Ultrasonic Digital Type 40khz Fabric Cutting Machine For Nonwoven Sealing

The ultrasonic Cut&Seal process is used everywhere, where it is important to seal edges as they are being cut or in order to make a process more efficient by combining the two steps and avoiding subsequent punching. For example, in the packaging industry, the sonotrode table is used, with which blisters, trays or cups can be sealed and punched out in one step.
Cut&Seal is used in the textile industry when welding elastic and non-elastic thermoplastic textiles continuously using the roll seam module or intermittently using upright sonotrodes. The main advantage of ultrasonic Cut&Seal is that the edges are already sealed during cutting, thus preventing subsequent fraying.

· The whole of ultrasonic cutting edge banding machine is composed of ultrasonic generator (drive power) and ultrasonic host (cutting part).
· Through ultrasonic high-frequency vibration, the fabric to be processed is densely bonded first, and the rear blade is followed by the dense pattern to synchronously slit or trim the fabric.
· The ultrasonic host is simply installed on the knitting equipment, which can realize the cutting of woven fabrics and ensure that the fabrics are not scattered, hardened, smooth and beautiful; the equipment is safe and reliable in operation.
· Mainly used in the processing and weaving industry of chemical fiber textiles, geotextiles, woven fabrics, plastic films and non-woven fabrics; the woven fabrics contain thermoplastic materials such as polypropylene and polyethylene.

When the ultrasonic cutting knife performs ultrasonic vibration, the friction resistance is very small, and the material to be cut is not easy to stick to the blade. It has obvious cutting effect on frozen, viscous and elastic materials. It is especially effective for cutting food, rubber or objects that are inconvenient to apply pressure.

At the same time of cutting, the cutting part has fusion function, and the cutting part can be sealed, which can prevent the loosening of the cut material (such as textile material flash).
