Frequency matching is also very important

Friday, January 22, 2021

Frequency matching is also very important. This is firstly because the ultrasonic transducer can only work at its resonance frequency, so the drive power supply, horn, and mold (tool head) should all work at this frequency. Generally speaking, this difference […]
