It may be that the frequency is not reached when the frequency trimming is not fine enough, so the ultrasonic energy is not completely released during use, but most of it stays in the ultrasonic mold.
Over time, the mold will have weak welding during use, the mold will heat up, and then the mold will have cracks. To solve this problem, you must first choose the ultrasonic mold made by a professional ultrasonic welding machine manufacturer to make the mold reach the state.
The power loss of the ultrasonic sensor itself, because the energy conversion efficiency cannot reach 100%, the energy loss needs to be converted into heat. An increase in temperature will cause changes in sensor parameters and gradually change the matching state.
What’s more serious is that the temperature increase will cause the deterioration of the piezoelectric ceramic sheet performance. This in turn causes the sensor to work worse and heat up faster, which is a vicious circle.
The user failed to match the sensor with the driving power to the working state when using the sensor. The heat generated by this is too great to be controlled and the consequences are serious. The heating of any part of the vibration system will affect the working state of the entire system. In severe cases, the ultrasonic sensor, ultrasonic mold or ultrasonic generator will be damaged.
