Introduction

Ultrasonic transducers, also known as converters, are the core components of 

ultrasonic welding systems. They convert electrical energy into high-frequency

mechanical vibrations, which are then transmitted to the welding interface through the horn.

The performance of the transducer directly affects welding stability, energy efficiency,

 and weld quality, making it a critical factor in plastic welding applications.

Our ultrasonic transducer is compatible with a range of ultrasonic horns and generators 

to deliver precision welding for plastic components.

Multi-Frequency Capability

Our ultrasonic transducers are available in multiple frequency options, including 

15kHz, 20kHz, 28kHz, 35kHz, and 40kHz, ensuring compatibility with a wide range 

of ultrasonic welding systems.

Each transducer is precisely designed and tuned to deliver stable amplitude output,

efficient energy conversion, and reliable long-term performance across different

plastic welding applications.

Key Engineering Features

• High energy conversion efficiency

• Stable amplitude output for consistent welding quality

• Available in multiple frequency ranges (15kHz–40kHz)

• Durable structure for long service life

• Optimized for industrial plastic welding applications

• Reliable performance in continuous operation

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

reliability expectations for long-term operation.

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.

Compatibility & Integration

This ultrasonic transducer is compatible with a wide range of ultrasonic welding machines, 

including standard pneumatic systems, high-precision welding equipment, and automated 

production lines.

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 can assist with selecting the frequency and matching the full welding 

system configuration.

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

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 focuses on engineering-grade reliability for industrial manufacturing needs.
