Sonobond‘s Ultrasonic SeamMaster^® High Profile Sewing Machine and PlungeBonder^TM utilize ultrasonic vibrations to:

• soften and fuse synthetic fibers together
• seal the seams of the inner nylon protective envelope, or cover, that surrounds the ballistic material in body armor,
• attach coated straps to the cover without compromising the seam integrity, and
• create a barrier that keeps the seams secure even after submersion for 30 minutes.

Ultrasonic Assembly Achieves Effectiveness and Efficiency

The SeamMaster^® High Profile Ultrasonic Sewing Machine:

• operates similar to a traditional sewing machine, requiring minimal operator training,
• bonds and trims in one step, making it four times faster than conventional stitching and 10 times faster than adhesive methods,
• fuses woven or nonwoven synthetic materials, or blends with up to 40 percent natural fibers, without stitch holes, glue gaps, fraying or unraveling,
• uses only a minimal amount of material at the seam, and
• has high clearance for hand-guided operations and easy assembly of bulky materials.
