Direct Part Marking (DPM)

Direct Part Marking (DPM) is a process to permanently mark parts to allow the tracking of parts through their full life cycle.

DPM is used by aerospace, automotive, electronics and other manufacturers to facilitate reliable identification of parts to assist in data logging for safety, warranty issues and satisfy regulatory requirements.

They are many ways to mark parts with a machine-readable code but the fastest for volume production and most reliable for industrial environments is a Microdot marker. Microdot marking delivers high quality marking at high speeds over a wide variety of materials; control of speed, dwell and impact. Thus deformations, tensions and breaks in the work piece can be avoided.

For rating plates or to give a high quality finish the most popular method is by engraving machine, either using a rotating cutter to produce a deep indelible mark or diamond to score into coloured anodised aluminium.

The preferred codes are Data Matrix and QR Code. Data Matrix is preferred by equipment manufacturers and QR Code is commonly used in automotive industries.
