The best engraving processes for metal
In the world of industrial marking, choosing the right metal engraving technique is crucial. For traceability, identification or aesthetics, each method offers specific advantages.
We’ll look at the different types of engraving according to marking technologies, and the professional equipment to choose for high-quality results.
Dot peen marking
The only type of dot peen marking technology is deep engraving. This involves engraving the motif directly into the metal using a tungsten “stylus” directly on the surface of the material. This technique is often used in the mechanical industry, in metallurgy, aeronautics and automobiles for example.
Despite the fact that dot peen offers only one type of marking, this deep engraving is in fact the advantage of choosing dot peen technology. Indeed, the fact of engraving fairly deep parts makes the information reliable, as it is resistant to wear and falsification. It is often used for component traceability in the above-mentioned sectors.
The different types of laser engraving
Laser engraving is a highly precise process, particularly suited to designs requiring a detailed, delicate finish. Unlike dot peen solutions, laser marking stations offer greater freedom in terms of marking rendering. Thanks to numerous parameters, it is possible to adapt the engraving rendering to suit your needs and the material to be marked, such as stainless steel, for example.
Here are a few examples:
- Annealed marking
- Foam marking
- Material removal marking
- Bleach marking

Which professional machine should I use to mark metal?
For effective, long-lasting marking, the use of professional machines is essential. Technomark Marking offers a range of solutions adapted to different needs: laser and dot peen marking machines, taking into account your use (portable, station and workbench or integrated).
This equipment offers precision, speed and flexibility, enabling you to engrave alphanumeric sequences, serial numbers, logos and various codes such as datamatrix or QR codes.
How do I engrave metal?
Engraving on metal requires specific steps to guarantee optimal results. Here’s a list of the key steps:
- Choose the appropriate engraving technology according to the desired effect.
- Prepare and select the marking surface.
- Set up the marking machine (force and power, repetition, speed, etc.).
- Pay particular attention to positioning the part in relation to the marking.
The precise engraving offered by laser marking and dot peen reduces the need for excessive rejects. This precision helps to preserve natural resources by avoiding unnecessary waste of materials. Companies adopting these technologies demonstrate a commitment to sustainability and environmental responsibility.
