1.2, Branding value brought by laser engraving

Laser engraving offers tremendous branding value across various industries, especially in the jewelry sector. It allows for the precise and permanent marking of logos, brand names, and custom designs directly onto valuable materials such as gold, silver, platinum, and titanium. This not only enhances product authenticity and professionalism but also helps build customer trust. Personalized engraving—such as initials, dates, or symbols—adds emotional value, encouraging brand loyalty and repeat purchases. Moreover, the ability to engrave unique serial numbers or QR codes supports traceability and anti-counterfeiting, further reinforcing a brand’s reputation for quality and innovation.

The 20W laser marking machine, with its exceptional precision and compatibility with various metal materials, has become an ideal choice for the metal crafts and gift customization industry. It is perfectly suited for high-precision engraving on precious metals such as stainless steel, gold, silver, and titanium, and can easily achieve permanent markings like QR codes, logos, text, and patterns, ensuring each product is unique. With its compact size and low energy consumption, it’s ideal for small studios and custom workshops. Easy to operate and low in maintenance cost, it significantly enhances production efficiency and creative flexibility. For manufacturers pursuing personalized, high-quality metal gifts, the 20W laser marking machine is a powerful tool for increasing product value and brand competitiveness.

2.1, How to engrave metal gifts, key chains, lighters, medals, etc. in batches

Step-by-Step Guide to Batch Engraving Metal Gifts

1. Choose the Right Laser Marking Machine
Use a fiber laser marking machine (e.g., 20W or 30W) that is specifically designed for metal materials. Fiber lasers provide high precision and fast engraving speed, making them ideal for batch production.

2. Design Your Artwork
Use graphic design software such as Adobe Illustrator or CorelDRAW to create your logo, text, QR code, or decorative patterns. Export the design in a compatible format (usually DXF, PLT, or SVG).

3. Import the Design into the Laser Software
Use the laser machine’s control software (e.g., EZCAD) to import your design and adjust the position, size, and engraving parameters such as power, speed, and frequency.

4. Prepare a Fixture or Jig
To engrave in batches, prepare a custom fixture (jig) that holds multiple items in place at once—e.g., 10 or 20 keychains laid out in a grid. This ensures consistent alignment and speeds up the process.

5. Adjust Focus and Positioning
Manually or automatically adjust the laser’s focal length to match the height of the items. Double-check the layout using the “preview” or “frame” function in the software to avoid misalignment.

6. Start Batch Engraving
Once everything is aligned and parameters are set, begin the engraving process. The laser will automatically engrave each item in sequence without the need for manual repositioning.

7. Post-Processing (Optional)
If needed, clean the engraved items using alcohol wipes or ultrasonic cleaners to remove any debris or discoloration.

2.2, Engraving depth and clarity display comparison

When it comes to laser engraving, depth and clarity are two critical factors that determine the final quality of the mark—especially on metal surfaces like gold, silver, stainless steel, and aluminum.

Engraving Depth vs. Clarity Comparison:

• Shallow engraving offers a clean and polished look, ideal for luxury gifts, jewelry, or branding logos where precision is key.

• Deep engraving provides a tactile, rugged feel—perfect for awards, heavy-use keychains, or outdoor gear needing long-term durability.

By adjusting laser power, frequency, and speed, operators can balance both depth and clarity to meet different design needs in batch production.

2.3, How to achieve batch automatic numbering or barcode marking

1. Use Software with Variable Data Function

Most laser marking machines, especially fiber laser machines (like the 20W model), come with software such as EZCAD that supports variable data marking. This allows automatic changes between each engraving in a batch—ideal for serial numbers, barcodes, or QR codes.

• ✔ Import an Excel or CSV file with pre-set numbers/barcodes

• ✔ Or, set up auto-increment rules (e.g., 0001 → 0002 → 0003…)

• ✔ Software will update the content automatically for each item

2. Set Up a Fixture or Jig for Batch Positioning

To engrave multiple items like keychains, medals, or lighters:

• ✔ Use a custom fixture to position several items at once

• ✔ The laser head will mark each piece sequentially, guided by the software

3. Barcode or QR Code Generation

• Built-in tools can generate standard barcodes (e.g., Code128, EAN) or QR codes

• Input data can be dynamic (from serial numbers or text entries)

• The laser engraver ensures high-contrast, scannable code results on metals

4. Test for Depth and Clarity

• Adjust laser speed, power, and frequency for optimal barcode/serial marking clarity

• Ensure readability by scanners and long-term durability on metal surfaces
