The SeamMaster High Profile Ultrasonic Bonder is especially popular among ballistic vest manufacturers. The machine is ideal for sealing the outer nylon shell of body armor to protect the ballistic-resistant material inside. A reliable seal means there is substantially less risk that the bullet-proof materials contained in the vest—such as Spectra-Shield and Kevlar—will lose their life-saving effectiveness by being exposed to moisture. In fact, the seams produced by this Sonobond equipment are so perfectly fused that they meet current National Institute of Justice (NIJ) wet-conditioning standards that mandate protection from submersion for half an hour, rather than protection from a spray shower.
The SeamMaster High Profile Ultrasonic Bonder features a rotary system for rapid sealing, sewing, and trimming of synthetic fabrics. Although similar in appearance to a traditional sewing machine, it has a large wheel with a high clearance above the bench. This provides fast, easy access for bulky materials and hand-guided operations. It is also up to four times faster than conventional sewing machines and ten times faster than adhesive methods. This equipment is also available as a modular unit for convenient integration into production lines.
The SureWeld 20 Ultrasonic PlungeBonder is another Sonobond machine that offers important advantages to ballistic vest assemblers. This powerful equipment is capable of sealing large, multiple-layer or difficult-to-bond materials. It is perfect for ultrasonically bonding coated straps within the seam of a ballistic vest’s outer shell. The bond is accomplished in one pulse without compromising the integrity of the ultrasonically sealed outer shell. As a result, the body armor continues to meet NIJ submersion standards.
