Ultrasonic joining of polymer mats to mechanical devices including electric appliances

摘要

A method is provided for securing a polymer blanket to a mechanical device. The method includes positioning the polymer blanket against a polymer surface of the mechanical device and ultrasonically joining the polymer blanket to that surface. The invention also relates to a mechanical device including a mechanical component and a polymer insulator ultrasonically joined to a polymer wall of the mechanical device and at least partially enclosing the mechanical component.
