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

Applications

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.
