A label can work at receiving and disappear halfway through production.
The part moves through machining, oil, heat, cleaning, inspection, and handling.
By the time QA finds a defect, the paper label is gone.
Now the team has the part in hand, but the link to the work order, batch, rework path, or customer record is broken.
Direct part marking solves this when the identity has to stay with the part.
Laser-etched and dot-peened 2D codes can survive conditions that destroy a normal label. The scanner still has to be chosen carefully because metal surfaces, curved parts, tiny codes, low contrast, and inconsistent lighting make DPM reads harder than standard label scans.
Test the ugly version of the job.
Oily part.
Curved surface.
Small code.
Low contrast.
After wash.
After heat.
After handling.
Lowry’s GM direct part marking case used handheld computers with 2D imagers to read laser-etched and dot-peened marks during defective part handling.
The goal is simple:
when the part reaches inspection, rework, or warranty review, the mark still proves what it is.
