Ultrasonic Welding

Ultrasonic Welding is the process of joining two plastic work pieces or any other dissimilar materials by using high frequency acoustic vibrations. The work pieces are hold together under pressure. Reed Switches could be damaged by ultrasonic welding and trials are required to ensure that the harmonics of the housings and the enclosed reed switch do not interact.

Ultrasonic welding is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics, and especially for joining dissimilar materials. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together.
