In modern busbar manufacturing, the connection of copper and aluminum has long been standard. However, the implementation is technically demanding and in many manufacturing processes leads to rejects and unreliable connections that lose quality over time. Ultrasonic welding offers a particularly process-stable, material-friendly and economical alternative that has proven itself in numerous industrial applications.
In busbar manufacturing, developers are faced with a central challenge: creating connections that are both highly electrically conductive and extremely resilient mechanically — permanently, reproducibly and in short cycle times. Ultrasonic welding can solve this challenges.
Efficient joining technologies play a central role in the modern manufacturing of busbars. Especially in the manufacture of busbars, which are used in power distribution systems, electric vehicles and other high-current-carrying applications, choosing the right joining technology is crucial for product quality, production efficiency and cost structure.
The benefits of ultrasonic welding for membranes used in filtration and venting
Ultrasonic welding has established itself as a proven process for integrating membranes into applications with pressure equalisation or filtration functions. Shorter process times and clean, reproducible results make this joining technology particularly attractive for automated production systems where the focus is on increasing output and efficiency.
How ultrasonic bonding makes hygiene products more eco-friendly
Legal requirements and changing consumer behavior make sustainable production methods in diaper manufacturing a necessity. At the same time, companies are under pressure to optimize their costs and remain competitive. Ultrasonic welding offers an innovative solution that combines ecological and economic advantages.
Manufacturing adhesive-free hygiene products with ultrasonics
Manufacturers of hygiene products such as diapers are constantly under pressure to reduce costs while delivering high-quality products. One effective long-term method of meeting these requirements is to use ultrasonic bonding instead of conventional adhesives. This efficient joining method offers significant advantages in terms of cost savings, efficiency, and sustainability.
How ultrasonics optimizes the manufacturing of hygiene products
Diapers are an indispensable companion for babies or adults with incontinence problems. In addition to key aspects such as absorbency and leak protection, wear comfort is becoming increasingly important when selecting the right diaper. Consumers are paying more and more attention to products that feel soft on the skin and are comfortable to wear.
The softness of nonwoven materials plays a decisive role here. But how can the softness of the nonwoven material be preserved during the manufacturing of diapers and other hygiene products? Choosing the right bonding process is a key factor.
Ultrasonic welding has established itself as an efficient and precise joining technology in the manufacturing of plastic heat exchangers. It enables the tight, stable and material-friendly connection of components without the use of additional joining agents such as adhesives or screws. This process plays a particularly important role in applications involving aggressive mediums or high demands on tightness.
Herrmann is thrilled to announce the grand opening of its newest Tech Center and laboratory in Monterrey, Mexico, on April 24, 2025.

Automated connection of medical components for maximum output
Perfect for automated assembly: Thanks to minimized welding times and real-time process control, ultrasonics is ideal for manufacturing medical components in high volumes. Find out the advantages of the technology for your application in this article.
Joining Plastics of Medical Devices Without Adhesive
Particularly for medical products with direct skin contact, high wear comfort and skin compatibility are crucial for the quality of the product and customer satisfaction. Manufacturers should therefore avoid chemicals such as IBOA and connect plastics with processes that do not require adhesives, solvents or environmentally harmful substances - ultrasonics make this possible.
The switch from PVC to thermoplastic elastomers (TPE) in medical technology promotes health and environmental protection. TPE is phthalate-free, biocompatible and easier to recycle, which reduces the risks of allergies and environmental pollution. Despite challenges in joining TPE, ultrasonic welding offers an effective solution for stable and durable joints. This step improves product quality and minimizes health risks in the medical industry.
Minimal scrap rates with twice as fast cycle times: New developments in ultrasonic welding enable an optimization of production and can permanently reduce manufacturing costs for batteries and wire harnesses. A big help comes from the experience gained in the welding of plastics.
Increasing the sustainability of EV with ultrasonics
