The marking effect of 355nm UV laser on ceramic products is like natural carving

Ceramics are widely used, tableware ceramics, ceramic sanitary wares, ceramic construction supplies, etc., are ubiquitous in our daily lives. Marking LOGO on ceramics and engraving personalized logos have become the development direction of high-end ceramic decoration in the future.

The traditional methods of marking ceramics include etching, engraving, grinding, or applying color glaze, colorant or decals for secondary sintering. These marking methods will cause damage to ceramic products, especially etching, engraving and grinding. When applying color glazes, colorants or decals, they must be sintered again, which makes the marking process more complicated and wastes energy. Increased production costs. Therefore, a new ceramic marking method is needed.

 Ultraviolet laser marking is a non-contact high-energy fast sintering technology. Due to the low-impact characteristics of ultravio
