Acoustic welding, and more particularly ultrasonic welding, has become increasingly popular in a number of industries. For example, businesses in the textile and personal products industries often manufacture products such as diapers, clothing, etc., that are ultrasonically welded. Ultrasonic welding tools operate under the principle of applying acoustic energy in the ultrasonic frequency range (i.e., at or above 20 kHz) to a horn. The horn vibrates in response to the applied acoustic energy to further produce an output acoustic energy.
Ultrasonics is also the method of choice for these materials, for example for parting fabrics so that there is no thickening of the material along the cut edges.
No consumables such as glue, staples or sewing thread are needed. The fabric remains intact, because no external thermal energy is directed into the fleece. Position, shape and displacement of the welding points can even support the desired properties of the composite.
Characteristics:
1. Seamming,trimming and embossing without glue, thread or other consumables
2. More faster and cost effective than traditional sewing machine and adhesive ways
3. Eliminates fraying or unraveling of bonded edges and seams
4. Multifunctional and thousands of designs available
5. Requires minimum training and maintenance
6. Super strong ultrasonic power meets the needs of different fabric thickness
There are two types of rotating modules for these operations: with either a side or central sonotrode resonating at a 35 kHz frequency and power varying from 600W to 1200W.
These horns can be made out of aluminium, treated with a special surface strengthening procedure, or titanium.
Our seam welding solutions are employed in binding synthetic textiles such as PVC, polyester, polypropylene, coated, filtering and technical fabrics.

Advantage:
Instead of needles, thread, glues or other adhesives, ultrasonic sewing equipment uses a patented rotary system, coupled with high-frequency vibrations, to bond synthetic or blended materials containing up to 40 percent natural fibers.
Resembling a traditional sewing machine, the ultrasonic sewing machine channels the ultrasonic vibrations between a horn and rotating wheel, producing a localized heat buildup which causes the synthetic fibers to soften and fuse. This creates a strong molecular bond that's impervious to moisture. Explains Alleman, "the resulting barrier seams are sealed, secure, ultra-reliable and soft-to-the-touch without the safety issues caused by stitch holes, glue gaps, fraying or unraveling."
