The difference between metal label etching and laser processing of metal

　　Metal etching label processing refers to the use of chemical reactions or physical impacts to create a concave convex or hollow effect on metal materials. Etching processing involves removing the photosensitive ink in the area that needs to be etched after exposure plate making and development, and connecting it with a chemical solution in the etching equipment to achieve the effect of metal etching, forming hollow or concave convex patterns.

　　Laser processing is the use of laser to instantly melt metal and vaporize the physical denaturation, achieving the purpose of metal processing. By using laser to engrave characters on metal, the surface of the metal is smooth, and the handwriting is clear without wear and tear.

　　Both of these processing modes can achieve the effect of hollowing out, engraving, and forming concave and convex patterns on metal, but due to different processing methods, there are specific differences in the following points.

　　1. Laser signage can cause blackening and hardening of the processing area, while etching signage will not have these issues;

　　2. The cycle of processing metal by etching labels is shorter than that of laser cutting, and the processed graphics can also be changed by changing the drawings midway. However, laser processing requires modifying the design drawings, changing the design patterns, considering processing feasibility, etc., which is more cumbersome than etching label processing;

　　3. Etched label processing can simultaneously process different metal parts, such as metal nets with more mesh holes. Etched label processing can process multiple machined parts with different mesh holes, while laser processing cannot simultaneously process metal nets with different apertures;

　　4. Some components with thin materials and material characteristics can be affected by laser cutting, while the etching label processing process does not have this effect;
