We use an annealing process instead of stamping in order to eliminate the recesses and niches, eliminating opportunities for particle or water retention. In addition, this also eliminates the risk of a paper label becoming foreign matter.
Annealed markings are generated by using a laser which results in dark, high-contrast markings on a surface without material ablation. The use of ultrashort pulse lasers means that the heat-affected zone is extremely small, which does not affect the surface or cause a crevice. This process allows for various types of markings to be made, which remain easily legible, even after numerous cleanings and passivation cycles.
