Fiber Laser Marking Technology

Fiber Laser Marking Technology

Introduction

Fiber Laser Marking Technology is a state-of-the-art solution for creating high-precision, permanent marks on a wide range of materials—especially metals and industrial plastics. Using a fiber optic laser source, this method delivers concentrated light energy to the surface, enabling fast, contactless, and highly detailed markings without physical wear or consumables.

This technology is widely adopted across industries including automotive, aerospace, electronics, medical devices, and jewelry due to its unmatched reliability, versatility, and cost-efficiency. From serial numbers and barcodes to logos and decorative text, fiber laser marking ensures clarity, permanence, and quality in every impression.

Extended FAQ – Fiber Laser Marking

Q1: What is fiber laser marking?

A: Fiber laser marking is a method of applying permanent marks to a surface using a concentrated laser beam generated through fiber optics. The beam interacts with the material surface, creating a visible and often tactile mark.

Q2: Is the marking permanent?

A: Yes. Fiber laser marks are extremely durable, resistant to wear, chemicals, and high temperatures, making them ideal for industrial and regulatory applications.

Q3: What’s the difference between laser marking, engraving, and etching?

• Marking: Surface alteration (oxidation, annealing) with no material removal

• Engraving: Material is vaporized or removed to create depth

• Etching: Similar to engraving but shallower; often used interchangeably

Fiber lasers can do all three, depending on settings.

Q4: What materials can be marked?

A: Metals and many plastics are ideal. Common materials include stainless steel, aluminum, copper, ABS, and polycarbonate. Some coated ceramics and leathers are also compatible.

Q5: How deep can fiber laser engraving go?

A: Depending on power and material, engraving depths can range from 0.01 mm (fine detail) up to 1 mm or more with high-powered systems (e.g., 50W+).

Q6: Does it require consumables?

A: No. Unlike inkjet or chemical methods, fiber laser marking requires no inks, chemicals, or stencils—reducing operational costs significantly.

Q7: Is it environmentally friendly?

A: Yes. It’s a clean, dry process with no emissions, no waste, and no hazardous substances.

Q8: What file types does the software support?

A: Most fiber laser software (e.g., EZCAD) supports formats like AI, DXF, PLT, BMP, JPG, PNG, and variable data imports (e.g., CSV, Excel).

Q9: Can I automate the marking process?

A: Yes. Fiber laser systems integrate easily with conveyors, robotics, and PLC systems, enabling inline automation for industrial production.

Q10: Can I mark on curved surfaces?

A: Yes. With a rotary axis or adjustable focal system, the laser can engrave round or curved objects such as pipes, rings, and tumblers.

Q11: Is it safe?

A: Yes. When used with proper safety gear and enclosures (Class I or IV), fiber laser marking is a safe and controlled process.

Q12: How long does a fiber laser last?

A: The average fiber laser source lasts up to 100,000 hours, making it a reliable long-term solution for high-volume operations.
