Solutions for laser marking metals

There are many different methods for marking various metals. The process used may change based on the user's industries and applications.

Reliable and permanent

During machine construction, a large number of metal parts must be marked with UIDs, barcodes or 2D-codes for traceability. Often, serial numbers, time stamps and company logos are needed as well. These markings need to be resistant and capable of withstanding both mechanical stress and the weather. With a large amount of parts and workpieces, marking times become very important, which makes an efficient process like laser marking perfect for the task. Depending on the material you use, the necessary marking process could be either annealing, polishing or deep engraving. For instance, stainless steel can be laser marked with annealing so that there are no distinct indents in the surface. A large array of metals can be marked with Trotec laser marking systems, from soft metals like aluminum to extremely hard alloys.

Flexible and environmentally friendly

When it comes to marking and precision tools like turning, milling, and drilling supplies, high speed metal marking is especially helpful. Laser marking systems allow for the flexibility needed to mark even tiny and fine objects with markings that are extremely resilient and legible. Laser technology is both contact and chemical free, ensuring that no mechanical properties are changed and keeping erosion to a minimum. The laser beam is the most exhaustive tool for metals and alloys, making for a manufacturing process that is both economical and environmentally friendly. A large contrast can occur through a combination of both annealing and polishing. For instance, annealing the barcodes and text, then polishing the background. This allows for maximum legibility.

Durable and biocompatible

In medical engineering, there are a variety of metals including stainless steel, high alloy steels, titanium and titanium alloys that are used to make medical instruments and implants. These items require the highest quality for their markings and must be reproducible. Unlike other common processes, laser marking makes sure that the UDI codes and serial numbers that are mandatory by law in medical engineering are marked with no damage to the material's structure. Since there are no indents created in the material, no germs can settle inside and the marking will still be legible even after being cleaned thousands of times. The annealing process makes sure that the markings for traceability are both resilient and biocompatible.
