Deep Laser Engraving of Aluminum

Laser Engraving Application:

Deep laser engraving of aluminum using a paint removal process. The powder coated red aluminum part was laser marked using the i-Series Fiber Laser Kit with a 254mm lens. The part was engraved with a frequency of 50 kHz. The fastest method to remove the paint was to mark each letter in the logo individually. Removing the paint going letter by letter gave the paint less time to cool of resulting in a much faster cycle time. The red part with 0.0045" coating needed 140 seconds to be removed.

Laser Engraving Application:

This part was marked with a 20 watt q-switched ytterbium fiber laser with a 160 mm focal length lens. The sample was laser engraved to create a deep mark that would not be damaged by sand blasting. The sample was produced using a fiber laser at a setting of 17 Watts, with a frequency of 20kHz, and speed of 6 inches per second. Complete cycle time: 56.34 seconds.
