Continuous Ultrasonic Welding
With our continuous ultrasonic welding technology we offer you processes for joining, welding, laminating, embossing, and cutting of nonwovens, textiles, and plastics. Among other things, the products and systems of Hermann Ultrasonics are used for high-volume production in the textiles, medical, hygiene, filter, and general technical industries. Customers appreciate the consistently high-quality and controlled weld quality at high speeds. This allows the realization of complex applications with user-friendly, very simple handling.
ULTRASONIC – the advantages of a new connection technology
No lead times for heat-up phases
Low energy costs, since ultrasonic weld tools do not require heat-up
No contamination by adhesives - cost savings in handling and maintenance
Production of up to 800 m/min with reliable weld quality
Welding, cut & seal, laminating, embossing, perforating, compacting, or cutting
Manufacturing technology for premium products with consistent material properties and optimal hand feel
Applications for Continuous Ultrasonic Welding
Ultrasonic welding equipment can be readily incorporated into nonwoven fabric sealing machines for laminating material and the production of items such as:
Diapers
Filters
Femcare
Cosmetics

Basic knowledge: Laminating nonwovens and web materials
The general principle of ultrasonic welding can also be applied to nonwovens. The thermoplastic fibers are activated by mechanical vibrations thus melting and bonding in pre-defined patterns. Under what conditions is ultrasonic joining suitable for nonwovens? More basic knowledge on laminating of nonwovens and examples for applications, as well as an overview of various weld geometries is available here. Basic knowledge
Core Applications
LONGITUDINAL SEAL: When welding nonwovens in combination with longitudinal seals, high-strength connections are established at the joint areas. Rotary ultrasonic systems are particularly suitable for joining applications in marginal areas.
