Let Us Prove We Can Produce the Secure Seams You Require Before You Place Your Order
Schedule our no-charge, no-obligation Ultrasonic Fabric Bonding Viability Test and we will produce sample assemblies using your own nonwoven or synthetic material.
This test will verify the quality and strength of our leak-proof seams and determine which Sonobond unit is right for your application.
Advancing Ultrasonic Assembly Applications
Our first ultrasonic sewing machines were introduced over three decades ago to satisfy OSHA requirements for strong, fully sealed barrier seams in medical garments and disposable items.
Since 1991, applications for our ultrasonic textile bonding equipment have proliferated, especially where traditional sewing or gluing cannot achieve durable, leak-proof seams. Our machinery utilizes high-frequency sound waves that quickly cause heating and plasticization of nonwoven and synthetic materials, creating high-quality bonds at pressure points that eliminate liquid wicking that can occur from stitch holes, glue gaps, fraying or unraveling.
SeamMaster® Ultrasonic Sewing Machines
Manufacturers most often request our SeamMaster® Ultrasonic Sewing Machines because of their high-quality, repeatably-accurate output and ease of use. Their advantages include:
- Continuous, patented rotary operation that creates strong, sealed, smooth, and soft-to-the-touch seams,
- Minimal training, since they resemble and operate like conventional sewing machines, but without using thread or other consumables – so you can reduce your production costs,
- Bonding, seaming and trimming accomplished in one quick step – at speeds up to four times faster than traditional sewing machines and ten times faster than adhesives machines – so you can achieve greater production output.
Producing Free Sample Fabric Bonds Using Your Own Materials
Once we’ve received your instructions as noted on our brief form, and your synthetic woven or nonwoven materials, we’ll conduct your free, no-obligation Ultrasonic Fabric Bonding Viability Test. We’ll ensure that your specifications are met and verify the Sonobond bonder best suited for your application. You’ll see the results before you buy.
