Polymers

Plastic Welding Essentials is a one-hour technical webinar led by Dr. Miranda Marcus, Senior Engineer and EWI’s technical lead for plastic and composite welding. Drawing on over 15 years of experience in polymer welding and joining, Dr. Marcus presents key principles engineers, product managers, and other decision makers should understand in a clear, practical, and...

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...
