How 35kHz ultrasonic sewing machine makes PVC achieve sealing effect

Ultrasonic sewing machine is an efficient sewing and embossing equipment. It is mainly used for seaming, welding, fusion cutting and embossing of synthetic fiber fabrics. The processed products have the characteristics of good water tightness, high production efficiency, no needle and thread accessories, smooth fusion cutting surface without burrs, and good hand feeling. Ultrasonic sewing machines are widely used in clothing, toys, food, environmentally friendly non-woven bags, masks (cup masks, flat masks, three-dimensional masks, etc.) and other industries.

working principle
Using high-frequency oscillation, the sound wave is transmitted from the welding head to the welding surface of the workpiece, and the molecules of the workpiece are rubbed instantly to reach the melting point of the plastic, thereby completing the rapid dissolution of the solid material and completing the welding.

Applicable material
Chemical synthetic fiber fabrics, or chemical fiber blended fabrics, chemical films (containing more than 30% chemical fibers), can be processed into required products, such as Nylon fabrics, needlework fabrics, non-woven fabrics, T/R fabrics, Tetralong fabrics (Polyester cloth), multi-layer cloth, and various laminated surface-covered cloth-like film papers are applicable.

we can see the the PVC airbag has good pressure resistance and ood airtightness, if you have such machine, making such airbag will be very easily.
