20Khz Ultrasonic Sewing Machine with Rotary Anvils & Rotary Horn for Lamination And Edge Sealing

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 vibrations (usually between 20–40 kHz) via a transducer.

• These vibrations are transmitted to a rotary horn (sonotrode), which rotates continuously during operation.

2. Heat Generation:

• The ultrasonic energy causes friction at the interface of the materials, generating heat that melts and bonds them at a molecular level.

3. Rotary Motion:

• Unlike traditional ultrasonic welding, the horn rotates, enabling continuous or curved welding, making it suitable for long seams or circular designs.

4. Welding Process:

• Materials are fed between the rotating horn and anvil (counterpart), and the ultrasonic vibrations are applied precisely to the welding area.

• The process can simultaneously weld, cut, and seal, depending on the application.

Applications:

• Automotive Industry:

• Bonding components like air filters, interior trims, or upholstery.

• Medical Devices:

• Welding IV bags, blood filters, or other disposable medical components.

• Textile Industry:

• Sealing nonwoven fabrics for products like hygiene pads, surgical gowns, or geotextiles.

• Packaging:

• Creating airtight seals for products in food, electronics, or consumer goods packaging.
