Portable ultrasonic car noise board spot welding machine welding principle The 900W ultrasonic plastic spot welding machine converts 28KHZ high-frequency electric energy into mechanical vibration energy by ultrasonic transducer, and then transmits it to the welding head through the variable ampli

When we using our transducers, there are some reflections of aluminum cracking of the transducer or horn from time to time. Moreover, in the failure of aluminum cracking of the transducer, there is another phenomenon that is worthy of attention. The failure of the aluminum cracking of the transducer

Ultrasonic plastic welding machine principleWhen ultrasonic waves act on the thermoplastic plastic contact surface, high-frequency vibrations of tens of thousands of times per second are generated. This high-frequency vibration reaches a certain amplitude, and the ultrasonic energy is transmitted to

Ultrasonic welding conditions:As the conditions for ultrasonic welding, the most important time is the time (vibration, welding time) and pressure at which the welding energy is applied. Of course, other conditions are also important.Welding temperatureThe viscous flow temperature of the ultrasonic

Common defects and Solution of ultrasonic weldingFirst, the strength can not reach the desired standard.Of course, we must understand that the strength of the ultrasonic welding operation can never reach the strength of integral molding. It can only be said that it is close to the strength of integr
