Laser Marking Adds A Touch Of Color To The Dull Metal
Aug 30, 2018

As one of the most important inventions of human beings in the 20th century, laser technology has penetrated into all aspects of industry, agriculture, military, medicine and society. With its unique processing advantages, it promotes the progress of human society. Laser marking equipment is undoubtedly Currently the most widely used category.

Laser marking is simply the use of laser marking equipment to mark objects. Compared with traditional marking methods such as stickers and inkjet, the marking of laser marking equipment is clearer and permanently erasable, so the application The scope is increasingly wide, in addition to the daily necessities we often see, laser marking can also bring us a lot of surprises.

The basic principle of stainless steel color marking is to use a high energy density laser heat source to act on the stainless steel material to form a colored oxide on the surface, or to form a colorless transparent oxide film, which is presented by the optical interference effect of the film. Colored effect. Moreover, by controlling the laser energy and parameters, different colors exhibited by different thickness oxide layers are realized, and even color gradient marking is realized.

3D marking easily conquers surface markers

In the traditional plane marking machine, the workpieces must be placed on the same plane, and the processing surfaces must also be on the same plane, in order to realize the marking of one molding, and the surface marking cannot be completed. At the same time, traditional 2D marking has inherent defects in deep surface engraving. As the laser focus moves up during the engraving process, the laser energy acting on the actual surface of the object will drop sharply, which seriously affects the effect and efficiency of deep carving.

The 3D laser marking device can get rid of the limitation of the shape of the object and dance on the uneven surface to create a three-dimensional marking effect. Compared with the traditional 2D laser marking, the 3D laser marking equipment has greatly reduced the surface flatness requirement of the processed object. In the process of deep carving, the effect is ensured, the efficiency is improved, and the processing effect is more abundant. Colorful, more creative processing techniques came into being.
