The Process of Vibration Welding
by Jordan Rotheiser, Rotheiser Design Inc. In my day, Boy Scout manuals described a method for creating a fire by rubbing two pieces of dry wood together. However, this particular Boy Scout was never successful at creating anything more than a sore arm with this technique. I now realize that the problem was that I never achieved speeds of 120 cycles per second in rubbing the … [Read more...] about The Process of Vibration Welding
Molded Part Considerations: Troubleshooting the Ultrasonic Welding Process
by Kenneth A. Holt, Herrmann Ultrasonics, Inc. Although injection molding and ultrasonic welding are both well known and documented processes, the interplay of the two oftentimes is not understood. Hopefully, by discussing problems and solutions in this interplay, this article may aid those who produce assemblies that are ultrasonically welded. Ultrasonic welding is a … [Read more...] about Molded Part Considerations: Troubleshooting the Ultrasonic Welding Process
