Product Detail

Product Introduction

Laser marking or engraving have 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 many materials, metals, plastics or organic. Laser marking, without contact with the part to be marked, and capable of finely and aesthetically reproducing complex shapes (texts, logos, photos, bar codes or 2D codes) offers great flexibility of use and does not require any consumable.

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 used little laser markers with wavelengths in the visible or in the ultra violet. 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 by coloring material in addition to the pigments possibly present in it. Marking on transparent materials is also possible with lasers of the appropriate wavelength, usually UV or CO2. On organic materials, laser marking generally acts thermally. A laser marker will also be used on all these materials for marking by ablation of a layer or of a surface treatment of the part to be marked.

The autofocus function is different to the motorized focus. The motorized z axis also need to press the “up” & “down” button to adjust the focus, but autofocus will find the correct focus by itself. Because it has a sensor to sensor the objects, we set the focus length already. You just need to put the object on the worktable, press “Auto” button, then it will adjust the focus length by itself.


It used for various products such as gold & silver jewellery, sanitary ware, food packing, tobacco products, medicine packing, medical apparatus and instruments, watches & glassware, auto accessories, electronic hardware and so on.
