Rotary Indexing Ultrasonic Welding System

Introduction

This rotary ultrasonic welding system is designed for automated plastic assembly

 using a multi-station rotary indexing table. Parts are positioned on the rotary table

 and move step-by-step through loading, welding, and unloading stations, ensuring

 stable and efficient production.

Equipped with a PLC + HMI control system, the machine automates welding, indexing, 

and unloading processes. Operators only need to perform manual loading, significantly 

reducing labor requirements while maintaining consistent weld quality and production efficiency.

How Rotary Indexing Ultrasonic Welding Works

This system uses a rotary indexing table to transfer parts between multiple stations. 

The ultrasonic welding unit is installed at a fixed station, where welding is performed

during each indexing cycle.

As the table rotates step-by-step, different operations such as loading, welding, and 

unloading are carried out simultaneously at separate stations. This multi-station design

enables parallel processing, reduces idle time, and ensures a smooth production rhythm.

How Multi-Station Design Improves Your Production

With multiple stations working simultaneously, the system eliminates waiting time 

between operations. While one part is being welded, another part can be loaded or

unloaded at a different station.

This parallel workflow significantly reduces cycle time, increases throughput, 

and maximizes equipment utilization, making it ideal for high-volume manufacturing 

environments.

Applications

This rotary multi-station ultrasonic welding system is suitable for welding a wide range of

 thermoplastic materials, including ABS, PP, PE, PS, PC, and nylon.

Single Station vs Rotary Multi-Station Ultrasonic Welding

Single Station Welding

• One process at a time

• Longer cycle time

• Lower production efficiency

Rotary Multi-Station System

• Parallel processing at multiple stations

• Shorter cycle time

• Higher output and stable quality
