Permanent Laser Marking for Powder Coated Metal

Application Background

Powder-coated metal products are widely used in furniture and home decoration industries due to their excellent corrosion resistance, durability, and attractive surface finish.

For curtain rod manufacturers, permanent identification such as logos, product codes, and traceability information is required after powder coating.

This application demonstrates how Powder Coated Metal Laser Marking technology provides a permanent marking solution for coated metal curtain rods without damaging the surface finish.

Customer Challenge

After powder coating, traditional marking methods face several limitations:

1. Ink printing can fade during transportation or long-term use.

2. Labels may peel off from coated surfaces.

3. Mechanical engraving may damage the protective coating.

The customer required a marking solution with:

• Permanent identification
  High contrast marking result
  No coating damage
  Stable quality for mass production

HND Laser Solution

To solve these challenges, HND provided a customized Powder Coated Metal Laser Marking solution based on pulse fiber laser technology.

The laser precisely removes or modifies the coating layer to create permanent marks directly on the curtain rod surface.

The solution enables:

• Logo marking

• Serial number marking

• Product traceability marking

• Customized identification

Laser Marking Process

The curtain rod is positioned on the working platform, and the laser parameters are adjusted according to:

• Powder coating thickness

• Coating color

• Required marking contrast

• Product surface condition

The non-contact laser process creates clear marks while maintaining the original coating quality.

Marking Results

Permanent Marking Without Affecting Surface Quality

The final marking result shows:

• Clear logo and text

• Sharp marking edges

• Stable contrast

• Permanent identification

Compared with traditional printing methods, laser marking provides better durability and a cleaner appearance for high-value furniture components.
