Rotary ultrasonic bonding is the process of using high-frequency compression/relaxation of materials against specially designed anvil patterns that cause them to heat at the molecular level and melt. This process enables the materials to flow around the shapes of the anvil and adhere to each other and to other materials that are in the web matrix.
Fastest sealing speed in the industry with focused energy and the “flywheel effect” of the rotary system. Cross or end seal through product or residue without the worry of burning or contaminating the packaged product. Reduce scrap rate by bonding materials with localized heat input, programmable control, and failed seals during shipment are a thing of the past. Packages are sealed strong enough to survive temperature and air pressure changes during transit for distribution.
Save time by eliminating bagging of your sealing unit in washdown environment
Uniform Melt & Hermetic Seal with molecular bonding
GO GREEN by reducing energy consumption and by easily sealing recyclable and paper based materials
Our patented Rotary Ultrasonic bonding technology provides high-speed continuous or intermittent bonding of nonwoven materials. Rotary ultrasonic bonding is suitable for many different applications including fin and lap sealing, tube forming, bonding, feature attachment, embossing, sheet lamination, cutting, and slitting.
Higher productivity with high speed rotary technology (800 meters/minute) and lower process delay time
Reduces material weight by eliminating adhesive
Energy savings by eliminating adhesive dispensing systems (heater and pump)
Dukane’s line of ultrasonic products offer clean, consistent and fast processing for joining and cutting nonwoven materials. From quilting mattress pads and sewing disposable health care apparels to slitting and bonding hygiene products we have designed and delivered a solution for all major film and fabric applications.
Packaging
Ultrasonic package sealing occurs when high frequency (ultrasonic) mechanical energy is transferred into two or more layers of thermoplastic materials. A strong, reliable molecular bond is formed between the layers. Nearly all packaging materials and laminates, with a thermoplastic sealing layer or coating, are suitable for the ultrasonic sealing (welding) process.
Ultrasonic Cutting
Dukane ultrasonic systems are widely used for cutting thermoplastics, textiles, films, rubber, wovens and non-wovens, and many aerospace materials. These versatile cutting systems can be operated as hand-held units or incorporated into automated solutions.
