What Amplitude is needed to weld my plastic components?

What exactly is “Amplitude” and why is it important?  Amplitude is the peak-to-peak movement, or expansion/contraction, of an ultrasonic tool stack.  Each component can multiply the amplitude that comes from the transducer, the amount of increase or decrease is called “Gain”.  The total gain of the stack components determines the final amplitude at the working… Continue Reading What Amplitude is needed to weld my plastic components?

How does your Ultrasonic Probe/Stack work?

Ultrasonic Probe 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… Continue Reading How does your Ultrasonic Probe/Stack work?
