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 matrices, production dates, logos, and more.
Laser marking equipment offers abrasion-proof, durable, fraud-protection. The laser marking process is fast, precise, contact-free, and extremely flexible and leaves a thermally and chemically resistant mark on any metal.
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 lasering. This method leads to a very robust, long-lasting, "burn-in" metal marking effect.
Fibre laser solutions offer direct marking of metals, resulting in gravures or an annealing effect, depending on the beam parameters and the metal used.
