Serial Number and Traceability with Laser Marking: A Complete Control Guide for Production
Serial number laser marking is a core application that enables products to be uniquely identified and tracked throughout production processes. In industrial manufacturing, a unique identity can be assigned to each part, allowing the product’s production date, lot number, and production line information to be tracked. With fiber laser, CO₂ laser, and UV laser systems, serial numbers, DataMatrix, and QR codes can be marked on metal, plastic, and other materials. This guide explains serial number marking processes, traceability systems, and production integration in detail.
Serial Number and Traceability Systems
What is a serial number?
A serial number is a unique code that enables each product to be individually identified.
What is traceability?
Traceability enables a product to be tracked from production to the end user.
Advantage of laser marking
Laser marking provides permanent and non-erasable marking.
Use of DataMatrix
2D codes improve traceability with high data capacity.
Use of QR code
QR codes provide fast reading and data access.
Lot and batch coding
Production batches can be coded with laser.
Automation integration
Laser systems can work integrated with ERP and MES systems.
Camera verification
The readability of the codes is checked with camera systems.
Quality control processes
Quality control should be performed after marking.
Industrial application areas
- Automotive manufacturing
- Electronics industry
- Medical device manufacturing
- Food and packaging
