please send the transducer specifications, photos, 

installation dimensions and generator information. The same frequency does not automatically mean the components 

are interchangeable.

Can I order a transducer with a welding horn?

Yes. We can supply a transducer-and-horn set. Please provide the horn drawing, especially its dimensions and 

working-surface pattern. If no drawing is available, send your specific requirements for design review.

What are the minimum order quantity and lead time?

The minimum order quantity and lead time depend on the model, quantity and customization requirements. 

These will be confirmed in your quotation.

Discuss Your Ultrasonic Horn Requirements

For a new horn or a replacement, please provide:

• Part drawings or photos showing the welding area

• Plastic material and required weld result

• Machine brand, model and operating frequency

• Booster connection details or an existing horn drawing, if available

For replacement horns, describe any cracking, marking or inconsistent welding. 

Matching frequency alone does not confirm compatibility.
