Ultrasonic welding is well suited for a large number of automotive components, where high part counts and appropriate strength are required. These include many parts made of thermoplastic materials for interior and exterior applications, and engine compartments, but also of nonferrous metals for cable harnesses and lithium-ion batteries:
More on the industry
Food is better protected by good packaging and kept fresh longer which is more sustainable. Ultrasonic sealing technology has become an established and economic alternative of heat sealing:
Laminating without the use of adhesives and embossing without the use of heat? The absolutely clean ultrasonic technology for nonwovens makes this possible. Materials are joined by means of locally limited heat generation:
Ultrasonic welding ensures maintained functionality of the components and provides continuous process monitoring unrivaled by other processes. Up to 130 different process reference data are available and can be visualized:
Sensors and electrical components are not only used in industrial manufacturing but also in automation engineering or in daily use. Ultrasonic welding is particularly suitable for their production and complies with product requirements, such as:
Nowadays, the requirements of battery products have become increasingly diverse and complex: In addition to precision, strength, and minimum particle formation, process validation and traceability are equally important quality criteria. Ultrasonic welding qualifies as the best suitable joining technology:
Using ultrasonics, consumer components can be produced and joined in a cost-effective way; at the same time, the process provides great flexibility in terms of design. High requirements for visual appearance, production speed, or geometry are met.
The demand of the production industry for complex and efficient automatic systems is constantly increasing. Herrmann Ultraschall therefore offers a wide range of solutions for integration of ultrasonic systems and components.
Did you know? A large number of every-day products are welded using ultrasonics. Our technology is used in many different industries to permanently bond plastic materials and nonferrous metals.
This machine series allows for complex ultrasonic joining of injection molded plastic parts and nonferrous metals. Thanks to intelligent software and variant diversity, the ultrasonic welding machines can be specifically configured to your demands:

Industrial ultrasonics is an acoustic principle. Vibrations are turned into heat and thus the plastic material melts, which results in a homogeneous joint. Metals are joined through molecular bonding caused by the vibration. Let us explain the principles in detail and show you the large number of fascinating application options.
