Contrasting marks were created on a lacquered aluminum cap
|
Sealed CO2 lasers are useful in a wide range of applications in the packaging industry. The lacquered aluminum cap in the photo on the left was marked using a Synrad 25W sealed CO2 laser and FH Series Marking Head. The cap provided clean contrasting marks using 22W of power at 35 inches per second. Focusing was through a 125 mm lens that provided a 180-micron spot, with a 3 mm depth of focus. The seven-character mark, 0.085 inches high, was marked in a cycle time of 0.14 seconds.
