Advantages of Ultrasonic
Ultrasonic bonding is a reliable, well-established, and environmentally
friendly process that utilizes ultrasonic vibrations to fuse synthetics
and nonwoven materials. This bonding method does away with the need
for needles, thread, adhesives, or other consumables, while also
eliminating related concerns about stitch holes, glue gaps, and
Sonobond's ultrasonic bonding process is completed
in only seconds, takes up a minimal amount of material at the seam,
and provides a much stronger and dependable bond than is produced
with stitching, glue, or hot air methods. Sonobond bonders have
the added advantage of being four times faster than sewing machines
and ten times faster than adhesive machines. The equipment is also
easy to operate and requires minimal training. Sonobond's ultrasonic
technology is so reliable that it is used to assemble the disposable
medical apparel that helps protect personnel from hazardous fluids.
Machines for Every Application
Sonobond's extensive and versatile line of ultrasonic bonding equipment
enables manufacturers to choose the machine or machines best suited
for their specific requirements. Here is a brief overview of the
bonders most often selected for filtration assembly.
The Sonobond SeamMasterT Series features ultrasonic
machines that seal, sew, and trim material in one quick, continuous
rotary process. This equipment can be set up as a stand-alone unit
or incorporated into production lines.
Although similar in appearance and operation to
a traditional sewing machine, the Sonobond SeamMaster uses no 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.
Sonobond's SeamMaster High Profile Bonder features a high clearance
between the wheel and horn. This makes it ideal for hand-guided
applications with tight tolerances and for working around curves.
An important feature of this machine is the availability of a special
fixture for bonding pleated filters.
Numerous manufacturers use this versatile machine
for filtration assembly purposes. For example, American Air Filter
International utilizes this equipment to assemble various types
of commercial air filters, such as those used for HVAC, dust collection,
nuclear, and bio-chemical applications. Enfilter Limited bonds the
longitudinal seams of its liquid and gas filter cartridges. EvoOrganic
puts together environmentally friendly filtration fabrics for agricultural,
landscape, and garden products. Kuss Filtration uses the High Profile
bonder in assembling its fuel filters. Supply Pro assembles oil-absorbent
pads, booms, and pillows with the machine, and Velcon Filters utilizes
this ultrasonic equipment to create filtration components for commercial
and military jet fuel handling.
Sonobond's SeamMaster High Profile
Ultrasonic Bonder is an easy-to-operate machine and is available
with a special fixture for bonding pleated filters. It is
used to assemble jet fuel filters, commercial air filters,
oil-absorbent booms, and much more.
Sonobond's ultrasonic equipment is
used to assemble filters and filtration products for a wide
variety of industries. Ultrasonic bonding is much faster than
sewing or adhesive methods.
Box-Style Filters, Filter Bag Ends
Sonobond's SureWeldT 20 Ultrasonic PlungeBonderT is a powerful,
dependable, multi-use machine that is ideal for sealing large, multi-layer
and difficult-to-bond materials in just one hit. It is often used
for sealing box-style filters and filter bag ends. This machine-as
well as its welding horns and nests or fixtures-can be customized
for specific applications. For example, a special two-head version
is used by American Air Filter to assemble cube filters. Other manufacturers
utilize this equipment for such applications as assembling automotive
air filters and HEPA-rated filters used in bag-less vacuum cleaners.
Filter Bag Assembly
Sonobond's award-winning RingMasterT Filter Bag Machine is specially
designed for the high-quality, high-volume assembly of heavy-duty
filter bags used for a variety of chemical and industrial liquid
applications. This innovative ultrasonic bonder joins the plastic
collar to felted filter media to create a dependable 360° bond.
The entire process is completed in two steps, takes less than ten
seconds, and produces up to 250 bags per hour. Custom tooling is
available to accommodate a variety of bag sizes and ring diameters.

The Filter Collar BonderT is designed for lower-production
assembly of bag filters. The unit creates a reliable 360° weld
between the bag and the plastic ring in as little as 45 seconds.
Between 50 and 80 bags per hour can be assembled in this way.
Free Viability Test
Because Sonobond has such an extensive number of ultrasonic bonding
machines, the company offers a no-cost, no-obligation Ultrasonic
Bonding Viability Test to help determine the equipment best suited
for any specific application. Filtration assemblers are encouraged
to provide materials so that sample bonds can be made. Once it is
decided to install a Sonobond machine, this work is completed as
quickly as possible, with minimal disruption to the customer's production
process. Sonobond also provides prompt, dependable technical support
before, during, and after installation.
