Laser Marking Aluminum Settings

Laser Marking Aluminum Settings. 100%k the ˜rst setting to adjust is PPI On some lasers PPI (pulses per inch) can be adjusted 1000 is the ideal setting if it can be changed Step 2 — DPI Next variable is DPI (dots per inch) this needs to be at least 600 1000 will give a slightly wider range of ideal settings but will take more time to lase pieces.

Get the right mark by focusing on laser power repetition rate marking speed and fill spacing What are you looking for? The ideal is a white‐metallic mark which is consistent across the mark area (the picture on the far left) Before marking prepare parts for success ­– Make sure the part is lying flat with respect to the laser and within the marking field For best results be sure to clean the part of all debris and oils – use ethanol or acetone to wipe the surface clean Use the right settings – I’ve listed what I think is a good starting point for laser parameter settings These settings are what I would recommend for a 20W fiber laser marker with 6x beam expander and 160mm f‐theta lens Consider a second pass – A second high speed high frequency pass brightens the white Use the same settings as above except use a 150‐200 kHz repetition rate and scan the part perpendicular to the first pass.

Laser Marking Anodized Aluminum AMADA WELD TECH

In order to make a high quality permanent mark using CerMark laser marking materials it is critical to use the correct laser settings which make the materials successfully bond to the substrate While the “process window” is quite wide for a number of materials being marked much will depend on the type of laser being used and the settings that have been applied.

Adjusting Your Laser Guide To Laser Marking Setting

laser engraving on aluminum delivers marks that can withstand mechanical stress repeated abrasion UV exposure and temperature stress This is a very important feature if you are creating marks to be used for quality control and traceability as in the case of aircraft and automotive parts.
