WebWelding times can vary, but the welds can form in as little as 0.25 seconds. The factors that vary in ultrasonic welding are the frequency of the sound waves (usually 20, 30 or 40 kHz), the pressure applied to hold the materials together, and the time over which the ultrasound is applied (fractions of a second to more than one second). WebMay 31, 2024 · One example of a common but potentially troublesome change involves moving from an easy-to-weld amorphous material such as ABS, to a much more difficult-to-weld semi-crystalline polymer, such as PP. ABS requires lower ultrasonic stack output (30-70 microns at 20 kHz) for successful welding than does PP (90-120 microns). WebUltrasonic plastic welding is a fast and efficient technique that creates a strong, clean and hermetic seal, while increasing production without compromising quality.
