Ultrasonic welding transducers generate high-frequency vibrations of tens of thousands of times per second through the transducer at the vibrating head, generating local high temperatures, and melting the plastics in the weld zone for welding purposes. The ultrasonic welding transducer generally adopts a bolt-clamped longitudinal array structure, which is connected with the fixing fixture and the gathering head to form a plastic welding vibration system.

1. The resonance impedance is low.
2. The mechanical Q value is high.
3. Electroacoustic conversion efficiency is high.
4. Low calorific value.
5. Large amplitude and high vibration speed.
 

1. Select the appropriate material and set the hardness process to process the horn and the working head.
2. When installing the horn or the working head, be sure to pay attention to the frequency matching, and apply the sound-adhesive glue at the joint seam.
3. Clean the surface to be joined with a solvent such as acetone during installation.
4. Establish the impedance control process of the bonding process to reduce the impedance of the vibrator and improve the electro-acoustic conversion efficiency of the vibrator.
5. Pay attention to improve the insulation measures after the vibrator electrode is installed.
