This operation requires a lot of laser energy, and the beam needs to be moved at a very low speed. Some metals can have a high-contrast finish by using this method, but it should be noted that not all metals are suitable for paste/spray marking – always do your research before committing to a material! The pastes and sprays are also very expensive, and the entire process is very time consuming.
However, metals can be marked directly with a fiber laser, and a clear distinction is made between engraving, annealing marking and coating ablation. The machines in the Speedy Flexx series are all equipped with a CO2 laser as well as a Fiber laser, so you can use both sources on a single job without having to manually change the settings (laser source, lenses, focus). JobControl® laser software makes this easy: just assign the preferred laser source to each colour of the graphic and you’re ready to go!
