Abstract

See full text

In one embodiment of the present invention, a method of affixing a screen sub-assembly to a substrate includes the steps of depositing a thermoplastic material on a surface of the substrate and placing the screen sub-assembly on top of the substrate. The screen sub-assembly includes a screen element and a thermoplastic material. The method also includes the steps of placing the screen sub-assembly and the substrate on a movable surface and driving the movable surface across a base support surface so as to position the screen sub-assembly and the substrate below an ultrasonic welding device. The ultrasonic welding device is actuated to emit ultrasonic energy that results in the screen sub-assembly being affixed to the substrate. The substrate can be formed of a perforated metal plate and a coating of thermoplastic powder.
