Laser Annealing Photo Etching

Laser annealing is a marking process where the laser heats the surface of the metal, causing an oxide layer to form beneath the surface. This creates a smooth, permanent mark without engraving into the material.

It is best suited to 316 grade stainless steel and certain titanium alloys. Other metals may not produce the same high-contrast results.

Unlike engraving or etching, laser annealing does not remove material from the surface. This makes it ideal for industries that require smooth, non-porous surfaces for hygiene or safety reasons.

Laser Annealing creates sharp and dark black lettering. It is a permanent marking

You can clearly see the laser annealed marking, but you cannot feel it.

No. The annealed mark is created within the surface of the metal and is highly resistant to fading, chemicals, and corrosion.

Popular uses include medical and surgical instruments, compliance plates, industrial parts, food-grade equipment, and any application requiring long-lasting, professional identification.

Yes. Our laser systems can produce fine detail, including logos, barcodes, serial numbers, and text, all with excellent clarity.
