what is anodized aluminum? Colored anodized aluminum promotional products undergo a process known as “anodization”, which thickens the natural oxide layer of the carabiner. It results in a heavier, stronger oxidized layer of controlled thickness with the hardness similar to that of a ruby or sapphire. This anodized coating is extremely desirable for products such as engraved carabiner. Due to its increasing corrosion resistance, durability and wear resistance, ability to be colored via dying and sharply laser engraveing. These anodizing coatings can be clear or colored, and they actually integrate with the surface of the aluminum, getting an extremely durable, shiny and wonderfully smooth layer on the carabiner.
Laser engraving the surface of anodized aluminum
This anodized layer also responds exceptionally well to laser engraving. The laser could etch or carve your design literally right through the anodized surface, and exposing the aluminum underneath. So when you see the printing, you should look at the revealed aluminum under the anodized surface, which has been precisely removed.
When it comes to laser engraving on anodized aluminum, not all systems are equal. For instance, the much slower CO2 system produces marks of varying quality depending on the product color (anodized coating). Quality is defined in terms of brightness of the mark: the brighter and sharper the better. A high quality laser engraved mark appears bright white and crisp no matter what the color of the material.
Logo printing
Quality laser engraving produces a permanent mark that simply can’t rub off. Laser engraving is a superior marking process as comparing to conventional silk screen printing and pad printing which wears off over time. Laser engraved carabiner from Kimjee® will keep your name, logo or message visible at all times — a clear advantage for you and your products!
