30W–200W Powder Coated Laser Marking Machine for Metal & Aluminum

Permanent Laser Marking for Epoxy Polyester Powder-Coated Steel

Epoxy polyester powder-coated steel tubes are widely used in furniture, shelving systems, curtain rods, fitness equipment and other metal products where long-lasting identification is essential. Unlike labels or ink printing that can peel, fade or wear away over time, fiber laser marking creates permanent, high-contrast graphics directly on the powder-coated surface.

HND LASER has optimized its fiber laser process specifically for epoxy polyester powder coatings, producing clean, consistent markings on both black and white coated steel tubes. The laser precisely removes only the upper coating layer to create a visible contrast while preserving the coating's adhesion and corrosion resistance.

Whether the surface features a matte or semi-gloss finish, the marking remains sharp, durable and easy to read throughout the product's entire service life.Typical applications include installation instructions, IKEA-style assembly graphics, logos, QR codes, serial numbers, traceability information and safety symbols.

Why Fiber Laser Marking for Powder-Coated Steel?

Traditional identification methods often struggle to maintain durability on powder-coated products. Adhesive labels can detach during transportation, while ink printing gradually fades after repeated handling or long-term use.

Fiber laser marking offers a permanent solution by interacting directly with the epoxy polyester powder coating. Without using ink, solvents or consumables, it produces crisp graphics with excellent contrast while maintaining the appearance and protective properties of the coating.

1.Permanent Identification
The marking becomes part of the coated surface and remains readable throughout the product lifecycle.
 
2.Excellent Contrast
Optimized laser parameters deliver clear, high-visibility markings on both black and white powder-coated steel.
 
3.Preserve Surface Integrity
Only the coating surface is selectively processed, helping maintain the original coating adhesion and corrosion resistance.
 
4.Maintenance-Free Production
No labels, ink cartridges or chemicals are required, reducing operating costs and minimizing maintenance.
 
5.Suitable for Automated Manufacturing
The system can be integrated into rotary fixtures, conveyor lines and fully automated production systems for high-volume manufacturing.
