Laser engraving creates patterns, combined with chemical etching to create depth. Depending on the texture effect, multiple laser engraving and chemical etching can be performed until the texture effect is achieved. This work can be applied to any curved surface to enrich, refine, and improve the texture of chemical etching.

This process can produce more patterns, even complex surfaces can be processed, breaking the limitations of laser engraving, improving production efficiency, greatly reducing production time, and making patterns more detailed and three-dimensional.
