1. No edge sealing (cold cutting): it is mainly cut directly by electric scissors. This cutting method is easy to produce lint on the edge, and it cannot be cleaned after cutting. In the process of wiping with dust-free cloth, a large number of cloth chips will be generated on the edge, which has no cleanliness. Generally, it is not recommended to use.
2. Laser cutting: through the instantaneous high-temperature melting of the laser, the edge sealing is good and there is no hair chip. After cutting, net spraying and cleaning can be done, so that the dust-free cloth can reach a higher dust-free standard The disadvantage is that the edge will be slightly hard because it is broken. There is generally no problem with paying attention to points during wiping. At present, 75% of the market uses this kind of edge sealing method.
3. Ultrasonic edge banding: through the vibration generated by the ultrasonic vibration unit (vibrator) (converting electrical energy into mechanical energy), heat is transferred through horn (welding head), and then the fabric is crushed by the cutter. This edge banding is one of the current cutting methods for dust-free cloth. The edge banding effect is good and the edge will not be hard. However, this cutting method costs too much, so only a small number of powerful enterprises will choose it. The market share is about 15%.
