Description

We have more than 10 years of experience in welding technology. Having started with the welding production of personal protective equipment, we are now specialists in high-tech machine construction and ultrasonic welding components and software development with a huge application spectrum.

An ultrasonic rotary welding machine is a high-precision device designed to join materials, typically plastics or synthetic fabrics, using ultrasonic vibrations while employing a continuous rotary motion. This technology is often used in industries requiring seamless, strong, and efficient bonding, such as automotive, medical, and textile sectors.

How It Works:

1. Ultrasonic Vibrations:

• The machine generates high-frequency ultrasonic waves (usually 20–40 kHz) via a transducer.

• These vibrations are transferred to a horn (sonotrode) that contacts the fabric.

2. Heat Generation:

• The ultrasonic vibrations cause rapid molecular friction in the synthetic fibers, generating localized heat that melts the material.

3. Seam Formation:

• The fabric is pressed between the horn and a patterned roller or anvil.

• As the materials pass through, the ultrasonic energy creates a strong, clean, and fused seam.

Applications:

• Textile Industry:

• Seamless sewing of garments, such as lingerie, sportswear, or technical fabrics.

• Hemming, cutting, and sealing fabrics for curtains, banners, and other home textiles.

• Medical Industry:

• Producing nonwoven items like surgical gowns, face masks, and disposable medical wear.

• Packaging:

• Sealing synthetic bags or pouches for food, electronics, and consumer goods.

• Automotive:

• Bonding or sealing interior components, such as seat covers or airbags.

Advantages:

• No Thread or Needle:

• Eliminates the need for consumables like thread, reducing costs and maintenance.

• Fast and Efficient:

• Processes materials quickly and seamlessly without requiring manual adjustments.

• Clean and Precise:

• Produces clean seams with no fraying, making it ideal for delicate or high-performance fabrics.

• Eco-Friendly:

• Reduces waste by eliminating the need for adhesives or other consumables.

• Hygienic:

• Suitable for medical and food packaging applications due to the clean bonding process.
