Ultrasonic lace machine in the use of bad welding how to do?

Poor welding may be caused by the following reasons:

Material mismatch: Ensure that the ultrasonic lace machine is suitable for the material being processed. 

Improper power adjustment: Adjust the power output to ensure that the energy is suitable for material fusion. 

Mold wear: Check if the mold is worn and replace it with a new one if necessary. 

Material moisture: Ensure that the material is dry, as moisture can affect the welding effect. 

Equipment calibration: Check if the equipment needs calibration to ensure the accuracy of energy output.
