According to Herrmann, many processes such as lamination, cutting or embossing can be implemented by means of ultrasonic technology; advantages including a clean and sustainable process, high speeds and reproducibility. Additionally, the data evaluation allows a quality control like no other method, the company says.
For many nonwoven applications, ultrasonic welding offers an alternative to gluing or thermo-bonding. But without solid consultation and support in the ultrasonic laboratory, feasibility and cost-effectiveness cannot be assessed.
The company therefore provides seven steps to a good welding result as part of its Ultrasonic Engineering porfolio:
- Application consulting - Standing or rotary welding, process comparison
- Testing the ultrasonic weldability - Material testing, assessment of basis weight, structure of the layers, melting point
- Anvil design - Roll structure, pin design, pressing surface
- Welding process development - Parameter optimization, measurement verification of product requirements
- Integration in machine environment - Consulting on installation concept, material management, interfaces
- After-sales service - Process optimization, preventative mainenance, 24-hour hotline
- Knowledge transfer - Basic and expert training in ultrasonic welding technology
