The main function of the ultrasonic cutting process is to split the connected components. The pressure on the item to be cut can be reduced by the large frequency vibration per second. This makes it possible to form a neat and clean cutting surface. In practice, it is divided into two processes, separate welding and cutting.
Ultrasonic waves can be used to cut thermoplastic multilayer textiles, nonwoven materials or films into any shape while welding along the cutting profile. The thermoplastic fiber content should be at least 20%. The anvil with the corresponding cutting profile is cut by the vibration generated by the ultrasonic system. At the same time, the vibration attenuation causes heat to be generated in the cutting zone to weld along the cutting edge.
The blade vibrating by ultrasonic waves quickly and accurately separates the articles to be cut with minimum resistance without generating residue. Ultrasound has been used in finished products for many years. Vibrating (cold) cutting horns reduce drag during cutting and remove adhering product debris when cutting materials such as baked goods, energy bars, cheese, pizza, and more. The result: a cleavable flat surface is formed without deformation or thermal damage to the product.
