Plastics Joining (Page 3)

Optically transparent medical testing devices, such as microfluidic chips and diagnostic components, require precise and delicate welding techniques to maintain their functionality and integrity. The need for clarity and the intolerance of contaminates make most welding approaches unsuitable.  Hot plate welding is too imprecise due to the need to move the parts during the joining...

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...
