The 70 khz ultrasonic transducer is applied to embedding the coil wires to the smart card, or RFID card, and other small samples welding applications.This small welding horn to weld, embed, or inlay, many kinds of small parts with different type shapes.


The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.Ultrasonic smart card welding equipment transmitted ultrasonic energy through welding parts to welding area, local high temperature will happen due to high acoustic resistance between two welding interface places. Also, no enough time dissipating out heating energy timely because of poor plastic thermal conductivity, heating energy gathered in welding area since could not dissipating out timely, the two plastic contact areas will welt rapidly, coupled with a certain pressure, it makes fusion to one unite. When ultrasonic stop function, and keep the pressure sustain to make its solidification molding, finally forming a strong molecular chain, which achieve the purpose of welding. And the welding strength can close to raw material body strength.




1. steady welding point, completely eradicate insufficient solder technically.

2. the size of welding spots is the same, equality line, good effect on uniformity

3. the welding spot is small, wouldn’t increase the weight of the coil, easy to do lamination and encapsulation

4. to leave out the immersion tin step before doing welding ,save an operator.

5. after skilled in welding, much faster than the way to use searing iron to do weld.

6. on the process on manufacturer, there is no waste gas, waste rubbish on pollution, runs in quiet and no noise.

7. to select the the frequency 60KHz, one machine could drive 5-10 ultrasonic products, the speed to do welding is much faster.

8. low power consumption, to save production cost for manufacturer enterprise.
