Precise, cost efficient marks and codes
Laser marking and coding are closely related applications. Marking involves creating a contrasting surface mark on the target material through ablation, discoloration, engraving, texturing, or surface melting. Coding is a type of marking, where rather than marking a static graphic or text, the mark varies, either from item to item as in a serial number, or from batch to batch as in an expiration date. Barcodes, QR codes, expiration dates, graphics, and alphanumeric codes can all be accomplished with a laser system on a wide range of material types.
Marking and coding with a laser system offers several key advantages over traditional methods:
Common Materials
Request an Application or Material Test
Character readability is crucial, enabling consumers, manufacturers, and the distribution network to properly record and if necessary, trace products back to their origins
Graphical marking a laser creates images ranging from simple shapes to logos to full grey-scale images on a wide range of materials and products
Machine-readable codes enable accurate tracing throughout the product lifecycle from the original manufacturer through distribution, use, and during any recalls
Ultrafast lasers provide cold marking or processing, so the material is removed or altered with little to no heat affect
