Frequently Asked Questions (FAQ)

1. What is fiber laser marking, and how does it work on plastic?

Fiber laser marking uses a high-intensity laser beam to alter the surface of plastic materials, either by foaming, carbonizing, or color changing the plastic. The laser’s energy is absorbed by the surface, producing a permanent, high-contrast mark without damaging the material.

2. Can all plastics be marked with a fiber laser?

Not all plastics react the same. Some plastics, especially those with light colors or certain additives, may not mark well unless treated or modified. However, with the right laser settings or the use of laser-sensitive additives, most industrial plastics can be effectively marked.

3. Is fiber laser marking safe for medical plastic components?

Yes, fiber laser marking is a non-contact and precise method, making it ideal for sensitive medical applications. It produces no residue, minimizing contamination risk. It’s widely used to comply with UDI requirements in the healthcare industry.

4. What’s the difference between engraving and marking plastic with a fiber laser?

Marking typically alters the surface without material removal, while engraving involves deeper penetration into the material. For plastics, marking is usually preferred due to the risk of damaging or warping thin materials during engraving.

5. How long does a fiber laser mark last on plastic?

Laser marks are permanent and resistant to abrasion, chemicals, and UV exposure. The durability depends on the plastic type, environment, and laser settings, but typically, fiber laser marks last the lifetime of the product.

6. Can fiber lasers mark color onto plastics?

Fiber lasers primarily create monochromatic marks, but MOPA fiber lasers can produce slight color changes on specific plastics due to controlled heat application. However, vibrant multicolor marking is usually not achievable on plastic.

7. Is fiber laser marking better than inkjet or pad printing for plastic?

Yes. Fiber laser marking is cleaner, faster, and more permanent. Unlike ink-based methods, it requires no consumables and offers better precision with minimal environmental impact.

8. How fast is fiber laser marking for plastic components?

Speed varies depending on design complexity and material. On average, a fiber laser can mark several hundred components per hour. Batch production marking can be optimized for even higher speeds.

9. What industries benefit most from laser-marked plastic parts?

Industries like automotive, medical devices, electronics, aerospace, and consumer goods rely heavily on high-quality, traceable, and permanent plastic markings for compliance and branding.

10. Can I mark curved or irregular-shaped plastic parts?

Yes, with appropriate setups and rotary attachments, fiber lasers can mark curved surfaces, cylindrical objects, and irregular shapes with precision.

11. Does fiber laser marking damage the plastic?

No, if correctly calibrated. Fiber lasers use non-invasive energy levels tailored to the plastic type, ensuring no melting, burning, or cracking occurs.

12. What support do you offer after purchase?

We provide full training, software support, maintenance guidance, and troubleshooting services to ensure your fiber laser system runs smoothly and continues delivering top-quality results.
