Ultrasonic welding for nonwoven fabrics

Ultrasonics is created by converting electrical energy in the generator into mechanical vibrations in the converter and ultrasonic stack. This mechanical vibration travels through the ultrasonic stack, through the sonotrode and into the material. The standard frequencies used are between 20 and 35 kHz with an amplitude of 10 to 50 μm. The thermoplastic portion of the material is stimulated, heated up, and melted. The actual weld process is fast: Thanks to the use of rotating tools such as anvil drums, up to 800 m of nonwovens can be processed per minute. The anvil drum has an individual surface structure to focus the ultrasonic energy precisely. This allows for an exact weld through various processes.

The company is the world’s best Ultrasonic Embossing Machine(vi,zh-tw,ar) supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

A constant distance between the material being processed and the tools is important for optimal results, and this is guaranteed via the precise MICROGAP control technology. It ensures that the distance always remains consistent regardless of the thermal expansion of the tooling during the weld process.
