Leading ballistic vest manufacturers rely on Sonobond Ultrasonics’ equipment to help them comply with the tough standards set by the National Institute of Justice (NIJ).
These standards mandate that body armor must be totally waterproof. (See NIJ-0101.06.) Sonobond’s SeamMaster High Profile Ultrasonic Bonder is regularly used for sealing the outer shell that protects the ballistic-resistant material inside the vests. The unit’s rotary system seals, sews and trims the nylon fabric in one quick, reliable step that uses no thread or other consumables.
Now manufacturers can rely on another Sono_bond unit, the SureWeld 20 Ultrasonic PlungeBonder with custom tooling, to ultrasonically bond straps within the seam of the vest’s outer shell. This is a separate operation that does not compromise the integrity of the ultrasonically sealed outer shell. As a result, manufacturers are able to continue producing ballistic vests that comply with current NIJ submersion requirements.
