20kHz 3000W Pneumatic Ultrasonic Welding Machine

The TEC-M2030J is a 20kHz 3000W pneumatic ultrasonic welding machine designed for small-to-medium-sized 

plastic assemblies, with application-specific horns and fixtures.

The system combines a digital auto-tuning generator, touchscreen parameter control and application-specific

horn and fixture design. Before equipment selection, TIMEAST can evaluate your part material, weld joint 

and production requirements through sample testing.

Key Features & Benefits

• Rigid Square-Column Structure

  The square-column support provides a rigid foundation for the welding head, helping maintain

  alignment under welding pressure.

• Linear Guide for Smooth Head Travel

  A linear ball guide supports smooth vertical movement of the welding head during each cycle.

• Digital Position Fine Adjustment

  Fine-tune the welding head position with a digital position readout for easier horn and fixture setup.

• Adjustable Ultrasonic Amplitude

  Adjust the output amplitude to suit the material, joint design, and welding requirements of

  small-to-medium-sized plastic parts.

• Automatic Frequency Tracking & Parameter Display

  The digital generator automatically tracks the operating frequency. Output current, power, and frequency

  are displayed to support setup and process monitoring.

Technical Specifications

Equipped with a self tuning digital generator for instant frequency tracking and stable amplitude output.

Is a 20kHz 3000W Ultrasonic Welder Right for Your Application?

A 20kHz 3000W ultrasonic welder is a common choice for medium-to-large thermoplastic parts requiring

higher welding power. The best configuration still depends on part size, material, weld area, joint design, 

and process requirements.

Frequently Asked Questions

Is the ultrasonic horn included with the machine?

The horn is customized for each product. Whether it is included depends on the final quotation 

and project scope.

Can one machine weld several different products?

Yes, if the products are suitable for the same frequency and machine capacity. Different products

normally require different horns, fixtures, and recipes.

What information do you need to design the horn and fixture?

We normally need the part drawing or 3D file, plastic material, weld joint design, samples if available, 

and the required welding result.

When should I choose a servo ultrasonic welder instead of this pneumatic model?

Choose servo when the application requires more precise control of position, speed, displacement,

 or process consistency. Pneumatic models are suitable for most standard welding applications.

Can this machine be integrated into an automatic production line?

Yes. It can be integrated with PLCs, robots, sensors, vision systems, loading systems, and other 

automation equipment.
