Sonobond's Free, No-Obligation Ultrasonic Bonding Viability Test Helps Companies Find Practical, Cost-Effective Solutions for Their Textile and Filtration-Assembly Applications

Sample ultrasonic bonds are made using materials supplied by prospective customers.  Sonobond then recommends the appropriate ultrasonic bonding equipment to match each firm’s specific needs and requirements.

WEST CHESTER, PA - Janet Devine, President of Sonobond Ultrasonics, announced today that the company's free Ultrasonic Bonding Viability Test is proving to be very important to firms in both the textile and filtration-assembly fields.  She says, "When manufacturers or assemblers take advantage of this no-charge, no-obligation opportunity to have us make sample bonds from materials that they themselves supply, they see firsthand the practicality of our ultrasonic bonding process.  This also lets our technical team recommend the Sonobond ultrasonic bonding equipment best suited to that company's particular requirements."

Ultrasonic Bonding Offers Important Advantages

Ultrasonic bonding is a reliable, well-established, environmentally-friendly process.  No needles, thread, adhesives, or other consumables are required. 

Sonobond bonders channel high-frequency vibrations into synthetic and nonwoven material as it passes between the ultrasonic unit’s horn and anvil.  The resulting rapid buildup of heat causes the material’s fibers to melt and fuse.  The bond is completed in seconds and is often stronger and more dependable than can be obtained from stitching, glue, or hot air methods.  These factors make ultrasonic bonding practical, popular, and cost-effective.  Materials best suited for ultrasonic bonding are 100 percent synthetic or blends with up to 40 percent natural fibers.  

Ultrasonic Bonding for a Broad Range of Products

President Devine reports that Sonobond's ultrasonic bonding equipment is used by a growing number of companies and for a wide variety of applications in both the textile and filtration-assembly fields.  She says, "Occasionally, manufacturers or assemblers may be skeptical that our machines can effectively bond the woven fabrics or nonwovens they use.  They challenge us to 'prove' that ultrasonic bonding will accomplish what they want.  And that's exactly what we do through our Ultrasonic Bonding Viability Test.  Once people see the advantages of ultrasonic bonding and the way Sonobond equipment delivers fast, strong, reliable results, we can customize our machines to their specific requirements." 

Materials that can be bonded include polypropylene, polyester, nylon, acrylics, vinyls, PVC, and thermoplastic urethanes.  These may be constructed as wovens, nonwovens, knits, films, or laminates.  End products include ballistic vests, draperies, window shades, garments, blankets, medical apparel and disposables, awnings, athletic accessories, automotive seats and carpets, banners, flags, aviation insulation panels, netting, ribbons, and more.

Sonobond bonders can also be used for ultrasonic assembly of filtration products for the airline, food, paper, pharmaceutical, air and water filtration, liquid absorption, petroleum, and agricultural fields.  Ms. Devine says, "No other manufacturer offers such an outstanding variety of ultrasonic bonding equipment for filtration assemblers.  In addition, these bonders can be customized to each company's specific needs, either as stand-alone units or incorporated into a production line."

Successfully Bonding New Types of Fabrics and Nonwovens

Recent years have seen a dramatic increase in the types of fabric available for consumer and commercial applications.  A new wave of nanotechnology is leading to the development of textiles that are more durable, resistant to spills and wrinkles, and more comfortable to wear.  At the same time, there has been a substantial growth in the use of nonwoven filtration fabrics.  This follows developments in fine micron filtration technology for the chemical, food, pharmaceutical, semiconductor, and other industries, as well as increasingly stringent environmental standards in various fields.

According to President Devine, Sonobond technology is proving equal to these developments.  She says, "We have companies coming to us and asking whether their new woven or nonwoven materials are suitable for ultrasonic bonding.  I'm happy to report that in most cases our machines do an excellent job on these materials.  And we demonstrate this by providing sample bonds made on our equipment."

It's Easy to Arrange an Ultrasonic Bonding Viability Test

Ms. Devine explains that it is very easy to have sample bonds made.  She says, "Companies can visit our website at and click the button requesting the Ultrasonic Bonding Viability Test.  There is a short form asking for some basic information that can be completed in just a couple of minutes.  As soon as we receive this, we respond promptly.  Of course, firms can always call us if they prefer.  We're often able to determine upfront whether an application seems feasible.  If we believe it is, we'll let the company know the amount of sample material needed and discuss such pertinent information as whether they want us to seam and/or trim."  

"Once we have received the materials from the prospective customer, we make every effort to do the test and get back to them with sample bonds within a week or so.  But let me emphasize that taking advantage of our Ultrasonic Bonding Viability Test does not obligate a company in any way.  Although Sonobond equipment is very cost-effective, we realize that it represents a capital investment.  So we understand that firms need to confirm to their complete satisfaction that our machines will provide the result they want for their particular application."

Sonobond Leadership in Ultrasonic Bonding

Sonobond offers a wide range of ultrasonic bonders for textile and filtration applications.  Here are a few outstanding examples:

Sonobond’s SeamMaster™ Series features machines that seal, sew and trim in one quick, continuous rotary process.  This equipment is very similar in appearance and operation to traditional sewing machines.  However, these ultrasonic bonders are up to four times faster and do not use needles or thread.  Fraying and unraveling of bonded edges and seams are virtually eliminated.  Customers can select from over 500 standard pattern wheels—plus custom designs—for slitting, sealing, seaming, embossing and tacking.

The SeamMaster™ High Profile Bonder is one of the most popular machines in the SeamMaster Series and features a high clearance between the wheel and the horn.  This makes it well-suited for a wide variety of textile-assembly requirements, including hand-guided applications with tight tolerances and working around curves.  A special fixture for bonding pleated filters is also available. 

Sonobond's award winning RingMaster™ Filter Bag Machine is specially designed for the high-quality, high-volume assembly of heavy-duty filter bags needed for various chemicals and for industrial liquid applications in the food, paper, pharmaceutical, and petroleum fields.  The machine attaches a plastic collar to felted filter media in a two-step process.  This creates a dependable 360°bond in less than ten seconds.  The RingMaster is capable of producing up to 250 bags per hour in this way. 


The SureWeld™ 20 Ultrasonic PlungeBonder™ consists of a rugged welding press and a heavy-duty 1000- to 3000- watt power supply.  It is ideal for sealing large, multi-layer, and difficult-to-bond materials in just one hit.  The PlungeBonder is often used for sealing box-style filters and filter bag ends.

Ms. Devine says, "These machines are just a few examples of how Sonobond technology is answering the growing demand for fast, cost-effective ultrasonic bonding across a wide range of fabric and filtration applications.  Manufacturers and assemblers are encouraged to contact us to learn more about the Sonobond equipment available to them."
