Laser-Marking.uk are capable of marking on many different types of materials.
The most common materials are metals and plastics, but our Trotec laser is capable of marking on ceramics and silicons.
Laser Marking and Engraving Types
- Engraving
- Etching
- Ablation
- Annealing
- Color Change
- Foaming
- Polish (Burnish)
Engraving
A process where material is actually removed or vaporized, then repeated to create depth in the material.
The measured depth for engraving is greater than 0.025mm.
Etching
A process where material is actually removed or vaporized, then repeated to create depth in the material.
The measured depth for etching is less than 0.025mm.
Ablation
The process of removing coatings like anodization, black oxide, zinc plating, masking, or insulation via the laser beam.
Annealing
The process by which the surface of a material is heated to just below its melting point in order to create oxide layers on the surface.
Colour Change
This mark type uses the energy of the laser beam to alter the molecular structure of the piece, making a visible change in the color of the underlying layer without damaging the surface of the material.
Foaming
This mark uses the energy of the laser beam to alter the molecular structure of the piece, making a visible change in the color of the substrate, without damaging the surface of the material. Foaming is similar to color changing, however the process actually raises the level of the material so it appears like a foam on the surface of the plastic.
Polishing
Polishing is a process where the laser’s intensity is reduced to ensure the lightest marking intensity possible. This creates a mirror-like oxidized surface layer without removing any actual surface material.We polish zinc plating to produce a visible mark without removing the protection of the zinc plating.
