What is the difference between ultrasonic cutting of nonwoven fabrics and laser cutting?
Principles of ultrasonic cutting and laser cutting of non-woven fabrics1. Ultrasonic cutting of non-woven fabrics
Ultrasonic cutting of non-woven fabrics is a method of cutting non-woven fabrics using high-frequency vibration waves and cutting blades. During the cutting process, the ultrasonic vibration frequency is as high as 20KHz or more, which transfers energy to the non-woven fabric, causing it to produce elastic deformation, thereby forming cracks and finally completing the cutting.
2. Laser cutting
Laser cutting uses a high-power laser beam to directly heat and evaporate the material to achieve the purpose of cutting. The energy density of the laser beam is very high, which can penetrate the material and generate instantaneous high temperature inside it, causing it to instantly sublimate into gas, thereby forming cracks and completing the cutting.
Application scope and advantages and disadvantages of ultrasonic cutting and laser cutting of non-woven fabrics
1. Ultrasonic cutting of non-woven fabrics
Ultrasonic cutting of non-woven fabrics is suitable for relatively soft materials, such as various film materials, nylon, polyester, polyamide, polyimide and carbon fiber. Its advantages are: fast cutting speed, high precision, good verticality of cutting surface, surface is not affected by heat, no burrs and segment surface, and suitable for large area cutting and multi-layer cutting.
2. Laser cutting
Laser cutting is suitable for various organic, metal, glass, ceramic and other high hardness materials. Its advantages are: high cutting precision, smooth incision, smooth segment surface, controllable cutting size, and can cut or punch some special shapes.
Application and effect of ultrasonic cutting and laser cutting of non-woven fabrics in non-woven fabric cutting
1. Application and effect of ultrasonic cutting of non-woven fabrics
Ultrasonic cutting of non-woven fabrics is one of the mainstream methods for cutting dust-free fabrics at present, because the material of non-woven fabrics is relatively soft and has high requirements for cutting accuracy. This method is widely used in the production and manufacturing of non-woven fabrics, clothing textiles, automobile manufacturing and other fields. Its cutting effect is smooth, no burrs, small color difference, especially suitable for cutting and customization of some special materials, and has been widely recognized.
2. Application and effect of laser cutting
Laser cutting is relatively less used in the field of non-woven fabric cutting, mainly because laser cutting is suitable for materials with higher hardness, while non-woven fabrics are relatively soft. However, for some film materials and non-woven fabrics of special shapes, laser cutting is also a feasible method. Due to its fast speed, high efficiency and high cutting accuracy, laser cutting has been widely used in some special non-woven fabric processing industries.
