Understanding And Caring For The Heart Of Your Ultrasonic System

From Dukane Intelligent Assembly Solutions
 

 
Plastic welding is the most common application of ultrasonic assembly. To perform ultrasonic plastic welding, a vibrating tip is brought into contact with one of the work pieces as shown in Figure 1-1. Pressure is applied and ultrasonic energy travels through the material, increasing the kinetic energy (or heat) at the contact point of the two parts. The heat melts a molded ridge of plastic on one of the pieces and the molten material flows between the two surfaces. When the vibration stops, the material solidifies forming a permanent bond. A basic ultrasonic probe consists of - 1. A housing which contains the transducer which converts electrical energy into mechanical vibrations. 2. A horn to transfer the mechanical vibrations from the transducer to the parts to be welded. A basic ultrasonic probe is show in figure 1-2. As indicated, the horn is secured to the transducer with a threaded stud.
