📘 What Are Laser Engraved/Marked Tags? A Complete Guide
Introduction
Laser engraved or marked tags are durable, permanent identification labels created by using laser technology to either engrave (etch into the surface) or mark (change the surface color or structure) of a material. These tags are widely used across industrial, commercial, and personalized settings due to their precision, resistance to wear, and versatility.
What Is Laser Engraving vs Laser Marking?
Although often used interchangeably, laser engraving and laser marking have technical differences:
-
Laser Engraving: Removes material from the surface to create deep, long-lasting indentations. Best for metal tags where permanence is critical.
-
Laser Marking: Alters the surface (color change, annealing, foaming) without removing material. Ideal for anodized aluminum, plastics, and coated surfaces.
Key Benefits of Laser Engraved/Marked Tags
-
✅ Durability: Resistant to abrasion, chemicals, UV, and heat
-
✅ High Precision: Ideal for barcodes, QR codes, serial numbers, and logos
-
✅ Permanent Marking: Cannot be easily removed or tampered with
-
✅ Material Versatility: Works on metals (aluminum, stainless steel, brass), plastics, ceramics, etc.
-
✅ Customization: Supports variable data, complex designs, and small batches
Common Materials Used
Laser engraved and marked tags are compatible with a variety of materials:
| Material | Notes |
|---|---|
| Stainless Steel | High durability, corrosion-resistant |
| Anodized Aluminum | Offers contrast (black/white engraving), lightweight |
| Brass/Copper | Excellent for decorative or nameplate tags |
| Plastic/Polycarbonate | Ideal for indoor/outdoor signage, safety labels |
| Titanium | Used in aerospace or medical tagging applications |
Typical Applications
Laser engraved/marked tags are used in industries where identification must last:
-
🏭 Industrial Equipment: Machine ID plates, maintenance tags
-
🔌 Electrical Systems: Cable tags, panel labels
