1. Vehicle Identification Number (VIN) Marking
What it is: The 17-character VIN is the legal identifier for every vehicle, required by law in virtually every market worldwide.
How lasers are used:
- Fiber lasers engrave the VIN directly into the vehicle body (typically the dashboard bulkhead or B-pillar)
- Character height: typically 7–10mm
- Depth: 0.1–0.3mm for durability and tamper resistance
- Marking time: 20–40 seconds per VIN
Why laser over alternatives:
- Dot-peen is slower and produces rougher characters
- Inkjet labels can be removed or forged
- Laser marks are permanent, deep, and tamper-evident
- Automatic readability with vision systems
