How to deal with the damage of internal parts after ultrasonic welding?
1. Advance ultrasonic vibration time (avoid contact vibration).
2. Reduce the pressure, reduce the ultrasonic welding time (reduce the strength standard).
3. Reduce the number of power segments or small power machines.
4. Reduce the expansion ratio of ultrasonic mold.
5. Cushion rubber shall be padded at the stressed part of bottom formwork.
6. Avoid hanging or gap between bottom mold and products.
7. The frequency of horn (upper die) is measured again after cutting.
8. Apply elastic material (such as silikang) after the upper die is cut.
