15kHz 4200W Ultrasonic Plastic Welding Machine

Is 15kHz 4200W Suitable for Your Plastic Parts?

A 15kHz 4200W ultrasonic welder is an option for larger thermoplastic assemblies, such as plastic housings 

and filter bodies, where the joint requires relatively high vibration amplitude and a suitably sized horn.

Why 15kHz? Lower-frequency systems can accommodate larger horns and higher-amplitude applications. 

Suitability still depends on the plastic material, part geometry and joint design—not part size or wall 

thickness alone.

Why 4200W? The generator needs enough power to maintain the required amplitude under welding load. 

Larger horns and demanding welds may require more power, but the 4200W rating alone does not guarantee

weld strength or an airtight seal.

Send us your material details, part drawings and welding requirements. Sample testing helps confirm the 

frequency, power and tooling needed.

Custom Ultrasonic Horn & Fixture

For large or complex plastic parts, proper horn and fixture design is essential for consistent welding results.

TIMEAST designs application-specific ultrasonic horns and fixtures based on your part geometry, welding area 

and production requirements.

For large or complex parts, we recommend ultrasonic welding sample testing before confirming the final horn, 

fixture and machine configuration.

Technical Specifications

*Actual welding time depends on the product, material, joint design and welding requirements.

Technical configuration and tooling can be customized according to the application.

15kHz or 20kHz Ultrasonic Welding?

A 15kHz ultrasonic system is often considered for larger components, larger welding areas or 

applications requiring higher available amplitude.

A 20kHz system is widely used for general plastic welding applications and smaller or medium-sized

components, you can explore our 20kHz 3000W ultrasonic welder .

However, frequency selection should not be based on part size alone. The appropriate frequency 

and power depend on the material, product geometry, welding area, joint design, horn dimensions 

and required weld result.

Why TIMEAST?

Application-Based Machine Configuration

We evaluate your plastic part, welding area and production requirements to recommend a suitable 

machine configuration.

Custom Horns & Fixtures

We design ultrasonic horns and fixtures around your product geometry to support reliable positioning

and consistent welding.

Sample Testing Before Production

Send us your part drawings or samples. Our engineers can evaluate welding feasibility and help confirm

the tooling and process requirements before ordering.

Do you offer servo-driven ultrasonic welding machines?

Yes. For applications requiring more precise control of welding position, force and weld depth, we also offer

15kHz and 20kHz servo ultrasonic welding machines . The final configuration depends on your part design 

and welding requirements.

FAQ

Can this machine weld my plastic part?

The TEC-1542M can be evaluated for a range of thermoplastics, including ABS, PC, PP, PE and PA (Nylon).

Actual weldability depends on the material grade, part geometry, joint design and tooling configuration. 

Why use 15kHz instead of 20kHz?

15kHz systems generally provide higher available amplitude and are often used for larger or more 

demanding welding applications. The final frequency should be selected according to the actual 

product and tooling requirements.

Can the ultrasonic horn and fixture be customized?

Yes. The horn and fixture can be designed according to the product geometry, welding area and 

process requirements.

Can the machine be integrated into an automated production line?

Yes. For applications requiring more precise control of welding position, force and weld depth, 

we also offer 15kHz and 20kHz servo ultrasonic welding machines . The final configuration 

depends on your part design and welding requirements.
