Ultrasonic Disc: Ultrasonic welding technology for automated plug assembly

ITW Global Fasteners presents the Ultrasonic Disc, a hole-sealing solution developed for automated, high-speed assembly processes. Combining ultrasonic welding with a dedicated disc design, it enables reliable hole closure in less than one second while achieving high pull-out forces. Its ultra-flat profile (<2 mm) allows installation in space-constrained applications without requiring B-side installation space. The welding process creates a reliable seal that protects against water, moisture, and other environmental influences. High tolerance to contaminants such as wax, oil, hand cream, and fingerprints ensures robust performance and process flexibility across multiple vehicle production stages.
