Laser Marking on Metals in the Industrial Sector

Lasers have worked well over the years, especially when it comes to marking on metal. Not only soft metals such as aluminum, but very hard steels or alloys can also be marked accurately, clearly, and quickly using a laser. With certain metals such as steel alloys it is also possible to apply corrosion resistant marks without damaging the surface structure.

Products made of metal are laser marked in a variety of industries from marking industrially manufactured series products for traceability to personalizing promotional items with logos or names.

Metal marking application with laser marking

Laser applications in metal marking are typically used to mark products with features and traceability codes. These applications can be found in the electronics and electrical industries, mechanical engineering, tool manufacturing, in sheet metal processing, medical technology, promotional materials, jewelry, and in the automotive industry.

How does laser marking works?

Laser marking or laser marking is an invisible mark that does not affect the surface of the material where no material is removed during the marking process. By heating the metal, of course, there will be a change in color. For example, the color of stainless steel changes at a temperature between 200 ° C and 300 ° C. Different colors can be achieved at different temperatures.

Usually, this aims to get a perfect marking process. The perfect marking is possible on stainless steel and titanium, but not on other metals. Marking is also possible on ferrous alloys.

Conclusion

Laser marking using a laser machine is a precise and clean form of metal processing. Markings such as serial numbers, data matrix codes and logos can be added to products and components in the highest resolution possible. Laser marking is done with a laser and requires no pre- or post-processing. Duta Laserindo Metal ensures permanent, acid, chemical and corrosion resistant laser marking without damaging metal surfaces.
