1. What is an Ultrasonic Sewing Machine?
An ultrasonic sewing machine utilizes ultrasonic welding technology to bond layers of plastic materials, non-woven fabrics, or thin films, completely without needles or threads unlike traditional sewing methods. This technology works by generating high-frequency vibrations to create localized heat, welding the material layers together.
