Process Date: July 2002We were able to create this nicely contrasting barcode (5mm high) using our 25W laser. The ten character barcode was marked at a speed of 100 inches per second with a resolution of 425 dpi resulting in a cycle time of 3.8 seconds.Using our 10W laser, the same code can be made at a speed of 10 inches per second with a cycle time of 17.9 seconds.
The major advantage of the CO2 wavelength vs. the shorter YAG wavelength is that the anodized coating is left intact.The CO2 laser mark actually bleaches the anodized coating and because the coating is not removed the aluminum frame remains electrically insulated and protected from corrosion.
Contrasting marks were produced on this anodized aluminum frame with a 25W laser.
