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.
