is the use of laser beam light energy to cause chemical and physical changes on the surface material to engrave traces, or light energy to burn part of the material, showing the required etching graphics, text; according to the different engraving methods can be divided into Lattice engraving and vector cutting.
"Heat processing" laser beam (it is a concentrated energy flow) with a higher energy density irradiates the surface of the material to be processed. The surface of the material absorbs the laser energy and produces a thermal excitation process in the irradiated area, thereby making the surface of the material (or coating) The temperature of the layer) rises, causing phenomena such as metamorphosis, melting, ablation, and evaporation.
Dot matrix engraving resembles high-definition dot matrix printing. The laser head swings left and right to engrave a line composed of a series of dots each time, and then the laser head moves up and down to engrave multiple lines at the same time, and finally constitutes a full-page image or text. The scanned graphics, text and vectorized graphics can all be engraved by dot matrix.
