What is ultrasonic tinning?Ultrasonic tinning is a kind of welding method that does not use flux. The ultrasonic probe produces cavitation in the molten solder core through mechanical vibration at ultrasonic frequency, and removes the oxide film on the metal surface for smooth and clean tinning.

1. Ultrasonic Plastic Welding Machine When ultrasonic acts on the thermoplastic plastic interface, it produces tens of thousands of high-frequency vibration per second. This kind of high-frequency vibration reaches a certain amplitude. The ultrasonic energy is transmitted to the welding area through the upper welding parts. Because the acoustic resistance of the welding area, i.e. the interface between two welding parts, is high, local high temperature will be generated.

Ultrasonic metal welding is a special method of connecting the same metal or different metal by using mechanical vibration energy of ultrasonic frequency. When metal is welded by ultrasonic wave, it neither conveys electric current to the workpiece nor applies high temperature heat source to the workpiece, but transforms mechanical energy into internal energy, deformation energy and heat under static pressure.

What is an ultrasonic horn (horn)We know that when an object vibrates, it makes a sound. Scientists refer to the number of vibrations per second as the frequency of the sound, and its unit is Hertz. The frequency of sound waves that we can hear in human ears is 20 to 20,000 Hz. When the vibration fr
