ਹੀਰਾ ਕਮਰ GIA ਨੰਬਰ ਲੇਜ਼ਰ ਉੱਕਰੀ ਮਸ਼ੀਨ ਗਰਮ ਵੇਚਣ!

Technical Depth

1. Cold Processing Principle – Photochemical Ablation Over Thermal Melting

The 355nm UV laser delivers single-photon energy as high as 3.5 eV, directly breaking the C-C bonds on the diamond surface for clean, gaseous removal. With a heat-affected zone of <1 µm, the process eliminates thermal stress and micro-cracks. GIA inspection reports confirm “zero burn marks, zero dispersion change.”

2. Micron-Level Precision – Where Detail Defines Premium

On a girdle as thin as 0.02 ਮਿਲੀਮੀਟਰ, the machine can engrave a 0.05 mm × 0.05 mm DataMatrix code. Individual characters are just a quarter the width of a human hair—crisp and sharp even under 10x magnification. Ideal for discreet branding: ਲੋਗੋ, certificate numbers, or private signatures.

3. Permanent Anti-Counterfeiting – Dual Physical + Digital Security

The laser induces random nano-textures that cannot be polished away. Each code is synchronized with a blockchain certificate, allowing instant scanning to reveal origin, cut, fluorescence, and auction history. Truly, “one object, one certificate, one code for life.”

Core Advantages

1. Zero-Damage Guarantee

Batch-tested by the National Gemstone Testing Center (NGTC), diamonds show no change in clarity, color grade, or fluorescence intensity before and after marking. Insurers directly accept the “no damage” report, maintaining original premium rates.

2. One-Time Investment, Lifetime Anti-Counterfeiting

The machine supports 24/7 continuous operation with MTBF >30,000 ਘੰਟੇ. Marks resist acid, alkali, and annealing at 800°C—lasting a lifetime without fading. Eliminates recurring costs for re-tagging, re-certification, and re-inspection.

3. Invisible Yet Aesthetic

With a focused spot size ≤10 µm and engraving depth of 50–150 nm, the mark is invisible to the naked eye and doesn’t interfere with light entry or brilliance. Only visible under 20x magnification—balancing discreet branding with professional traceability.

4. Multi-Format, Multi-Language, Multi-Material

Supports TrueType, OCR-A, DataMatrix, QR, and DM codes; ਅੰਗਰੇਜ਼ੀ, numerals, Simplified Chinese, Russian, Hindi, ਅਤੇ ਹੋਰ. Works not only on diamonds but also on ruby, sapphire, moissanite, CVD lab-grown diamonds, and other hard crystals.

5. Production-Line Efficiency

Dual vision positioning + rotary fixture enables 360° girdle marking in one go. Speeds up to 1.2 seconds per stone; integrated with automatic sorting systems, shifts yield 8,000–10,000 stones—meeting high-volume demands in Surat and Guangdong.
