  HOW DOES THE ULTRASONIC CUTTER WORK?   Sound is a vibration that is transmitted through a medium, such as air, water, and metals.   Ultrasonic waves are an "inaudible sound," the frequency of which generally exceeds 20 kHz. A 20-kHz frequency means that a certain medium vibrates 20,000 times per second.   The ultrasonic cutter vibrates its blade with an amplitude of 10 -...

Robust Joint Design for Ultrasonic Welding of Plastic Parts While the concept of ultrasonic welding is simple, the process of designing a robust joint and developing an effective weld process can be quite complex. Typically, it starts with a nominal joint design, a nest and horn design, and the energy coupler gain to obtain the nominal vibration amplitude at the welded surfaces. Then, the process ...
