Ultrasonic welding process is very helpful to the production of enterprises, but in case of improper use or poor selection of accessories, ultrasonic welding will also cause surface burns. What are the causes of ultrasonic welding surface burns?
1. Poor workmanship of ultrasonic die and uneven stress cause local energy concentration.
2. The output energy of ultrasonic welding machine is too high
3. The selected magnification ratio is incorrect.

For such welding damage, it is necessary to first analyze the specific problem to see what causes it, and then make corresponding solutions for different problems. For example, for the above reasons, it can be solved as follows: a: Try to avoid the welding damage of the ultrasonic mold; b: Adjust the output capacity of ultrasonic welding machine; c: Select the correct magnification. When the ultrasonic welding surface is easy to burn, if you can't confirm what is going on, you'd better consult the relevant professionals!
