Introduction:

Ultrasonic seamless stitching is an advanced technology that joins synthetic materials and blends to create continuous and impermeable seams. Fabrics can be 100% thermoplastic synthetic fibers or blended fibers with a natural fiber content of up to 40%. The ultrasonic sewing machine uses a disc-type sonotrode for roll welding, which cleverly converts the longitudinal vibration of the transducer, and the disc-type sonotrode radiates 360° outward radial vibration in the diameter direction to achieve seamless stitching of the material. Ultrasonic seamless stitching plays an increasingly important role in various industries, meanwhile ultrasonic seamless stitching technology also completely solves the problem that the movement direction of ultrasonic welding head and the movement direction of the cloth are inconsistent and out of synchronization, which will replace ordinary sewing machines to a large extent.

Application:

Ultrasonic sewing machine is playing an increasingly important role in various industries, mainly including:
1. The clothing industry.
For clothing manufacturers, ultrasonic sewing machines are very fast, clean, and economical. Ultrasound can be used for various artificial fabrics and plastics, and natural fabrics can also use a minimum content of at least 60% thermoplastic. Ultrasonic seamless stitching technology provides beautiful and smooth seams for lightweight underwear and sportswear fabrics, and is also very suitable for connecting with Velcro and polyester straps. Fabric seams can be completely flat on the body with adhesive tape, which is four times stronger than sewn seams.
2. Medical industry.
Ultrasonic sewing machines can produce commonly used clothing including protective clothing, disposable hospital surgical clothing, shoe covers, masks, baby warm clothing, filters, bags, curtains, sails, and mesh stitching. Ultrasonic seams are beneficial in the manufacturing of these items, as sealing edges and seams without suturing holes will not penetrate chemicals, liquids, blood borne pathogens or other particles.
3. Outdoor products industry.
Due to the airtightness of ultrasonic stitching, it can form strong joints and reduce the formation of holes. Therefore, this technology is also used to manufacture outdoor products such as sails and parachutes. This technology is widely used in clothing for skiing, cycling, sailing, mountaineering, rowing, hiking, and other sports, as well as waterproof backpacks, outdoor tents, military equipment, and so on.

Advantage:

1. 1. High stability. The rotation of the welding wheel and the pressure wheel is completely synchronized during ultrasonic wireless stitching, there is no speed and angle difference, no stretching, twisting or deformation of the cloth, and the accuracy is extremely high. Thanks to the hot melt effect, there is no need for needles and threads, resulting in increased water resistance, lighter weight and easier folding. 2. Welding and sealing synchronization. The ultrasonic wireless stitching equipment is not only suitable for continuous stitching, but also for cutting textiles while welding, and realizing automatic edge banding. 3. No thermal radiation. When ultrasonic stitching, energy penetrates the material layer for welding, there is no thermal radiation, and during the continuous stitching process, heat is not transferred to the product, which is particularly beneficial for the packaging of heat-sensitive products. 4. The weld seam is controllable. The cloth is under the traction of the welding wheel and the pressure wheel, passing through it, and the cloth is welded using ultrasonic waves, and the size and embossing of the weld can be changed by replacing the pressure wheel, which is more flexible and convenient to use. 5. Wide range of applications. All thermoplastic (heated and softened) fabrics, special tapes, films can be welded using ultrasonic wireless stitching equipment, and rollers made of hardened steel for long service life.
