Laser marking metal

Precision engraving

By means of laser engraving it is possible to make detailed markings in a metal surface. These engravings are applied by means of fiber engraving laser machines. These types of engraving machines are capable of creating fine details on metals.


Properties laser marking

  • High precision – detailed marking
    • Images (JPEG/PNG/…) can be engraved by ‘bitmap’.
    • Fiber laser machines are used.
  • High speed
  • Rich in contrast
  • Contactless process
    • Object doesn’t have to be clamped so material is not damaged (scratches).


Engravable/markable materials

At Raytech we usually recommend engraving on aluminum or stainless steel in addition to real engraving material, other metals are a lot more difficult.

Suitable metals:

  • Aluminium
  • Stainless steel (SS)
  • Steel
  • Chrome
  • Zinc
  • Gold
  • Silver
  • Titanium
  • Brass
  • Platinum
  • Hardened metals
  • Copper alloys
  • Coated metals

Others, non-metals

  • Acrylic
  • Rubber
  • Glass
  • Wood
  • MDF
  • Bamboo
  • Horn
  • Leather
  • Textile
  • Cardboard



Given the durability of a marking made by laser, it’s used for a large number of applications:

  • Serial numbers to identify mass productions
  • Apply QR codes – barcodes
  • Marking of machinery instructions on instructions plates
  • Apply logo or image to objects or promotional gifts
  • Signage boards
  • Decorative objects

Make a depth slot – color shades

By laser engraving, it’s possible to make a slot at a relatively constant depth. This depth control is mainly determined by the speed – frequency ratio.
This ratio also influences the color that occurs during marking. It’s possible to obtain different shades depending on the parameters.
