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.
Herrmann Ultrasonics is thrilled to announce the grand opening of its newest Tech Center and laboratory in Monterrey, Mexico, on April 24, 2025. With over 60 years of pioneering German-designed ultrasonic technologies, this milestone marks a significant step in bringing the latest innovations closer to manufacturers and industry leaders in Mexico and beyond.

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.
Joining medical applications quickly and sustainably with ultrasonics
Connecting plastics without adhesives: Using ultrasonics as a joining technology, companies can produce their applications skin-friendly and eco-friendly. If certain specifications for the components are met, the process can also be used for sensitive applications with complex geometries.
At Herrmann Ultrasonics, we believe that feedback is a gift. As part of our ongoing efforts to improve customer experience, we've introduced a new Customer Satisfaction Survey.
New process: Sealing uncoated paper with ultrasonics
Ultrasonic sealing of uncoated paper is a joining process that is as innovative as it is environmentally friendly, enabling packaging companies to save significant amounts of energy and resources.

A collaboration that generated a lot of excitement on both sides.
Sustainable and efficient sealing with the new TSM
Save energy and material permanently: with the TSM Top Seal Module Herrmann Ultraschall offers a simple solution for sealing packaging materials more efficiently and reliably. Thanks to the new solution for sealing the hermetic and cosmetic seal at the same time, companies can also reduce the size of their packaging machines.
Ultrasonic sealing and heat sealing are the two most common methods used for sealing in packaging and manufacturing today. What are these processes, and why do facilities choose one over the other? We will examine ultrasonic sealing vs. heat sealing in greater depth throughout this piece, first defining each one:
Flawless appearance was the major challenge in welding an oval, three-dimensional half case for a consumer product. A joint development process between BSH and Herrmann Ultraschall succeeded in meeting these requirements while also providing strong joints.

For the producers, manually inserting 18 brass female connectors into a plastic frame for a control unit was a laborious and costly process. Ultrasonic welding offered an efficient alternative which considerably shortened the cycle times and was also financially worthwhile – in spite of a lower unit count. The versatility of the sonotrode and HERRMANN ENGINEERING played a crucial role here.
The insertion of elastic threads can be complex and costly in the manufacture of hygiene products. Herrmann Ultraschalltechnik GmbH & Co.KG, Karlsbad, Germany, has developed a novel patented method for fixing elastic threads that simplifies handling, reduces the risk of breakage, enlarges the process window and lowers production costs.
Booming electromobility and the growing demand for fast charging technologies result in increasing system voltages for electric vehicles. This requires powerful cable harnesses and power rails, which in turn requires larger cable cross sections and/or metal sheet thicknesses. The higher the cross section, the more difficult the welding. For this purpose, Herrmann developed the Ultrasonic Power Stack 12000+ as an extension for their HiS VARIO W ultrasonic welding machines.
Battery management systems (BMS) for cylindrical cells require precisely adjustable low weld forces. Herrmann has developed a new module which suits especially the welding of BMS to small cylindrical cells and finest materials, that can easily be integrated in existing production processes.
Welding of materials within milliseconds, according to type
Plastic products and packaging will still play a major role in future. However, the aim is to use and reuse this valuable material as long as possible. Sustainable processing by ultrasonic welding helps reach this aim.

As of now there are few inquiries for the welding of recycled materials, ie plastics that already have been processed once or more before. The weldability must be determined empirically in the test laboratory.
Ultrasonic technology can also deliver good sealing results with narrow process limits, especially with regard to tightness and visual appearance. The thermal expansion is kept to a minimum. Thermal processes demonstrate disadvantages of excessive heat input, especially in the continuous welding of film webs.
Ultrasonics for cuff elastic is a relatively new topic. How were they processed before?
