Hermann Ultrasonic is a leading company in ultrasonic welding technology, providing consulting services and application engineering to solve problems related to plastic welding. Ultrasonic welding has a short cycle time and high reproducibility, making it suitable for mass production in various industries such as automotive, medical, and electronics. The technology uses high-frequency vibrations to generate heat and melt plastic materials, allowing for strong and reliable bonds. The process involves the use of a stack, consisting of a transducer, booster, and horn, to transmit vibrations to the plastic materials. The choice of plastic material is crucial, with non-crystalline materials such as PC and ABS being ideal for ultrasonic welding due to their ability to efficiently transmit vibration energy. Crystalline materials, on the other hand, require more energy and have a higher risk of degradation during the welding process.
