Different ultrasonic cutting processes

The main role of the ultrasonic cutting process is to separate the connected components. The high frequency vibration per second can reduce the pressure on the item to be cut. This results in a neat and clean cutting surface. In practical applications, it is divided into two processes, separated welding and cutting.

Separation welding

Ultrasonic can cut thermoplastic multilayer textiles, non-woven materials or films into arbitrary shapes, and simultaneously weld along the cutting contour. The thermoplastic fiber content should be at least 20%. The cutting anvil with the corresponding cutting contour 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 area, thereby welding along the cutting edge.

Cut

The blade that is vibrated by ultrasonic waves quickly separates the items to be cut with little resistance, and no residue is generated. Ultrasound has been used in finished product cutting for many years. When cutting baked foods, energy bars, cheeses, pizzas and other materials, the vibrating (cold) cutting horn reduces the resistance during the cutting process and removes product residues that adhere. The result: a flat, re-cuttable surface without distortion or thermal damage to the product.

Application area

Synchronous edge cutting

Cutting and sealing are performed and completed simultaneously. Both ends of the welding fiber can be cut simultaneously within one micron, which is a clear advantage in the medical and filtration technology required for high quality.

Continuous cutting and sealing

The advantage of ultrasonic cutting and sealing technology is that it can quickly seal and cut woven and non-woven fabrics in continuous operation.

Cutting and welding

Flexible cutting of polymer and textile components must guarantee fast and accurate edge cutting. Ultrasonic processing is an ideal process in the automotive industry.
