UV Laser Marking on Metal Materials

UV laser marking machines are highly effective for creating precise, permanent marks on metal surfaces. Here's what you should know about this process:

How UV Laser Marking Works on Metals

• Uses short-wavelength ultraviolet light (typically 355nm)

• Operates through a cold marking process that doesn't rely on heat

• Creates high-contrast marks by altering the metal's surface properties

Advantages for Metal Marking

1. High Precision: Can create marks as small as 0.01mm

2. No Thermal Damage: Minimizes heat-affected zones

3. Permanent Marks: Resistant to fading, corrosion, and wear

4. No Consumables: Doesn't require inks or chemicals

5. Versatility: Works on various metals including:

• Stainless steel

• Aluminum

• Titanium

• Copper

• Gold and silver (for jewelry)

Common Applications

• Medical device marking (surgical tools, implants)

• Electronics component identification

• Aerospace part traceability

• Jewelry engraving

• Precision tool marking

• Automotive part identification

Considerations for Optimal Results

• Surface preparation may be needed for some metals

• Marking parameters (power, speed, frequency) must be adjusted for different metals

• Some metals may require special coatings or treatments for best contrast
