Which process is better, hardware etching or hardware laser engraving?

Hardware etching and laser engraving are two common metal surface treatment processes. As for which process is good, it depends on the specific situation and cannot be compared and evaluated in general. Both have their own characteristics and advantages and disadvantages.

1, compared with laser engraving, the etching process is complicated, requiring pretreatment, plate making, etching, painting and other processes, while laser etching is much simpler.

2. In terms of production efficiency, etching can be carried out simultaneously in batches. Laser engraving can only be carried out one by one, which is suitable for small batches.

3, the etching depth is guaranteed, and it is suitable for touch-up paint after etching. Laser engraving is relatively shallow, which is not suitable for painting after engraving, and is suitable for marking hardware and other businesses.

4. In terms of fineness, the edge uniformity of etched lines is better than that of laser engraving, which is suitable for some workpieces that are not very strict with lines, such as photo engraving.

5. After etching, it has little effect on the internal lattice structure of metal, but laser will have a certain effect on the microstructure of metal.
