The laser marker, stitched to the ERP with no manual typing

The problem

The last step before shipping still depends on someone's fingers.

the marker is the last physical step before the part leaves for shipping. One mistyped digit turns a whole lot into a hard-to-trace nonconformity, yet manual typing remains the standard method.

• The laser marker that engraves lot and part number on every shaft or piston is usually modern and has an API nobody has ever used. Nobody asked for it to be connected because it has always worked by hand.
• So on every lot change, somebody types the new values on its panel, often in a hurry because the parts washer and the packing station are waiting. On short lots, that typing happens several times per shift.
• One wrong digit turns a whole lot into a nonconformity that is hard to trace back, because the mark itself is the traceability. A wrong mark on a correct part is still a nonconformity for the OEM.
• And it happens at the last physical step, after every other control — first-off, SPC, visual inspection — has already passed. So nothing downstream is designed to catch it.

How it fits the IRIS system

Connect stitches ERP and laser marker together — two modern systems, finally talking.

Connect stitches two modern systems via API. When the ERP flags a work-order start, it automatically publishes part number, lot and heat to the marker; a lot change becomes one ERP tap, not manual marker typing.

There is nothing to buy: both systems already have interfaces. Connect makes the ERP the only place a lot is defined, and the marker simply engraves what it receives. It is the fastest payback in the matrix precisely because nothing new has to be installed. Operators stop being the weakest link at the very end of the process.

Before and after

The marker on its own versus the marker fed by the ERP

Aspect	Today	With iLEAN Connect
Lot change at the marker	Typed at its panel	One tap in the ERP
Values engraved	What was typed	Part number, lot and heat from the order
Human-origin marking errors	Occasional	Zero
Mark versus order	Never compared	Confirmed back to the ERP
Mismarking nonconformity risk	Latent on every lot	Drastically reduced
New hardware	—	None

occasional typing errors (some tied to nonconformities) → zero human-origin marking errors.

Impact estimate

Impact estimate — to be validated with your numbers.

The block below is an estimate to be validated against your plant's actual data. We put it forward so the committee has an order of magnitude; we refine it during the assessment.

• Estimated payback 3-6 months, the fastest in the matrix. Nothing new is installed, which is why the range is short.
• Drastic reduction in the risk of a mismarking nonconformity, the kind that is hardest to contain because the wrong mark looks right.
• Human-origin marking errors go from occasional to zero. Every engraved lot matches its order, and the check is recorded.
• And a lot change becomes one ERP action instead of a typing job at the end of the line. On short lots, that saves several typing jobs per shift.

fast payback, 3-6 months, drastic reduction in mismarking nonconformity risk. *Estimate to be validated*.

And the fair question from the production manager

“What if the ERP sends the wrong lot to the laser?” — the order is the single source, so any error is visible in one place instead of spread across panels. Matching the engraved fields to the order is an anchored check, where the best models drop below 1.5% error [1], and the operator confirms the first marked part of each lot before the run continues.
