800W Ultrasonic Pizo Electric Transducer with 38MM Diameters Ceramics
Description:
Ultrasound can be divided into three types, namely, infrasound, sound waves, and ultrasound. The frequency of the infrasound wave is below 20 Hz; the frequency of the acoustic wave is 20 Hz to 20 kHz; and the frequency of the ultrasonic wave is above 20 kHz. The secondary sound waves and ultrasonic waves are generally inaudible to the human ear. Due to the high frequency and short wavelength, the ultrasonic wave has good directionality and strong penetrating power, which is why the ultrasonic cleaning machine is designed and manufactured.

Ultrasonic plastic welding method:
1. Welding method: Ultrasonic vibration transmits ultrasonic waves to the weldment along with the welding head. Due to the large acoustic resistance of the two weldments, local high temperature is generated, and the weldment interface is melted. Under a certain pressure, the two weldments achieve a beautiful, fast and strong welding effect.
2, implant (insert) method: nut or other metal to insert into the plastic workpiece. First, the ultrasonic wave is transmitted to the metal, and after high-speed vibration, the metal object is directly buried in the molded plastic, and the plastic is melted, and the solidified material is buried.
3, riveting method: To join metal and plastic or two plastics with different properties, ultrasonic riveting method can be used to make the welding parts not easy to be brittle, beautiful and strong.
4, spot welding method: the use of a small welding head to two points of large plastic products welded, or a whole row of toothed welding head directly pressed on two plastic parts, in order to achieve the effect of spot welding.
5. Molding method: The plastic workpiece is instantly melted and formed by ultrasonic waves, and the plastic of metal or other materials can be solidified when the plastic is solidified.
6. Resection method: The special design method of the welding head and the base is used. When the plastic workpiece is just shot out, it is directly pressed on the branches of the plastic, and the effect of the resection is achieved by ultrasonic conduction.
