Fiber Laser Marking Equipment

Fiber Laser Marking Equipment Introduction

Fiber laser marking machines are high-precision devices used to engrave or etch permanent marks on a wide range of materials using a focused beam of light generated by a fiber laser source. These machines are widely used in industries such as electronics, automotive, medical devices, aerospace, and jewelry due to their speed, accuracy, and ability to mark on metals and some plastics.

How It Works

A fiber laser emits a concentrated beam of light through optical fibers doped with rare-earth elements like ytterbium. The laser beam interacts with the material's surface, causing oxidation or evaporation, which results in high-contrast, long-lasting marks.

Key Features of Fiber Laser Marking Equipment

1. What materials can a fiber laser mark?

• Metals: Stainless steel, aluminum, brass, copper, titanium, gold, silver.

• Plastics: ABS, PVC, polycarbonate (with proper laser settings).

• Others: Some ceramics and coated materials.

2. What is the lifespan of a fiber laser source?

• Most fiber lasers have a lifespan of 50,000–100,000 hours, significantly more than CO₂ or diode lasers.

3. Is fiber laser marking permanent?

• Yes, it creates highly durable, tamper-proof marks that resist wear, corrosion, and high temperatures.

4. What industries use fiber laser marking?

• Automotive, aerospace, electronics, medical, jewelry, defense, and manufacturing.

5. Do I need special training to operate the machine?

• Basic training is usually sufficient. Most machines come with user-friendly software and manuals.

6. How is it different from CO₂ or UV lasers?

• Both! You can adjust the power and speed settings for deep engraving or surface etching.

8. What maintenance is required?

• Minimal. Clean the lens periodically and keep the working area dust-free.
