20KHZ 3000W Ultrasonic Wire Splicing Machine

Wire harness ultrasonic welding machine joining technology is widely used to produce reliable electrical connections in the automotive industry as well as in other areas.

The XIAOWEI 20KHZ 3000W wire ultrasonic welder machine with its intuitive touch screen operation and lightweight, compact design is ideally suited to small soldered joints, such as cable harnesses on assembly boards.

Ultrasonic Wire Splicing Machine

XW ultrasonic wire splicing machine is a tried-and-tested, sophisticated wire welding system. It is perfect for small welded splices and its light-weight and compact design makes it ideal for portable applications such as cable harnesses on assembly boards. It can also be used in preproduction and is available in a variety of table-top and standing table configurations. The machine features highly intuitive touchscreen operation. Jobs, splices and sequences can be defined easily on the screen or loaded via the data interface. Alongside the standard limit value monitoring, a bad parts cutter, anti side-splice accessory, wire stops and a user and rights management system help guarantee the highest level of quality.

Quality, process reliability and flexibility are the hallmarks of good wire harness production. Our technologically leading machines enable you to achieve these characteristics for your production lines. The Minic series covers almost the entire cross-section range in the cable harness (from 0.26 mm² to 30 mm²) - without tool changes or mechanical modifications. It is suitable for welding aluminium, copper and mixed joints with cross-sections up to 50 mm². It was specially developed for large cross-sections up to 200 mm². Connections of lines with various terminals, such as MAK or MAS, are also possible. All machines are suitable for welding mixed aluminium-copper joints - without modifications or tool changes.


1.Lowest costs per splice
2.Safe and reliable process
3.User-friendly and simple operation
4.Intuitive software on a touchscreen interface
5.Durable tools, quick tool changes

Working Principle

The ultrasonic welding process converts electrical energy into mechanical vibrations causing the metals to join. In the ultrasonic stack, the converter transmits the energy through the booster causing the horn to vibrate. The converter is made up of piezoelectric ceramic disks that expand and contract at the same frequency of applied electrical energy. The booster increases or decreases the amplitude of the vibrations to provide the optimum amplitude for the material, size and type of assembly.


Ultrasonic joining technology is widely used to produce reliable electrical connections in the automotive industry, as well as in a broad range of other fields. The benefits of ultrasonic wire splicing include lower electrical resistance, improved cost efficiency and a high level of protection against corrosion.
Typical applications include wire splicing in preproduction and wire harnesses on assembly boards or the compaction of wires. Copper-to-copper and copper-to-aluminum combinations can be welded with the same machine.
