Laser Marking Solutions
This is probably the most common method of laser marking, the laser removes one layer of material exposing another layer.
In most cases the result is a high contrast, crisp mark.
The pictures show anodized aluminum, painted plastic and a multi layered label.
Some material is removed, there is depth to the laser mark, possibly some raised material. The laser interacts strongly with the material. In some cases the laser engraving is later backfilled or used in a molding process.
The pictures show aluminum, gold and silicone.
Direct Laser Marking will change the color of materials creating contrast. Sometimes this happens naturally, some materials, especially plastics, have additives to enhance the mark.
Laser Annealing, no material is removed, the material just changes color.This is a very gentle, fine tuned interaction of the laser with the material.
Generally laser annealed parts are used in medical and other industries where oxydation needs to be avoided due to aggressive environments.
|Virtually all materials can be laser engraved. By choosing the right laser and the right laser settings, a large variety of different effects can be achieved. All laser marks are permanent.|
