Sonobond’s Ultrasonic Bonding Technology Increasingly Essential for Ensuring Reliable Body Armor Assembly
More than 30 Leading Manufacturers Use Sonobond Equipment to Achieve Improved Production Speed, Product Durability, Cost-Effectiveness and Compliance with Tough NIJ Standards
With armed services personnel, emergency responders, law enforcement officers, and others exposed to more and more perilous circumstances, reliable body armor is absolutely essential for their personal safety. That’s just one of the reasons why more than 30 leading manufacturers use Sonobond’s ultrasonic technology to assemble their ballistic vests.
“Instead of needles, thread or glue, our equipment uses ultrasonic energy to create strong molecular bonds, resulting in durable, perfectly sealed seams without stitch holes, glue gaps, fraying or unraveling,” explains Sonobond Vice President Melissa Alleman. “Sealed seams mean better protection for the bullet-proof materials contained in the vest – such as Spectra-Shield® and Kevlar® – ensuring that they are less likely to lose their life-saving effectiveness by being exposed to moisture. They also achieve compliance with National Institute of Justice (NIJ) wet-conditioning standards (NIJ-0101.06) requiring body armor to be waterproof, even after submersion for 30 minutes.”
The ultrasonic energy – directed into woven or nonwoven synthetic materials or blends with up to 40 percent natural fibers – results in a rapid heat buildup that causes the synthetic fibers to soften and fuse, creating the strong molecular bond.
Ultrasonic Equipment for Body Armor Assembly
Sonobond’s SeamMaster® High Profile Ultrasonic Sewing Machine is perfect for sealing the outer nylon shell of body armor. Its rotary system seals and trims in one quick step, making assembly up to four times faster than with conventional sewing machines and 10 times faster than adhesive methods. In fact, some manufacturers have increased production output by as much as 25 percent since switching from sewing and adhesives machines to ultrasonic bonding technology.
The SeamMaster® High Profile Ultrasonic Sewing Machine operates like a traditional sewing machine so only minimal training is required. It is also available as a modular unit for integration into production lines.
A second machine that’s useful for body armor assembly is Sonobond’s Ultrasonic PlungeBonderTM. It’s ideal for attaching coated synthetic straps within the seam of a ballistic vest’s outer shell without compromising its integrity, again ensuring the vest’s ability to satisfy NIJ submersion standards. The machine can easily attach straps at a rate of five vests per minute.
