Ultrasonic technology for fast, cost-effective and flexible welding processes
High production speed, increased quality and optimum process reliability for protective mask welding
Not only since the outbreak of the COVID-19 disease manufacturers of hygiene and medical products made of nonwovens rely on ultrasonic welding. Although wearing a face mask as self-protection for an infection with viruses is controversially discussed, ill persons can contribute to the protection of their environment by wearing a suitable mask. Ultrasonic welding systems from Weber Ultrasonics can be perfectly integrated into automated processes for the mass production of all types of mouth and respiratory protection masks made of nonwoven materials.
The welding, laminating, cutting and embossing of non-woven and web materials with ultrasound offers numerous advantages compared to thermal solutions or adhesive processes. Ultrasound is more reliable, productive, cost-effective and safe. Welding of nonwovens with ultrasound guarantees soft and flexible surfaces, as no radiant heat that causes hardening occurs during welding. This apply to both continuous and clocked welding processes.
The energy input is precisely and targeted so that web materials do not become warped. Cross seams required for hygiene products are implemented perfectly thanks to this precision.
What‘s more, temperatures remain low despite long process times. Unlike thermal procedures in which the tools are permanently heated, there is no risk of fire. Compared to thermal procedures, energy consumption is minimal.
There is no need for adhesives when using ultrasound. This raises the added value of the end products, as some adhesive ingredients can trigger allergies. Moreover, when ultrasound is used, no adhesive residues build up on rollers and pulleys in production. The process is cleaner and more environmentally friendly.
Weber Ultrasonics offers technology and service from a single source: with certified quality, developed and manufactured in state-of-the-art production facilities in Germany. The company‘s portfolio comprises ultrasonic components such as generators or sonotrodes, as well as complete, turnkey systems with integrated quality control and individual additional functions. Concise customer training courses and a unique customer service with ultra-fast spare part delivery round off the portfolio.
