3d deep engraving 1

The metal laser marking machine exposes the deep material through the evaporation of the surface material, or causes the chemical physics of the surface material through the change of light energy and "engraving" marking, or through the light burning part of the substance, showing the need to etch graphics and text. Most metal laser marking machines can be used for marking, but according to the desired effect, it can be divided into shallow engraving and deep engraving.


The marking of metal materials is mostly shallow engraving. Lines above microns are ablated on the metal surface. The engraving depth is 5~25 microns, and the width can vary from a few microns to tens of microns. Due to the laser, the color and reflection of these lines are different from the original, causing the contrast effect of the human eye and the eye to form a marking effect. Through the metal laser marking machine, the surface marking number, pattern, trademark, barcode, two-dimensional code, etc. of metal materials can be easily realized, which is widely used in permanent marking on the surface of various tools and spare parts.


The depth of deep engraving is usually deeper and depends on the material, the power of the laser and the engraving time. Generally speaking, the depth of engraving is related to the absorption of the laser by the engraving material, and the power of the laser is related to the time factor of the laser acting on the engraving material. Deep carving usually takes a long time. On the surface of various gold plastic materials, deep and shallow engraving can be carried out, such as engraving logo codes, company logos and more complex images. Deep carving is mainly used for carving abrasive tools, seals, etc.
