Fiber Laser Marking System for Metal

Introduction

A Fiber Laser Marking System is a high-precision tool that uses a fiber laser beam to permanently mark or engrave metals and other hard materials. It operates by focusing a laser beam onto a metal surface, which results in high-contrast, durable markings like barcodes, serial numbers, logos, or QR codes. Unlike traditional engraving, fiber laser marking is non-contact, highly efficient, and maintenance-friendly. It’s widely adopted in industries like aerospace, automotive, medical devices, jewelry, and electronics due to its speed, accuracy, and consistency.

Frequently Asked Questions (FAQs)

1. What is the difference between fiber laser marking and engraving?

Answer:
Fiber laser marking changes the surface color of the metal by oxidizing it through laser heat, without physically removing any material. It's ideal for fast, shallow, high-contrast marks.
Engraving, on the other hand, involves removing material to create a deeper impression. While both use a laser, engraving generally takes more time and produces more wear on the surface.

2. Can a fiber laser mark coated or painted metals?

Answer:
Yes, fiber lasers can mark coated or painted surfaces, although results may vary depending on the coating thickness and composition. In some cases, the laser will remove the coating to expose the base metal; in others, it might discolor the surface without penetration. It’s always recommended to test sample parts before full production.

3. Is it safe to use a fiber laser marking machine in a regular workspace?

Answer:
Fiber laser systems are relatively safe, especially when enclosed and fitted with safety interlocks. However, proper safety protocols must be followed, such as using protective goggles, operating in a designated laser-safe area, and adhering to laser safety class guidelines. Most industrial units are Class 1 when enclosed and Class 4 when open.

4. How do I maintain a fiber laser machine?

Answer:
Fiber laser machines require minimal maintenance. Key practices include:

Keeping the lens and galvo head clean.
Ensuring the air-cooling system is functional.
Regular software updates.
Avoiding high humidity or dust-laden environments.
These machines have no consumables, which significantly reduces maintenance tasks.

5. How long does it take to mark a product?

Answer:
The marking time depends on the complexity of the design, size of the area, and type of material. For example, a simple serial number can be marked in less than a second, while complex logos or barcodes may take 2–5 seconds. The system is ideal for high-throughput production.

6. Can fiber lasers mark plastics or non-metals?

Answer:
Fiber lasers are primarily optimized for metals. However, they can mark some engineered plastics and polymers (like ABS or polycarbonate) with proper settings. For marking organic materials (wood, glass, leather), CO₂ or UV lasers are better suited.
