Ultrasonic Welding

MMT&P offer Ultrasonic welding service, a post-processing technique designed to join parts together using a solid-state weld. Ultrasonic welding is useful when bonding two plastics together or when working with other dissimilar objects that have trouble bonding. During the ultrasonic welding process, the two components are held together in a fixture under pressure. Then, high-frequency ultrasonic acoustic vibrations are played through a vibrating tool called a horn. The frictional heat generated from the vibrations melts the substrate, creating a localized weld area that joins the two parts together.

Ultrasonic welding doesn’t require any fasteners like bolts or nails, soldering materials, or adhesives. Like heat stakes inserts, ultrasonic welding reduces set-up time and costs and reduces opportunities for corrosion, fastener stripping, or other long-term issues. Ultrasonic welding is a fast and efficient finishing process that is easily repeatable, requires little clean-up, and takes mere seconds to complete.
