FAQ – The Most Important Questions and Answers about Welding with Ultrasonics
With ultrasonics, thermoplastic materials can be connected quickly, safely and firmly. You can find an overview of common plastics that can be welded with ultrasonics here.
With over 60 years of experience, we are also happy to consult you on the selection of the right plastic for your medical application.
Ultrasonic welding joins plastics by using high-frequency vibrations to create localized frictional heat at the interface of two parts, causing the plastic to melt and bond. The parts are held under pressure while the vibrations generate heat, and once the plastic cools, a strong, permanent joint forms without the need for adhesives or fasteners.
This process is fast, precise, and clean, making it ideal for the manufacturing of medical devices. Especially products that are worn directly on the body, such as in the areas of diabetes or ostomy care, benefit from connections without chemicals.

In our white paper “The most important success factors for component design”, which geometries and materials we can weld with ultrasonics and how your application can benefit from ultrasonics to the maximum.
Ultrasonics is used to connect plastics without additional joining agents and therefore also without chemicals. This is particularly beneficial for wearable medical devices. Because without adhesives, which often contain isobornyl acrylates (IBOA), skin compatibility and wearing comfort are greatly improved.
Hospital care applications benefit above all from hermetic, strong and reliable connections.
Thanks to the gentle joining process, even complex geometries of small, delicate components can be safely connected. The fast process is also ideal for the automated production of applications in large quantities, increasing the output of the production and reducing the costs.
In addition, ultrasonics can also create a strong and safe connection with thermoplastic materials. This makes it possible to switch to more eco-friendly, recycled plastics.

Ultrasonic welding is a widely used and reliable manufacturing process, known for its safety, precision, and speed.
We achieve this by individually defining the right welding parameters for each application in our ultrasonic laboratory. These parameters are saved in the generator of your welding system and can be reliably reproduced for each individual welding process in your manufacturing.
The welding system's intelligent controller software ensures this exact reproduction. It monitors the process and measures up to 150 data records per weld. This not only makes the process safe, but also enables uncomplicated, digital quality control.
In ultrasonic welding, process capability (CpK) ensures that the welding process consistently produces parts within specification limits, while Overall Equipment Effectiveness (OEE) measures the machine's efficiency by evaluating availability, performance, and quality. A high CpK and OEE indicate that the ultrasonic welding process is optimized for minimal variation, high-quality welds, and maximum productivity.
