How to do if the erection of ultrasonic mould is not accurate and the stress is not even?

In general, it is believed that when the ultrasonic operation, as long as the contact between the product and the mold surface is accurate, the welding effect can be obtained. In fact, this is only the view of the surface. Since the ultrasonic is a friction vibration, it will produce the phenomenon of acoustic transmission

If we only observe the stability of the hardware (mold) and ignore the integrated mode of ultrasonic operation, it will inevitably lead to the consequences of abandoning the essentials or misjudgment. Therefore, the ultrasonic engineer of youwo must first emphasize that the operation mode of ultrasonic welding is to conduct acoustic waves, so that the vibration friction is converted into heat energy for welding The section, thickness, depth and texture of the product must not bear the same pressure.

On the other hand, each point of the energy output by horn has its error value, not the energy output by the whole plane is the same. On the whole, there is bound to be a difference in the degree of product welding. Therefore, it is necessary to make a correction. How to correct it is to rely on the horizontal screw of the ultrasonic welding machine itself, or to stick a thin tape or aluminum foil.
