Laser marking metals such as anodized aluminum, stainless steel, brass, and others is a very common industrial application, allowing users in a range of industries to permanently mark their parts and equipment with serial numbers, barcodes, data matrixes, production dates, logos, and more.
Laser marking equipment offers abrasion-proof, durable, fraud-protected, and thermally- and chemically-resistant markings for any type of metal. The laser marking process is fast, precise, contact-free, and extremely flexible.
Trotec offers a range of CO2 and Fiber laser marking systems for metals:
CO2 laser technology is ideal for metals such as anodized aluminium, and on coated or refined metal surfaces. CO2 lasers can also achieve annealing effects using a high output, and can be used to create inscriptions on bare metals by applying a special spray to the metal surface prior to irradiation. This method leads to a very robust, long-lasting, "burn-in" metal marking effect. CO2 solutions
Fiber laser solutions offer direct marking of metals, resulting in gravures or merely an annealing effect, depending on the beam parameters and the used material.
