35Khz Ultrasonic Welding Equipment for Non-woven Fabric Welding Hygiene Industry

Ultrasonics is a clean and efficient method of joining or slitting synthetic materials.While the initial investment is much more, the long term benefits more than pay for itself.

Ultrasonic bonding uses high frequency sound to generate localized heat through vibration and causes thermoplastic fibers to bond together. Suppliers in the industry say the technology offers several advantages.

Ultrasonics creates a mechanical bond rather than a chemical bond created by adhesives. Mechanical bonds tend to hold up better in extreme heat conditions such as may be incurred during transportation in certain geographies. Being chemical-free is also of potential benefit to the environment and end users with sensitive skin.

Because ultrasonic bonding uses friction and pressure to bond materials directly to each other, it makes the added cost of glue and solvents, as well as the cost for added fixturing and the time for glue to “set-up," unnecessary. In addition, it eliminates glues and solvents as potential sources of contamination along with the need to clean and maintain glue and solvent application equipment. Because ultrasonics can bond over a range of frequencies and with varied levels of downforce, it also reduces the risk of damage to even the most delicate nonwoven materials and filter media.
