Polymers

Developing strong, reliable bonds between polymers and metals has traditionally required adhesives or mechanical fasteners, adding weight, complexity, and limiting design flexibility. These conventional methods can also hinder product repair and recycling. But what if you could create durable, adhesive-free joints using only heat and engineered surface features? In a new paper, Enhanced Polymer-to-metal Joining,...

Developing reliable ultrasonic welding parameters for polymer joining traditionally involves a time-consuming and costly trial-and-error process. For many companies, this leads to wasted materials, labor, and resources, particularly when validating welds through expensive fatigue testing. But what if you could predict welding parameters using standard material properties, before any physical testing even begins?  In Prediction...

Advancing Polymer Weld Analysis to Prevent Fatigue Failures  At EWI, we always strive to solve the most pressing manufacturing challenges. We’re excited to announce the launch of a groundbreaking research initiative that focuses on a critical issue in polymer welding — identifying the relationship between intermolecular diffusion and fatigue failures using Heated After Cross-Section (HACS)...
