1.2, Process customized gifts (gold medals, commemorative coins)

• 1. Why Use a Laser Marking Machine for Gold Gifts?

Permanent & High-Quality Markings: Laser engraving creates scratch-proof, fade-resistant designs.

Fine Details: Perfect for intricate logos, text, serial numbers, or portraits.

No Contact Process: No physical pressure, ensuring no damage to delicate gold surfaces.

Customizable: Works with 24K gold, gold-plated items, and gold alloy medals/coins.

• 2. Types of Gold Items Suitable for Laser Marking

Gold Medals (Sports, Awards, Trophies)

Commemorative Coins (Corporate, Military, Event Souvenirs)

Jewelry (Gold Rings, Pendants)

Plaques & Nameplates

• 3. Laser Marking Process for Gold Gifts

Step 1: Design Preparation
Use vector-based software (CorelDraw, AutoCAD, Adobe Illustrator) to create the desired text, logo, or artwork.

Common engravings:

Names, dates, event details

Serial numbers (for limited editions)

QR codes (for authenticity verification)

Intricate patterns or portraits

Step 2: Machine Setup
Fiber Laser (Best for Metals): 20W–50W fiber lasers are ideal for gold marking.

Parameters Adjustment:

Power: Medium to high (depends on gold thickness)

Speed: Slower for deeper marks

Frequency: Higher for finer details

Step 3: Laser Marking
The laser beam removes the top layer of gold, creating a contrasting mark (dark or bright, depending on settings).

For gold-plated items, the laser can expose the base metal (e.g., brass, stainless steel) for a two-tone effect.

Black Marking Option: Using special settings, the laser can create a black oxidized finish for high contrast.

Step 4: Post-Processing (Optional)
Polishing: For a smoother finish.

Cleaning: Remove any residue with alcohol or ultrasonic cleaning.

Protective Coating: Apply lacquer to prevent tarnishing.

• 4. Advantages Over Traditional Engraving

✔ Higher Precision – Can engrave micro-text and complex graphics.
✔ Faster Production – Takes seconds per piece, ideal for bulk orders.
✔ No Tool Wear – Unlike mechanical engraving, lasers don’t degrade.
✔ Eco-Friendly – No chemicals or inks required.

• 5. Applications in Customized Gifts

Corporate Awards: Employee recognition, anniversary coins.

Sports Trophies: Gold medals with winner names & dates.

Memorial Coins: Military, graduation, or event souvenirs.

Luxury Branding: High-end jewelry & limited-edition collectibles.

6. Choosing the Right Laser Machine

B. QR Codes / Data Matrix Codes

• Stores encrypted product info (manufacturer, date, batch).

• Scannable via smartphone for instant authentication.

C. Micro-Text & Hidden Engravings

• Tiny text (0.1mm or smaller) invisible to the naked eye.

• Requires magnification to verify.

D. Holographic Laser Marks (Nanostructuring)

• Creates light-diffracting patterns that change appearance at different angles.

• Extremely difficult to replicate.

E. Invisible UV Marks

• Only visible under UV light (used for covert security).

2. How Laser Marking Prevents Counterfeiting

• Gold Medals & Awards – Ensure only genuine products are awarded.

• High-End Jewelry – Combat counterfeit luxury items.

• Limited Edition Collectibles – Track ownership and provenance.

5. Best Laser Machines for Anti-Counterfeiting

6. Advantages Over Traditional Methods

Hard to Replicate – Lasers create ultra-fine details.
No Wear & Tear – Unlike ink stamps or embossing.
Automation-Friendly – Batch marking with unique IDs.
Eco-Friendly – No inks or chemicals.

Imagine holding a 24K pure gold medal in your hands—perhaps an Olympic champion’s pride or a company’s lifetime achievement award. How do you make such an honor last forever?

In the past, artisans painstakingly carved with chisels, but the metal could warp, and the engravings would fade. Later came mechanical engraving, yet intricate designs often left the machines struggling. And let’s not forget those ink-printed serial numbers that would eventually wear off…

Then came laser marking—like magic for medals:

• A beam of light flashes, etching a microscopic 0.01mm anti-counterfeit code, nearly impossible to replicate even under a magnifying glass

• The gold surface remains untouched, yet permanently bears the winner’s name and a unique QR code

• Laser heads hum along production lines, personalizing thousands of medals per day, each with distinct designs

• No toxic chemicals, no metal debris—just flawlessly crisp, enduring markings

This is why high-end custom gifts now rely on laser engraving. It doesn’t just preserve each piece’s uniqueness—it turns prestige into permanence. When winners trace their fingers over the laser-engraved ridges, they’re touching a perfect fusion of tradition and cutting-edge technology.

2.1, No contact, no damage to the surface

Unlike traditional engraving that risks scratches and pressure marks, laser technology delivers flawless personalization through pure light. A single beam dances across your gold surface—no physical contact, no compromise to its pristine finish. The result? Crystal-clear markings that preserve every micron of your medal’s original brilliance while adding permanent distinction.

This is the art of invisible craftsmanship: all the prestige of deep engraving, none of the wear. Your treasures remain untouched, yet transformed forever.

“Where light writes, value remains pristine.”

2.2, Permanent marking, no fading, no shedding

Beneath the surface of every laser-marked gold piece lies an extraordinary metallurgical transformation. Through precisely controlled photothermal energy, our nanosecond-pulsed lasers induce a permanent structural reorganization at the atomic level:

1. Selective Surface Modification
   The laser’s 1064nm wavelength targets gold’s electron clouds, generating 8,000°C micron-scale plasma that:
   • Vaporizes surface oxides
   • Creates permanent grain boundary realignment
   • Forms sub-surface alloyed layers when marking gold-plated items

2. Self-Protective Oxidation
   The process generates an ultra-thin (50-100nm) oxidation layer that:
   • Bonds chemically with the base material
   • Develops natural corrosion resistance
   • Maintains contrast stability through nanocrystalline restructuring

3. Depth-Controlled Fusion
   Our MOPA lasers achieve 5-200μm penetration by:
   • Adjusting pulse duration (20-200ns)
   • Modulating frequency (20-100kHz)
   • Controlling thermal diffusion to prevent collateral annealing

Why This Matters for Heirloom Quality:
• No adhesives = No delamination risk
• Sub-surface modification = No abrasive wear
• Oxide integration = Natural UV resistance
