How latest advances in laser marking technologies are improving Direct Part Marking requirements for the Automotive Industry.
What is Direct Part Marking?
Direct Part Marking (DPM) is the process of identifying parts or final product assemblies with serial numbers, part numbers, date codes, and barcodes so that future activities such as maintenance, repair, overhaul and safety recalls can accurately identify the parts of concern and the work performed can be permanently tracked.
Parts produced for automotive assemblies are constructed from a variety of materials and can be represented in many different colors. These parts may have unique geometries and textures. Having a single solution to permanently mark all these items can be a real challenge.
New developments with laser source wavelengths, drive pattern waveforms and power options have made it easier to mark a wider range of materials to be compatible for use with laser marking systems.
