How to Choose a Label Engraving Machine for Metal Tags?
The Critical Role of Metal Tag Engraving
Industrial asset tracking requires permanent markings that withstand harsh conditions. According to Metalworking World (2024), 87% of manufacturers now prefer engraved metal tags over stickers for outdoor use. A proper label engraving machine creates 0.2-1.0mm deep marks that last decades.
Real-World Selection Challenge
During a 2025 shipyard project, we discovered stamped tags rusted within months. Switching to a CNC engraver with 0.4mm depth solved this – tags remained readable after 3 years of saltwater exposure.
Laser vs. CNC for Metal Tags
Feature | Fiber Laser | CNC Engraver |
---|---|---|
Marking Speed | 25 tags/min | 60 tags/min |
Stainless Steel | Surface marking only | Deep engraving (0.5mm+) |
Operating Cost | $0.08/tag | $0.03/tag |
5-Step Selection Process
- Material Testing: Verify the machine handles your specific alloy (grades 304/316 SS differ)
- Depth Verification: Outdoor tags need ≥0.3mm depth – test with calipers
- Throughput Calculation: Match machine speed to your daily tag volume
- Software Check: Ensure compatibility with your label design files
- Consumable Audit: Calculate long-term tooling costs (carbide vs diamond)
⚠ Critical Warning
Avoid “all-purpose” engraving bits for hardened steel tags. Specialized 55° carbide cutters last 7x longer, saving our automotive client $18k/year in replacements.
