Selecting the right material for a new medical device -- especially when it comes to polymers -- is critical to the success of the product. Material failures are costly and common; more than a third of FDA recalls are due to material problems. Preventing Material Failure in Plastic Products: A Resource for Medical Manufacturers, written...

Ultrasonic wire bonding (UWB), today’s preferred method for joining wires to battery packs in electric vehicles, requires very high surface cleanliness to assure successful bonds. Decontaminating battery terminals, however, can be a very difficult and time-consuming task. EWI has recently completed a study using laser cleaning technology on batteries prior to UWB of aluminum wire...

Manufacturing engineers need tools that can help them understand microstructural changes during processes like welding, additive manufacturing, and heat treatment. Some available techniques (analytical, empirical, FEA) have been discussed in EWI’s recent ICME series* of papers. An additional approach uses phenomenological modeling to provide information important to predicting metallurgical behavior. EWI associates Rafael Giorjão and...
