Product Overview

The 20kHz Ultrasonic Welding Transducer from Timeast TEC is a core component for industrial

 ultrasonic plastic welding systems. It converts high-frequency electrical energy into stable 

mechanical vibration, supporting consistent weld quality, efficient energy transmission, and 

long service life in production environments.

A 15kHz high-power option is available for applications requiring increased welding force 

and deeper energy penetration. 35kHz is also available on request for precision welding applications.

Key Engineering Features

• Stable amplitude output with optimized piezoelectric ceramic stack

• High electro-mechanical conversion efficiency for effective energy transfer

• Frequency stability under load for consistent welding results

• Low heat generation during continuous operation

• Built for industrial duty cycle and long service life

Each transducer is assembled and tuned to meet welding system requirements and reliability expectations

for long-term operation.

Available Frequency Options

20kHz (Standard)

Recommended for most ultrasonic plastic welding applications with balanced performance and wide system

compatibility.

15kHz (High-Power Option)

Designed for high-energy welding tasks where stronger output and deeper vibration transmission are required.

35kHz (On Request)

Available for precision welding needs such as small parts, fine features, and certain electronics/medical applications.

Note: 20kHz and 15kHz are the primary configurations used in most industrial welding systems. 35kHz availability

depends on application requirements.

15kHz Configuration for High-Power Ultrasonic Welding

The 15kHz ultrasonic transducer configuration is widely used for high-power ultrasonic welding where greater 

welding energy and deeper vibration penetration are necessary. Compared with standard 20kHz systems,

the 15kHz option typically provides higher mechanical force output, which is especially helpful for welding:

• Thick-wall plastic parts

• Large-size components or larger welding areas

• High-strength or rigid thermoplastics

• Applications requiring high joint strength

If your parts are difficult to weld or require higher energy input, the 15kHz option can be a better engineering choice.

15kHz vs 20kHz (Engineering Perspective)

Choose 15kHz when you need:

• Higher power output for thick/large parts

• Deeper energy transmission through the joint area

• Stronger weld strength for structural components

Choose 20kHz when you need:

• Standard industrial plastic welding performance

• Broad compatibility with general welding setups

• Typical applications with small to medium part sizes

Timeast TEC can assist with selecting the frequency and matching the full welding system configuration.

Typical Applications

This transducer is suitable for ultrasonic welding in industries such as:

• Automotive plastic components

• Electronics housings and connectors

• Medical device plastic parts

• Household appliance assemblies

• Customized ultrasonic automation systems

It can be integrated into both stand-alone welding machines and automated production lines.

System Compatibility & Matching Support

The transducer can be matched with:

• Ultrasonic generators

• Boosters and sonotrodes (horns)

• Servo or pneumatic ultrasonic welding machines

• Customized automation welding systems by Timeast TEC

To improve welding stability and energy transfer efficiency, we provide system-level matching and

tuning support (transducer + booster + horn + generator).

Quality & Reliability

• Frequency and impedance testing before delivery

• Stable performance under continuous industrial operation

• Strict material selection and controlled assembly process

• Designed for long service life and consistent output

Timeast TEC focuses on engineering-grade reliability for industrial manufacturing needs.
