Ultrasonic Auto Welding Machine

Ultrasonic Auto Welding Machine

Ultrasonic Plastic Welding Function

This fully automatic machine completes the whole production process continuously without manual intervention, integrating four core functions:

1. Automatic elastic tape feeding

It delivers elastic tape at a steady speed, effectively avoiding twisting and deviation during conveying. Feeding length is flexibly adjustable for tapes of different widths, thicknesses and materials.

2. Automatic loop cutting

The built-in high-precision cutter performs loop-shaped cutting by preset parameters. With flat burr-free cuts and length tolerance within ±2mm per 100cm, it ensures uniform sizes for standardized batch production.

3. Automatic seamless ultrasonic bonding

Needle-free ultrasonic welding creates firm, smooth seamless joints. It retains maximum material elasticity, eliminates hard scratchy seams and thread breakage, and significantly improves garment wearing comfort.

4. Automatic finished product collecting

The automatic take-up mechanism collects and stacks finished products orderly, facilitating subsequent processing, reducing manual labor and maintaining a tidy production site.

Application

This ultrasonic auto welding machine is specially developed for elastic tape bonding and tubular seam welding of stretch garments, and is widely used in mass production of various tight-fitting and elastic textile products. Its specific application scenarios cover:

1. Underwear manufacturing It is suitable for waistband elastic welding of men’s and women’s briefs, boxers and seamless underwear, as well as shoulder strap splicing and edge bonding of intimate apparel. The seamless welding process replaces traditional needle and thread sewing, avoids friction and indentation caused by thread seams on the skin, and meets the high comfort requirements of close-fitting underwear.

2. Yoga wear and sportswear production It is used for elastic tape splicing at the waist and ankle cuffs of yoga pants, sports bras and fitness wear, as well as tubular seam bonding at side seams. The welded position maintains excellent stretch resilience, adapts to large-scale stretching during exercise, and is not easy to crack or deform, ensuring the durability and fitting effect of sportswear.

3. Dance costumes and performance wear processing It is applied to waist elastic welding, strap splicing and seamless joining of elastic fabrics for ballet costumes, dance jumpsuits and stage performance costumes. The flat weld seam will not rub the skin during long hours of dancing, while maintaining the overall aesthetic appearance of the costume, meeting the high standards of performance apparel.

4. Swimwear manufacturing It is used for waistband elastic welding, shoulder strap joining and side seam bonding of swimsuits and swimming trunks. The ultrasonic welded joint has good water resistance and salt corrosion resistance, and will not loosen or fall off due to long-term immersion in water, prolonging the service life of swimwear products.

5. Shapewear and tight-fitting garment production It is suitable for elastic band splicing at various parts of body shapers, waist trainers and tight-fitting shaping clothes, as well as edge closing processes. The seamless process reduces the pressure of seams on the body, improving wearing comfort while ensuring the shaping effect.
