Green Laser Marking Machine

Green Laser Marking Machine – Precision with Cold Light Technology

The Green Laser Marking Machine operates at a 532 nm wavelength, positioned within the visible light (green) spectrum. This shorter wavelength provides two major advantages over the 1064 nm fiber laser:

1. Superior absorption in certain materials—especially highly reflective metals such as gold and silver.
2. Reduced thermal impact, often described as “cold light precise marking.”

Key Features and Precision

1. Reduced Thermal Stress (Cold Marking)
Similar to UV laser technology, the green laser minimizes heat input, preventing deformation, burning, or micro-cracking. This makes it ideal for sensitive materials, micro-electronics, and precision components.

2. Excellent Absorption on Reflective Metals
The 532 nm wavelength is highly absorbed by reflective materials like gold, silver, and copper, which are difficult to mark using conventional fiber lasers. The result is sharp, high-contrast, and permanent marks with exceptional clarity.

3. Specialized Glass and Crystal Processing
Highly effective for engraving, drilling, and surface marking on glass, crystal, ceramics, and transparent materials, where extreme precision and minimal material stress are required.

4. High-Quality Detail
Produces ultra-fine, high-resolution markings, suitable for microscopic text, intricate logos, and complex pattern engraving—particularly on electronic components and fine plastics.

Common Applications

• Precision marking and drilling on glass, crystal, and ceramics.
• High-quality engraving and serializing on jewelry and luxury metals (gold, silver).
• Marking sensitive electronic components such as PCBs and IC chips.
• Engraving on keyboards, thin films, and plastic housings.
