Parts, Laser Marking
March 7, 2014
There are some obvious reasons to avoid permanently marking the parts you machine, including equipment cost and adding another step to a manufacturing process. These may be valid reasons if the parts you are making are low-cost commodity items or ones that have no possibility of causing a product failure. However, if the parts you produce fall outside of those parameters, you should give serious thought to encoding them with identifying information for 3 good reasons:
Clearly, indelibly marking critical parts makes good sense, and the method of choice is laser marking. Laser light can mark a wide range of materials without touching the part, so it’s an ideal choice for identifying parts of all shapes and sizes, even on hard to reach surfaces.
There are three laser marking methods: Engraving, in which the laser beam cuts into the material’s surface to create a marking. If desired, the manufacturer can also introduce colored oxides into the engraving to make the mark more noticeable. Ablation is often used to laser mark anodized aluminum or other coated metals by removing layers of colored coatings to reveal the base material. The third method, typically applied to ferrous metals and titanium, uses the laser to heat the area to be marked, which produces layers of oxide on the part’s surface, thus creating a contrasting color to the base metal.
