Laser marking times vary...
The marking time of any part depends on how many lines the laser has to draw (every mark, whether it be text, graphics or bar codes, consists of individual vector lines drawn by the laser) and how fast the laser beam draws each of those lines. A single line drawn by a laser marker is usually on the order of .002-.004" wide. If a .1" tall bold character needs to be marked then the laser will draw many individual lines to create that bold character. The material that is being marked, the number of vector lines drawn and the depth of the marking will determine total marking time. Total cycle time is the combined marking time and part placement and removal time.
