There are several different ultrasonic frequencies that can be used for plastic welding. The frequency is usually determined by the specific application. The three biggest factors that are involved in selecting frequency are:
- Part Geometry
- Part Size
Ultrasonic welding systems are available in a range of frequencies, typically ranging from 15 kHz to 40 kHz. The most common frequencies used in ultrasonic welding are 20 kHz and 40 kHz.
Lower frequencies, such as 15 kHz, are typically used for welding thicker materials, such as metals or large plastic parts, as they provide more energy and better penetration. Higher frequencies, such as 40 kHz, are typically used for welding thinner or more delicate materials, such as medical devices or electronics, as they provide greater precision and control.
The choice of frequency for a particular welding application will depend on several factors, including the thickness and type of materials being welded, the size and geometry of the parts, and the desired weld quality and strength.
