What is ultrasonic seamless sewing?

The ultrasonic seamless suturing system is composed of a 35KHz ultrasonic transducer, a variable amplitude rod (fixed function), a circular welding head, and a matching specialized CNC power supply combination. The ultrasonic numerical control power supply converts the mains power into 35KHz high-frequency high-voltage AC power and supplies it to the ultrasonic transducer. Ultrasonic transducers convert electrical energy into mechanical energy (ultrasound), which generates amplitude when the transducer moves longitudinally and is then transmitted to the circular welding head through a variable amplitude rod. So that the circular welding head can be welded, equipped with a frame, pressure wheels, and auxiliary structures and control components, making it a complete ultrasonic cutting sewing machine.

Ultrasonic seamless sewing technology is the latest technological achievement in the world for sewing and cutting fabrics. Fansuoneng Company closely follows the latest scientific research achievements abroad and develops the core of ultrasonic seamless sewing machines. This is the core component of the ultrasonic seamless sewing machine, which completely solves the inherent problem of the original ultrasonic longitudinal vibration technology, that is, the movement direction of the ultrasonic welding head is inconsistent with the movement direction of the fabric. The accuracy of ultrasonic fabric sewing has been greatly improved, which makes the widespread application of ultrasonic technology in the field of clothing sewing possible. Ultrasonic seamless sewing has the characteristics of fast welding speed, high strength, beautiful welds, good sealing performance, low energy consumption, and easy operation, which is the development direction of sewing machines.

Traditional sewing machines sew two pieces of fabric together using a needle and thread. During the threading process, not only is the fabric punctured, but there is no bonding between the fabrics, and they are only tied together with a thin thread. This way, the fabric is easily torn and the thread is also prone to breakage. Thermoplastic fabrics can be sewn together by hot air welding, without the need for needle and thread, but the welding temperature is difficult to control and the welding speed is slow.

The ultrasonic seamless stitching system can sew most thermoplastic fabrics. Compared to ordinary needle and thread stitching, ultrasonic stitching does not require needle and thread, has high stitching strength, good sealing, and fast stitching speed. And the ultrasonic seamless sewing system completely solves the problem of inconsistency and asynchrony between the movement direction of the ultrasonic welding head and the movement direction of the fabric, which will greatly replace ordinary sewing machines.
