Laser etching also allows you to mark the bare aluminum before the anodizing process.
Laser etched anodized aluminum.
With this process you can mark anodized aluminum on the surface of the anodized layer.
Laser etching anodized aluminum is one of the most common applications of laser engraving machines around the world with its popularity owing to the unique durability and aesthetics of the material and the bright high contrast markings produced by a high quality laser engraving machine.
The laser beam only removes the anodized layer from the aluminum piece resulting in high quality marks.
Anodized aluminum results in a stunning final product.
Another important point when engraving anodized aluminium is that the engraving must be done fast.
Therefore the engraving is a bright silver color in contrast to the color on the surface of the tag.
There are two types of lasers used for etching or scribing laser engraving metal surfaces.
This allows you to keep the material s high resistance to corrosion and abrasive wear.
Laser marking anodized aluminum is a selective process known as laser etching.
I live near a diy workshop called techshop they have 1m worth of equipment that i can get access to for about 100 a month.
Another advantage of anodized aluminum tags is the high contrast between the surface color and the engraving.
Whether etching images text or logos co2 engraving will leave a contrasting white color on the sheet being processed.
To laser mark aluminum you should use a fiber laser system.
Able to engrave into dozens of materials including some softer metals including anodized aluminum.
One piece of equipment they have i.
Anodized aluminum is an outstanding material used for laser etching.
The color of the mark is highly contrasted between the anodized aluminum and the laser induced mark.
When engraving onto anodized aluminum it is important that the vector graphic is produced using a rgb colour palette and that the engraving colour is black rgb value 0 0 0.
Laser etching anodized aluminum.
This includes anodized aluminum.
This type of laser is capable of scribing right through the anodic coating to the bare substrate underneath.
You can even engrave into jade veneer and cork.
Depending on the color of the anodized aluminum itself a fiber marking laser can efficiently produce darker marks while a co2 marking system can produce bright engraving with contrast.
The anodized coating is heated by laser energy and evaporates requiring little to no cleanup.
Anodized aluminum can be produced in a spectrum of colors and shapes and with laser etched markings that.
Anodized aluminum tags can be deep rotary engraved in which the engraving cutter cuts through the anodized layer and into the core aluminum.
Laser machines are an ideal technology for marking and engraving on anodized aluminum and can be used with both co2 and fiber systems.
There are some metals you can now engrave with this laser engraver.
This will give the most contrast when engraved.
This instructable will show you how to use a laser cutter to etch anodized aluminum.
You can thus.
