Top 5 Best Ultrasonic Welding Machine in 2021

Top 5 Best Ultrasonic Welding Machine in 2021

15 Jul 2021

Most people will know what a normal ultrasonic metal welding machine. Most of us have even used ultrasonic welding machines. Ultrasonic welding machines are primarily important for joining two different types of materials.


This guide will take you through all the crucial elements of ultrasonic welding machine, from the definition, classification, working principle, applications, among other critical aspects.


1. Ultrasonic Tube Sealing Machine


 Ultrasonic Tube Sealing Machine

 Working Process-ultrasonic welding machine copper tube:


● The operator places the tube sealer over the charged fill tube and actuates the start switch.

● A pneumatic cylinder advances a cam to clamp the tube closed and ultrasonic vibrations at the 20 kHz frequency vibrate the inner tube wall surfaces to form a true metallurgical weld. 

● The tube is then cut off from the fill head completing the cycle in under 2 seconds.




Application- ultrasonic welding machine for copper tube:

● Refrigerator and air conditioner copper tube sealing. Vacuum parts of copper tube and aluminum tube sealing.


2. Ultrasonic metal spot welding machine

This kind of ultrasonic metal spot welder features high-quality ultrasonic transducer, strong power, good stability and it is widely used in metal products industry.The machine has built-in electronic protection circuit, which is safe to use.

3.  Ultrasonic wire welding machine

Ultrasonic welder wire splice is the future-oriented method for wire and terminal applications. Among other things the process is used for joining multiple wires with each other as well as for joining wires with grounding terminals or high-current contacts. Compared with crimping or resistance welding, this process offers numerous advantages. Besides the excellent electrical properties of the joint and the extremely low energy consumption, this method is particularly characterized by comprehensive process control and process data management.

The ultrasonic wire welder is a new industrial ultrasonic wire splice solution. It welds stranded, braided and magnet wires to create a wire splice, wire crimp or a battery cable splice. The connections it produces are used in the automotive, aircraft, computer and consumer electronics industries, as well as other process control and industrial instrument applications. It is most commonly used in the production of wire harnesses.

4. Ultrasonic Terminal Welding Machine



20KHZ 3000W Ultrasonic Terminal Welding Machine

All of these machines have the same working principle, they use ultrasonic frequency vibration principle to change ultrasonic vibration energy into friction energy and transfer to the metal surface to be welded ,while the friction produces heat under the pressure, the metal structure of molecules fully activation of the fusion between the molecular layer of the formation of the new equipment. Both of them are applicable to the following application areas:





● Auto splice welding, Formation of electric wire end, Welding for electric wires; Multiple electric wires bond welding.


● Electric wire and cable welding, terminal , connector , electric parts welding .


● Solar panel battery, flat solar plate , copper and aluminum plate joints.


● Solenoid switch, fuseless switch: big currency joint point welding and dissimilar metal welding.


● Refrigerator and air conditioner copper tube sealing. Vacuum parts of copper tube and aluminum tube sealing.


5. Ultrasonic plastic welding machine

As a joining process for industrial thermoplastics, the ultrasonic method of plastic welding machine ultrasonic is very well proven in practice. Particularly in the production of mass- produced parts, the process offers definite advantage over previous methods such as for instance high strength, clean weld seams, fast processing time, extremely low rejection rates and low energy consumption. 

In addition, this technique of plastic ultrasonic welding can be used successfully for riveting, forming, stacking as well as embedding of metal parts into thermoplastic materials.
