Industrial Laser Marking & Metal Part Engraving

Laser marking has become the gold standard for permanent identification on metal parts across aerospace, medical device, automotive, and general manufacturing. Unlike ink stamping or adhesive labels that degrade, fade, or fall off in harsh environments, a laser-marked serial number, data matrix code, or traceability identifier is there for the life of the part. This guide brings together everything we've learned from marking thousands of metal components - from choosing the right laser process for each alloy to ensuring your marks survive heat treatment, chemical exposure, and decades of field use. (One note up front: we don't offer mechanical metal stamping or press marking - laser marking delivers the same permanent, scannable identification with no tooling, no dies, and no stress on the part.) Whether you're a manufacturing engineer setting up a traceability system or a shop owner trying to understand why your current marking process isn't holding up, the articles below cover the practical, technical, and regulatory considerations that matter.
