WEST CHESTER, Pa. – Leading manufacturers of outdoor-use protective coverings use Sonobond Ultrasonics bonding equipment to produce ultrasonic leak-free seams. These contribute to providing enduring product quality and effectiveness.
Manufacturers of many types of protective coverings that require impermeable seams can benefit, including those used for cars, RVs, motorcycles, utility and all-terrain vehicles, boats, and snowmobiles; outdoor furniture covers and cushion liners; barbecue grill covers; and even protective envelopes for product shipments.
Ultrasonic technology offers unparalleled efficiency, speed and reliability for ultrasonically joining fabrics that are 100 percent synthetic or fabric blends that contain up to 40 percent natural fibers.
Ultrasonic Technology for Bonding Assembly
Sonobond’s assembly equipment requires no glue, thread, needles or other consumables, eliminating problems caused by glue gaps, thread breakage, color changes, stitch holes, fraying and unraveling. Instead, high-frequency vibrations are channeled into synthetic and synthetic-blend fabric as it passes between an ultrasonic unit’s horn and anvil. The vibrations create a rapid heat buildup that causes the material’s synthetic fibers to soften and fuse. The result is bonded seams with a strong molecular seal impervious to potential incursion and damage from pervasive environmental contaminants such as sap, salt, snow, bird droppings, acid or freezing rain, and roadway debris.
Sonobond equipment can also reach production speeds up to four times faster than conventional sewing methods, and 10 times faster than adhesive assembly systems, so it’s highly cost-effective. Some manufacturers have boosted output by as much as 25 percent using ultrasonic assembly.
Equipment Options
Sonobond offers two types of ultrasonic bonding units especially applicable for assembling protective coverings. Though similar in appearance and operation to a traditional sewing machine, Sonobond’s SeamMaster® High Profile Ultrasonic Sewing Machine has a high clearance between the wheel and horn, allowing increased access for hand-guided applications with curves and tight tolerances. The unit can seam, trim and seal in one step, and offers a wide selection of interchangeable pattern rollers that also hem, emboss and print. The machine requires minimal training to operate and by combining several operations into just one pass, it saves labor, time and money. It is also available as a modular unit that can be integrated into production lines.
For bulky, large, multiple-layer and/or difficult-to-bond materials, Sonobond offers the SureWeld™ 20 Ultrasonic PlungeBonder™. A combination of a rugged welding press and heavy-duty power supply, the welding horns and nests or fixtures of this unit can be customized, allowing it to achieve customers’ specific applications with superior repeatable performance.
Bondable Fabrics
Materials best suited to Sonobond’s ultrasonic bonding include polypropylene, polyester, nylon, acrylics, PVC and materials coated with thermoplastic urethanes. They can be configured as wovens, nonwovens, knits, films and laminates. Acrylics such as those used for awnings can be edge cut and sealed to prevent fraying.
Ultrasonic Bonding Viability Test
