Laser marking, electrolytic etching, embossing and other procedures compared the Laserbeschriftungbietet compared to other labelling systems some benefits, however the respective properties must (only solid-state lasers are regarded in this post) always in direct comparison to individuals, other technologies are considered. Also remember, that by the higher investment for laser systems in comparison to other technologies either a correspondingly high number of parts per year must be labeled, or the use of laser marking systems by other benefits should be justified. Comparison to needle stamping systems needle stamping systems are equipped with an oscillating pin, which can be moved in addition over conventional drives. A deepening/embossed into the workpiece, resulting in the oscillation (up / down movement of the needle). Texts and also, for example, marking can be generated by mechanical moving of the needle. Can usually only use this procedure metallic, robust materials (steel, Aluminiumetc.) are marked. The advantage of a marking laser compared to needle stamping systems first is that also plastics and other materials such as ceramics, and also fragile components can be labeled in addition to metals, it is not only limited to metal labels.
Still, you can labelled graphics such as, for example, company logo in high quality with the laser. There is also a less-invasive Beschriftungmoglich, meaning that comparatively structure changes can be avoided or minimized with the laser. Especially for the latter, the so-called Anlassbeschriftungan offers. When comparing the costs of operating, so wear-related replacement of embossing noble earlier or later maintenance of the drive unit are necessary when the needle embossing unit in addition to the regular. Modern, air cooled fiber-based Beschriftungslasersind here essentially maintenance-free and there is no downtime to go out. Another aspect is that of course a certain noise is expected to at the laser marking, this is usually significantly lower than at the stamping of the needle.
