Herrmann Ultrasonics, Inc., Bartlett, IL, to host Automotive Technology Day Oct 12th with latest innovations on automotive bonding applications When it comes to joining automotive plastic parts, visual appearance, geometry, function and material properties have become increasingly demanding. Ultrasonic welding is an assembly method with short cycle times, ensuring a large degree of process control…
Herrmann Ultrasonics introduces two new features at MD&M WEST 2017
At MD&M WEST 2017, Herrmann Ultrasonics introduces two features to ensure more safety when changing welding tools within the production process. Firstly an RFID reader has been integrated into the tooling which guarantees that the right tool is installed for the production. Not only is it built into the sonotrode but also into the fixture.…
Sophisticated ultrasonic welder solves difficult problems
Herrmann Ultrasonics Inc. has worked with medical company Genicon to build one of the largest ultrasonic medical weld tools ever designed. The product being welded — a newly designed suction irrigation handle — which was shown by Genicon at the recent MEDICA 2015 tradeshow in Germany. More after the jump. The device in its entirety is used…

In 1990, Thomas Herrmann, the son of Walter Herrmann, who founded Herrmann Ultraschalltechnik GmbH in 1961, established Herrmann Ultrasonics Inc. in the Chicago area. Hermann Ultrasonics, Inc. is proud to recognize a milestone year in observance of their 25th anniversary. Herrmann Ultrasonics has been focused on providing ultrasonic welding technology for various markets such as…
Ultrasonic welding preserves abilities of medical test chips
Antibiotic-resistant infections represent a latent hazard for patients and a serious challenge for health care facilities. Greiner Bio-One, an international medical technology company, has created a test chip to help detect these infections. To create this chip, two pieces of polystyrene must be joined without disrupting the chips characteristics. The test chip, called Genspeed, is…
Microfluidic device manufacturing
Ultrasonic Welding. Welding with ultrasonic vibrations is a cost-effective and safe method for joining the two halves of a polystyrene microfluidic test chip in such a way that the function is assured. The cross-section in the test channel has to remain constant at all times in order to achieve the required capillary effect. An energy…
Functional integration in ultrasonic welding
Ultrasonic welding. In semi-automated multi-head machines, several processes are often jointly integrated to achieve high functional density in confined spaces. Parts assembly functions, component detection and sensing features, as well as various test processes are added to the actual joining process. The ultrasonic welding machine interconnects all auxiliary functions and creates interfaces. The conventional concept…
Ultrasonic welding joins dissimilar plastics for medical applications
Often in medical part production, different materials have to be joined, like amorphous polystyrol (PS) and semi-crystalline polyethylene terephthalate (PET), such as in a dental applicator for treating caries at an early stage. Ultrasonic welding produces a controlled melt for a tight bond with minimal thermal load. The key to success is the variable programming…
Ultrasonic welding: The Challenge of an Extended Windscreen
A French automotive supplier needed a cable duct to cover an FPC (Flexible Printed Circuit), which supplied the electrical functions of console lighting, rain sensor and headlamp dipping in a vehicle’s rearview mirror through the main wiring loom in the headliner. The cable duct, comprised of an upper and lower shell, was necessary because the…
