Judgment of the quality of the ultrasonic welding press

Requesting Main Industry : Manufacture of automotive resin parts

Request for measuring the load and vibration at the same time with an ultrasonic welding machine

Problems we had

Incorrect timing of oscillation and load during ultrasonic welding may lead to incorrect bonding of the resin. The vibration linked with the load could not be seen even if the start time of oscillation could be seen by the acceleration sensor.

Solving Problems

Ultrasonic welding press

Because piezoelectric load sensors have very high responsiveness, load signals and oscillation timing can be monitored simultaneously. It is possible to monitor the load at an appropriate oscillation timing to catch the waveform change when a failure occurs and prevent the outflow of defective products.
