The Application Principle Of Ultrasound in Plastic Processing

The ultrasound used in plastic processing has several working frequencies, including 15KHZ, 18KHZ, 20KHZ, and 40KHZ. The principle is to use the peak position of the longitudinal wave to transmit the amplitude to the gap of the plastic part. Under pressure, the molecules in the contact area between two plastic parts or other parts and the plastic part collide and melt, causing the plastic in the contact area to fuse and achieve the processing purpose. In the case of strength, it should be removed as much as possible. In some cases, it is necessary to clean the plastic parts first.
