Combining video with data acquisition programs can deliver a highly sophisticated tool for diagnosing potential problems and making adjustments while fabrication is in process. There are existing high-speed camera (HSC) and data acquisition (DAQ) systems that have been custom-built, but to-date these have been cumbersome to operate and commercially unsupported. EWI has developed a new,...

Four EWI associates have co-authored chapters in POWER ULTRASONICS: APPLICATIONS OF HIGH-INTENSITY ULTRASOUND, 2nd Edition, edited by Juan Gallego-Juarez, Karl Graff, and Margaret Lucas: Lindsey Lindamood and Mitch Matheny contributed to Chapter 10, "Ultrasonic Welding of Metals."Miranda Marcus was a co-author on Chapter 11, "Ultrasonic Welding of Plastics and Polymeric Composites."Amin Moghaddas co-wrote Chapter 15,...

For certain manufacturing applications, making selected components out of plastic via 3D printing has great advantages. A significant disadvantage for high-volume production, however, is the slow extrusion rates of polymer materials. EWI has developed a new technique using ultrasonic power that can increase the speed of polymer extrusion. This method is discussed in Speeding Up...
