Laser Anti-Counterfeiting Marking Equipment Sapphire Wafer Marking

Short Description:

The Laser Anti-counterfeiting Marking Machine is an industrial-grade device that utilizes laser beams to create permanent, high-precision, and difficult-to-replicate anti-counterfeiting marks on material surfaces. Through laser-material interaction, it induces micro/nanoscale structural modifications, color alterations, or chemical oxidation reactions, enabling advanced security features such as:
· Invisible encoding
· Multicolor marking
· Dynamic pattern generation
XKH systems are particularly effective for specialized materials like lab-grown sapphire, offering unique customization for jewelry, watch dials, and semiconductor substrates. Whether engraving intricate patterns on sapphire gemstones, creating bespoke designs on sapphire watch crystals, or marking traceable codes on sapphire wafers, our technology ensures flawless, durable results without compromising material integrity.

Core Principles

Laser anti-counterfeiting marking relies on the following physical/chemical effects:
1.Thermal Effects (metals/plastics): Laser heating induces oxidation, melting, or carbonization to produce contrast marks (e.g., black/gray).
2.Photochemical Effects (glass/sapphire): Short-wavelength lasers (e.g., UV 355nm) disrupt crystal lattices to form microstructural diffraction gratings, creating iridescent effects.
3.Ablation Effects (coated materials): Removal of surface layers reveals underlying colors for multi-tone contrast.

Key Technical Parameters

1.Laser Types: Fiber (1064nm), UV (355nm), Green (532nm), picosecond/femtosecond ultrashort pulses
2.Marking Precision: 10–50μm (dependent on galvanometer system)
3.Speed: 100–1000 characters/sec (varies by complexity)

Anti-Counterfeiting Mark Types

(1) Invisible/Micro Marks
Applications: High-end electronics (e.g., chips), luxury goods
Technology: UV lasers create subsurface nanostructures, visible only at specific angles or under UV light.
(2) Dynamic Color Marks
Applications: Metal watch dials, packaging
Technology: Laser-induced oxidation layers (red/blue/green) via parameter modulation (power/frequency).
(3) QR Codes/Serial Numbers
Applications: Pharmaceuticals, automotive parts
Technology: High-contrast dot-matrix engraving with database verification.
(4) Holographic Diffraction Patterns
Applications: Banknotes, ID cards
Technology: Femtosecond lasers engrave grating structures in transparent materials for dynamic optical effects.

Compatible Materials & Industries

Material	Anti-Counterfeiting Effects	Industries
Metals	Oxidation colors, deep-engraved QR codes	Luxury goods, automotive, tools
Plastics	Carbonized black/white marks	Electronics, packaging
Glass/Sapphire	Iridescent microstructures, hidden codes	Watches, phone lenses, wine bottles
Ceramics	Glaze modification	Premium fixtures, artwork
Coated Materials	Layer-selective exposure (e.g., gold-to-silver)	Credit cards, certificates

Selection Guidelines

1.Metals/Plastics: Fiber lasers (1064nm), ≥30W power, dynamic focus capability.
2.Glass/Sapphire: UV lasers (355nm) or ultrashort pulses (ps/fs) to prevent cracking.
3.High-Precision Needs: Galvo accuracy ≤±1μm with CCD vision alignment.
Critical Notes:
· Ultra-hard materials (e.g., sapphire) require parameter testing to avoid thermal cracks.
· Color marking necessitates pre-trials for stability (e.g., metal oxidation hues may age).

Laser anti-counterfeiting systems enable non-contact, high-precision, programmable marking, serving as a cornerstone of modern security technology. Their efficacy hinges on controlled laser-material interactions, mandating tailored laser sources and parameters based on material properties (hardness, thermal sensitivity).
