Laser Marking machine Processing Technology Application

Laser marking is a marking method that uses a high-energy-density laser to locally illuminate a workpiece to raise the temperature of the surface layer, causing metamorphosis, melting, ablation, and evaporation, thereby leaving a permanent mark. Laser marking has two methods of engraving and mask imaging: mask mode marking uses a laser to image the stencil pattern onto the surface of the workpiece to ablate the marks. Engraving marking is a high-speed full-function marking system. After the laser beam is reflected by the two-dimensional optical scanning galvanometer, it is focused on the surface of the workpiece by the flat-field optical lens, and the material is vaporized according to the set trajectory under the control of the computer, and various characters, symbols and patterns can be produced. The character size can be from millimeters to the micron level,.The laser marking is permanent and not easy to be worn , which has special significance for the anti-counterfeiting of the product .
The laser marking machine has been used in the trademark model, numbering and other printed circuit boards of a large number of electronic components, integrated circuits. In recent years, the ultraviolet laser technology has developed rapidly. Due to the electronic energy band transition of the material under the action of ultraviolet laser, the bonding bond between the molecules is broken or weakened, thereby achieving the ablation processing, and the processing edge is very neat, so the laser marking technology is suddenly raised. In particular, it is valued by the microelectronics industry. Excimer laser marking is a new technology developed in recent years, which can achieve sub-micron marking and has been widely used in the field of microelectronics.
The high precision, high efficiency, and rapid processing methods of laser marking machines have saved many manufacturers from manufacturing and material resources, greatly improving production efficiency and producing finished products. The mature technology of laser marking machine not only benefits the industry, but also develops its skills.
The laser marking machines are most prominently processed in the following seven manufacturing industries:
1.Automotive machinery industry: bearings, steel jackets, piston rings, engines, machine tools, etc.;
2.Electronic communications industry: keyboards, electronic components, home appliances panels, optical cables, cables, etc.;
3.Hardware and equipment industry: tools, measuring tools, cutting tools, sanitary ware, cutlery, locks, knife and scissors, medical equipment, fitness equipment, stainless steel products, etc.;
4.Decorative buckle sign industry: buttons, luggage buckles, belt buckles, gold and silver jewelry, signs, badges, time cards, business cards, photographs, bags, belts, pens and pencil cases, collectors, artwork, etc.;
5.Instrument glasses industry: metal case, bottom, eyeglass frame, instrument panel, etc.;
6.Wood craft industry: wooden handicrafts, copy and form of calligraphy and painting, furniture and craft decoration;
Packaging bottle cap industry: tobacco, food, medicine, cosmetics and other internal and external packaging, metal caps, furniture decoration, decorative buckle signs, plastic products.
