Sonobond Ultrasonics' Bonding Technology Gains Momentum in Medical Product Manufacturing


Ultrasonic Bonding Provides Quick, Reliable, CVost-Efficient Production Without Consumables

WEST CHESTER, Pennsylvania, February 28, 2007 - Sonobond Ultrasonics announced today that its ultrasonic bonding technology is continuing to gain momentum in medical product manufacturing as medical professionals demand better infection control and as manufacturers become more aware of the advantages ultrasonic technology offers. Faster and more efficient than conventional sewing and adhesive methods, ultrasonic bonding provides reliable, durable, and cost-efficient production without the use of consumables.

Numerous Applications in Medical Products Production
Ultrasonic technology has proven ideal for achieving secure barrier protection and comfort in synthetic textile and nonwoven medical products.
"That's been especially important as medical professionals have steadily converted from reusable to disposable products to avoid handling and spreading

contaminants," says Janet Devine, president of Sonobond Ultrasonics.
Ultrasonic bonding also has many other applications in the medical products field - from attaching Velcro® straps to flexible casts and other orthopedic devices, to manufacturing surgical repair products, such as hernia patches.

Benefits of Ultrasonic Assembly
Ultrasonic vibrations actually fuse nonwoven and synthetic materials. There's no need for thread, glue, or needles, so stitch holes and glue gaps are eliminated, decreasing the risk of contamination. Ultrasonic bonding also reduces fraying and unraveling of edges, leading to further product comfort and durability. Sealed ultrasonically, medical products, such as hospital mattress covers and body bags, provide secure barrier protection. Likewise, surgical masks, gowns, and drapes have soft, reliable, non-abrasive seams that meet tough regulatory requirements and protect medical personnel from potentially hazardous fluids. Plus, ultrasonic assembly is quick, reliable, and repeatable, assuring accurate and durable assembly of medical products.
Easy, Fast, Efficient Production Sonobond Ultrasonics' bonding machines require minimal training. Its SeamMaster(TM) machines are as easy to use as conventional sewing machines, yet up to four times faster - cutting, trimming, and sealing in just one pass. They also work at up to 10 times the speed of adhesive methods, making them exceptionally cost-effective.

The SeamMaster(TM) High Profile Bonder and SeamMaster(TM) 10 Ultrasonic Cutter/Sealer perform hand-guided applications with tight tolerances or curves. Capable of running at speeds of up to 60 feet per minute, they work with a wide selection of interchangeable pattern wheels that slit, emboss, and stitch. The SeamMaster(TM) 10 is a tabletop unit and the SeamMaster(TM) 86 High Profile Bonder is a free-standing unit available in modular form for integration into production lines. It also has an optional speed-up kit to increase operation up to 120 feet per minute.
For single-weld operations, Sonobond offers the SureWeld(TM) 20 PlungeBonder(TM). Its rugged welding press bonds synthetic textiles of varying thicknesses and multiple layers in just one pulse. It's also ideal for attaching Velcro® to casts.
