Ultrafast Laser Rainbow Marking Machine Metal Interference Stripes

Short Description:

Overview:

The Ultrafast Laser Rainbow Marking System is an advanced nano-marking solution that utilizes femtosecond-class laser pulses to etch precise nanoscale surface patterns on reflective materials. These nanostructures interact with light to produce vivid, angle-dependent rainbow effects—entirely pigment-free and highly durable. Beyond decorative value, these features provide a formidable anti-counterfeiting measure. The system allows for direct structuring on metals and indirect transfer to plastics and films via molding, making it ideal for high-end product branding, authentication, and artistic applications across multiple industries.

FAQs

Q1: How does the rainbow marking contribute to anti-counterfeiting?
A1: The iridescent effect stems from nano-level interference patterns created through ultrafast laser structuring. These complex, angle-sensitive visuals are nearly impossible to replicate using standard manufacturing or printing methods, ensuring strong protection against forgery.

Q2: What materials are compatible with this system?
A2: The machine can directly process metals such as stainless steel, chromium, nickel, and various PVD-coated surfaces. For other materials such as plastic, film, and soft metals, a mold-based transfer process is used to replicate the rainbow pattern.

Q3: Can the rainbow effect be customized for specific applications?
A3: Yes, designs can be tailored to include angle-specific visuals, micro-features, logos, and concealed symbols that only appear under certain lighting or viewing angles—meeting the needs of brand protection, currency verification, and artistic styling.

Q4: Is this system suitable for industrial-scale production?
A4: Absolutely. With marking speeds up to 3000 mm/s and robust thermal management, the system is designed for high-throughput environments and 24/7 operation on production lines.
