The amplitude is the movement on the horn surface. The amplitude is depending on the output power of the power supply, Generator setting, Gain of the Booster and Gain of the horn. The amplitude is chosen depending on the material to weld.
The amplitude is measured in micro meter. The value is peak. Typical amplitude values are 10 – 60 micro meter.
This picuture show the compatibility of common plastic materials. Some amorphous materials, especially Styrene is allowed to be welded to different materials. For semi-crystalline, only the same materials can be welded together.
