FAQ
Compared with other welding methods, ultrasonic welding can accept thermoplastic materials. It has many advantages, including process reliability and repeatability, lower energy use than other bonding technologies, saving materials and corresponding labor costs. What are the common problems in ultrasonic welding? What are the specific aspects?

Ultrasonic problem : abnormal heating of ultrasonic mold

When the ultrasonic mold is working, there will be a certain heating phenomenon, which is caused by the mechanical energy loss of the material itself and the heat conduction of ultrasonic objects. Whether the heating of ultrasonic mold is normal or not is judged as: when the ultrasonic mold is not loaded (i.e. not contacting the workpiece), the ultrasonic wave is continuously emitted for more than half an hour, and the temperature should not exceed 50-70 ºC. If the heat is damaged, it is proved that the ultrasonic mold has been damaged or the material is unqualified and needs to be replaced; if the mold temperature is too high, it is usually accompanied by abnormal high ultrasonic current;
