UID marking was accomplished using a 20Watt Fiber Laser Marking System. A light etch was placed on the parts. A light etch was used due to the reflective nature of the metal, an etched mark would produce the best contrast. The code along with the text marked on the steel hub had a cycle time of 7.74 seconds. The UID code was marked at a height of 0.5” and along with the text, did not exceed the requested 1” marking zone. On the aluminum part, the 2D code could not be marked at a height of 0.5” so the code and text were scaled according to the available space. The code and text marked on the aluminum part had a cycle time of 4.58 seconds. Both codes read in the lab.
