After the laser process, the residues of the paste or spray must be washed off. For this operation, a lot of energy is required; thus, the laser must be moved at an appropriately low speed. On some metals, high contrast can be achieved by using this process, while it should be noted that not all metals are suitable for paste or spray marking. The necessary pastes or sprays are very expensive, and the whole process is very time-consuming. Metal can be directly marked with a fiber laser. A distinction is made between engraving, annealing marking, and coating ablation. The devices of the Speedy flexx series are equipped with a CO2 and a fiber laser. Use both laser sources in a single job without having to manually change the laser source, the lenses or the focus. The patented JobControl® laser software makes it possible: Simply assign the desired laser source to each color of the graphic.
