Plastic Welding

Plastics joining is inherently complex.

Ensuring strong, well-sealed joints without compromising component design is a constant challenge with new and evolving materials.

EWI develops customized solutions for plastic and composite welding applications, including joining dissimilar materials. From plastic welding consulting to evaluation, we do more than just show you how to join your parts. We help you identify which plastic welding process to use, optimize your design for that process, develop and validate your new process, guide your team through implementation, and support you through training and production launch.

Ideally, we start working with our clients at the beginning: part design and process development. Manufacturers that bring us in at a later stage often need us to analyze a failure or to redesign the tooling and process setup to fit a specific component. Our more unique plastic welding R&D capabilities include:

Experience and Integrity in Plastic Welding

Every weld we recommend is informed by specific application and deep industrial expertise. Whether it is about ensuring a plastic medical device is strong enough to save a life, or making a consumer product that is both elegant and reliable, we go all in to meet those goals and to unlock new possibilities for your application.

EWI has more than a 25-year history of plastic welding expertise and innovation across all manufacturing sectors. We’ve been an instrumental part of some breakthroughs over the years:

• Developed a method to powerfully bond a polymer film to a thin metal sheet without the use of adhesives.
• Conducted critical R&D on the effect of joint design on ultrasonic welding of polybutylene terephthalate (PBT), which proved that a less-expensive, longer-lasting energy director could be used with servo motion control during ultrasonic welding.
• Patented ultrasonic technology, UltraThinSeal™, for high-speed package film sealing that can be easily integrated into most standard thermal sealing bagmakers.
