Ultrasonic refers to elastic vibration waves (sound waves) with frequencies so high that they do not produce a sensation of hearing in people with normal hearing. The range of sounds that humans can hear is approximately from 20 Hertz at the low end to about 20,000 Hertz at the high end (there are individual differences). In this blog, we provide essential knowledge about "ultrasonics," which is indispensable for ultrasonic welding. We also introduce the applications of ultrasonics in detail, dividing them into "communicative uses" and "power uses." Please take a moment to read.

In ultrasonic plastic welding, a joint design called an energy director is necessary to efficiently transmit vibration energy. The energy director needs to be designed for each welding case and is one of the important elements in ultrasonic welding. In this blog, we cover topics such as "What is Joint Design? Key Points in Ultrasonic Welding," "Guidelines for Joint Design," and "Representative Examples of Energy Directors." Please take a moment to read through it. [Content Included] ■ What is Joint Design? Key Points in Ultrasonic Welding ■ Guidelines for Joint Design ■ Representative Examples of Energy Directors - Butt Joint - Shear Joint *For more detailed information, please refer to the related links.
