Your Benefits – Ultrasonic Welding Technology by Herrmann
Our ultrasonic components such as generators, converters, and sonotrodes are developed for continuous high-load operation in demanding automotive environments. Their robust design ensures long service life, minimal downtime, and consistent welding quality. This reliability reduces maintenance costs and keeps your production lines running efficiently, even at high volumes.
Automotive manufacturing demands speed and cost control. Ultrasonic welding meets both requirements by eliminating consumables such as adhesives and fasteners, cutting recurring material costs and simplifying logistics. With welding times of a few hundred milliseconds, the process shortens cycle times permanently – no curing, no cooling phases needed. This enables higher production throughput and reduces overall operating costs.
Combined with low energy consumption and minimal maintenance, ultrasonic welding delivers long-term savings and a cleaner, more reliable process compared to conventional joining methods.
Ultrasonic welding combines resource efficiency with high productivity.
By eliminating adhesives and other consumables, the amount of resources used and, consequently, operating costs are permanently reduced. The process requires significantly less energy than thermal joining methods, lowering operating costs and supporting sustainability goals.
Ultrasonic welding only needs fractions 100 to 300 ms to create hermetic connections, enabling faster production cycles. In combination with a reproducible, precisely controllable process, this delivers higher output with consistently high quality.
Ultrasonic technology is not limited to welding – it covers a wide range of processes for automotive applications. From precise ultrasonic welding of thermoplastics to ultrasonic staking, embossing, sealing and membrane embedding, ultrasonic systems offer unmatched flexibility.
This versatility enables manufacturers to handle complex designs and diverse materials with one technology.
Applications that benefit from this flexibility:
- Sensor housings for ADAS or LiDAR systems
- Interior components like door trims using staking
- Exterior parts such as bumpers with PDC slots created by ultrasonic punching
- Functional components like filter housings requiring hermetic sealing
- Acoustic elements through ultrasonic sealing for membranes
