HOW CAN WE HELP?

EIS is a fabricator and converter of flexible materials and adhesives, providing Engineered Solutions and Distribution Solutions. Our engineers provide design, rapid prototyping, and custom converting capabilities to assist with your fabrication needs.

Ultrasonic welding uses high frequency, low amplitude vibration to create heat between the two materials being joined. Both materials must be made from similar amorphous polymers and have near equivalent melting points when used with plastics. The thermal rise in the bonded area is produced by the absorption of vibrations and friction of the part's surface. The material plasticizes locally, creating an insoluble connection between both parts within a brief period of time.

The joint quality is uniform because the energy transfer and the released heat remain constant and limited to the joining area. Ultrasonic welding is fast and clean and is well-suited for small parts. For example, ultrasonic welding can be used to create an anti-microbial cover using non-woven fabric material.
