Details introduction

Laser marking or engraving has been widely used in industry for several decades for identification or traceability needs. It constitutes an advantageous industrial alternative to many mechanical, thermal, or inking processes on various materials, including metals, plastics, or organics. Laser marking is capable of finely and aesthetically reproducing complex shapes (texts, logos, photos, bar codes, or 2D codes). It offers great flexibility of use and does not require any consumables.
Almost any material can be marked with a laser source as long as the correct wavelength is used. Infrared (IR) is most commonly used (1.06 microns and 10.6 microns) on most materials. We also use laser markers with wavelengths in the visible or in the ultraviolet range. On metals, whether by etching or surface annealing, it provides durability and resistance to acids and corrosion.


On plastics, the laser acts by foaming or coloring the material, in addition to any pigments that may be present. Marking on transparent materials is also possible with lasers of the appropriate wavelength, usually UV or CO2. On organic materials, laser marking generally occurs thermally. A laser marker can also be used on all these materials for marking by ablating a layer or treating the surface of the part to be marked.
The autofocus function is different from the motorized focus. The motorized z-axis also needs to press the "up" and "down" buttons to adjust the focus, but autofocus will find the correct focus by itself. Because it has a sensor, we have already set the focus length. You just need to place the object on the worktable, press the "Auto" button, and it will adjust the focus length by itself.
