LASER ENGRAVING AND ETCHING
How do Laser Engraving and Etching works?
To create permanent marks, laser etching and engraving processes start with a beam of concentrated light energy.
The laser beam targets a small area of the material, known as the focal point.
The heat generated by the light energy allows the laser machine to alter the material’s surface, while the focal point ensures it affects only a specified part of the surface.
The result is a smooth, high-contrast, lasting mark, which can be human readable (serial number) or machine readable (barcode), etched or engraved into the part’s surface.
In the laser etching process, this mark will reach a depth of about 0.0001 inches. In the laser engraving process, the mark depth is typically up to 0.005 inches.
