Ultrasonic welding technology for

Plastics Packaging Nonwovens Metals

Ultrasonic welding means joining without adhesives, screws or heat from an outside source. During this process, material is strategically melted by means of ultrasonic vibrations so that a cohesive or form-fit joint is produced. As economic production method with short cycle times, ultrasonic welding ensures a large degree of process control and repeatable quality results.

AUTOMOTIVE

Highest weld quality: Vehicle parts must be joined to be tight, strong, dimensionally accurate and visually impeccable. Ultrasonic welding is a fast and economic solution for this complex task.

FOOD

For packaging with thermoplastic sealing layers, such as capsules, pouches, drink cartons, cups and trays, ultrasonic sealing provides a large number of options: above all, high cycle rates and tight seals despite potential product residues in the seal area.

HYGIENE

Ultrasonic welding of nonwovens is an extremely fast and stable process that is easily repeatable and directly available without the need for pre-heating. The technology allows for simultaneous embossing, laminating and cutting.

MEDICAL

The requirements for quality and safety of medical parts are very high: in addition to tightness, strength and minimal generation of particles, process validation and process stability also are important factors in manufacturing.

ELECTRONICS

The requirements of components for the electronics industry have become increasingly complex and wide-ranging: Tightness, accurate dimensions, and the impeccable visual appearance of surfaces are typical quality criteria.

BATTERY

Highest weld quality: Process visualization and process stability provide for product safety and repeatability. Small footprint for easy integration into production lines. Ultrasonic metal welding is the ideal solution for maximum quality in production.

CONSUMER

Individual requirements for the wide range of consumer components are very high: tightness, strength, dimensional accuracy, perfect visual appearance and surface finish are standard.

AUTOMATION

The concept of automation covers different fields of application for ultrasonic technology: Weld systems integrated in an automatic system, individual components used in special-type welding machines, or flexible use in robot cells.

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.

News

Using data to achieve the perfect packaging process

Data is also the new oil in the packaging industry: it helps to make the process even safer, even more efficient and even faster. We show how companies can digitize their packaging process with ultrasonics to gain a competitive advantage.

How to reduce rejects in the packaging process

Despite increasing cost pressure, many companies have accepted the high reject rates in the packaging of food and animal feed. Yet the most common reason for rejects in packaging machines can be easily avoided - with ultrasonic sealing technology.

News

Enhance the reliability of sealing sustainable materials

The latest generation of Herrmann Ultraschall's longitudinal seal module (LSM) ensures reliable longitudinal seals for applications like pillow bags, even with the narrowest of process windows. Regardless of variations in the speed of flow wrappers or other packaging machines, the LSM ensures seals with a visually flawless appearance.
