A Wide Variety of Important Applications
Sonobond’s ultrasonic sewing machines bond fabrics that are synthetic, blends containing up to 40% natural materials, and nonwovens. They create ultrasonic fabric bonds that are strong, regulatory-compliant, and fully sealed. Applications include:
- General purpose sewing
- Lacing and quilting
- Medical disposables
- Cuffs and sleeves
- Ribbons and trims
- Ballistic vests and body armor
- And much more
The first SeamMaster® Ultrasonic Sewing Machine was introduced in October 1991 to meet demands for safer medical garments and disposable items. It has since been awarded trademark registration for its use of high-frequency vibratory waves that produce secure barrier seams and bonded edges without stitch holes, glue gaps, fraying or unraveling.
Assembly Applications Skyrocket
Applications for SeamMaster® Ultrasonic Sewing Machines have exploded over the past three decades, in part due to the equipment’s versatility, minimal training requirements and more than 500 interchangeable pattern rollers. They are used for slitting, lace making, embossing and stitching, and provide assembly solutions whenever sewn seams are not adequate to satisfy end-use requirements.
PPE and medical fabric items include: face masks; surgical and hospital gowns; disposable shoe, pillow and mattress covers; sterilization and storage pouches for medical instruments; lint-free wound dressings; hazmat gear; body armor, and ballistic components.
Filtration products include: pleated, HVAC and HEPA filters; air, liquid and gas filters; acoustic and insulation panels for automotive, transportation, and aerospace use; heavy-duty filter bags for food, chemical, pharma and household use; and oil containment booms and spill clean-up cloths.
Creating Ultrasonic Fabric Bonds
SeamMaster® Ultrasonic Sewing Machines look and operate like traditional sewing machines, using ultrasonic vibrations instead of needles or thread to cut, sew and trim in one pass—at speeds up to four times faster than conventional sewing machines. The units use a patented rotary operation, where both horn and pattern wheel rotate at the same time to produce ultra-reliable, soft-to-the-touch seams.
Sonobond’s equipment can ultrasonically bond fabrics and other materials that are synthetic or blends containing up to 40% natural fibers. The high-frequency vibrations cause the synthetic fibers to soften and fuse, creating a durable seal without the gaps caused by glue—and at speeds up to 10 times faster than with adhesive methods.
Variety of Models
In addition to its first general purpose ultrasonic sewing machine, Sonobond offers SM10 table-mounted ultrasonic cutter/sealer units and modules for OEM integration.
The SeamMaster® Ultrasonic High Profile Sewing Machine is currently the most popular model because of its large pattern wheel, high clearance, and ability to accommodate bulky materials and hand-guided operations with tight tolerances and curves. In fact, the machine is used by most major manufacturers of body armor throughout the world to seal the inner shell of body armor and produce a bond so reliable that it complies with NIJ submersion standards to protect the ballistic-resistant materials from water leaks.
