Plastics Joining (Page 4)

Auto manufacturers and suppliers need a valid, reliable way to detect flaws in electric vehicle battery enclosures, or modules. EWI has developed an inexpensive testing method with demonstrated feasibility! Our team validated an EV battery testing procedure involving colorimetric chemical reagents and a reactive gas. It’s a high-resolution marking method that’s faster and clearer than...

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...

By James Cruz, EWI An example of a PVC-aluminum laser weld. Just try to break this! My first job out of college at Honda of America Manufacturing was a dream come true—the chance to play with robots and build cars! They handed me several crisp, white uniforms on day 1. Within that first week on the production...
