Ultrafast Laser Rainbow Marking Machine Metal Interference Stripes With Dynamic Angle-Shift Rainbow Effects

Product Overview

The Ultrafast Laser Rainbow Marking Machine is a high-end system utilizing ultrafast laser technology. It generates dynamic rainbow effects on mirror-like surfaces (e.g., stainless steel, PVD coatings) through nano-scale physical interference patterns created by high-peak-power lasers. The machine supports direct processing on metals and transfer printing to plastics/films, combining anti-counterfeiting and decorative functions. It is widely used in luxury goods, cosmetic packaging, commemorative coins, and security labels.

Technical Principles

• Ultrafast Laser Processing: High-peak-power lasers create nano-scale physical stripes on material surfaces through ionization, producing rainbow dispersion via light interference and diffraction.​​

• Customized Optical Design: Dynamic control of laser paths ensures multi-angle visibility of rainbow effects.

​

• Software Control: Built-in software adjusts optical paths for complex patterns and enables effect transfer to other materials.

Specification

Applications

1. Security Labels: Anti-counterfeiting tags for pharmaceuticals, cosmetics, tobacco/alcohol packaging, and holographic reliefs on currency/coins.

2. Luxury Packaging: Rainbow laser decoration on stainless steel/PVD cosmetic cases and jewelry tags.

3. Industrial Materials: Nano-structure processing on solar panels to reduce reflection and improve efficiency.

4. Transfer Printing: Rainbow effects transferred to plastics, precious metals, and films via molds.

Q&A

Q1: How does the rainbow effect prevent counterfeiting?
A1: Nano-scale physical stripes created by ultrafast lasers cannot be replicated by conventional methods. The color-shifting effect varies with viewing angles, making duplication extremely difficult.

Q2: What materials are compatible?
A2: Direct processing materials: stainless steel, mold steel, nickel, chrome, PVD coatings. Transfer materials: plastics, jewelry, precious metals, films.

Q3: Can anti-counterfeiting solutions be customized?
A3: Yes, including angle-dependent patterns or micro-features embedded in designs for industry-specific needs.
