20Khz 50mm Ultrasonic Welding Transducer for Continue Work Fabric Sealing

What is ultrasonic transducer Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies and convert electrical signals into mechanical vibrations by the piezoelectric effect of the material. When the transducer is used as a transmitter, the electrical oscillating signal sent from the excitation source will cause a change in the electric or magnetic field in the electrical energy storage element of the transducer, which changes the mechanical vibration system of the transducer through some effect. A driving force is generated to cause it to vibrate, thereby propelling the medium in contact with the mechanical vibration system of the transducer to vibrate and radiate sound waves into the medium.

The ultrasonic welding transducer has the same starting principle as the cleaning transducer, but it has a higher power consumption. It usually cooperates with a plastic welding vibration system composed of a concentrating horn and a working head to complete ultrasonic welding of plastics, metals and the like. Ultrasonic welding transducer features: 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. Installation Precautions: 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.
