By utilizing patented brightener formulations and gradient polishing techniques, we achieve optical mirror-level brightness and long-lasting color performance in electroformed jewelry coatings. During the electroforming process, specialized brighteners (e.g., sulfur-based organic compounds) are added to optimize the cathodic polarization of the electrolyte, refining the metal deposition layer to nanoscale grain size, fundamentally reducing surface roughness. The post-treatment phase employs a three-stage process—mechanical polishing, electrolytic polishing, and ultrasonic cleaning—ensuring a surface roughness of Ra≤0.05μm and achieving an optical mirror effect.

For different metal materials, we customize processing parameters: for instance, silver jewelry undergoes cyanide-free electrolytic polishing to prevent surface fogging, while stainless steel substrates undergo passivation treatment to enhance anti-fingerprint properties. We also offer differentiated surface effects such as satin, sandblasting, and laser textures to meet diverse style needs. Durability tests show that our coatings exhibit only slight discoloration (rating ≥9) after 500 hours of salt spray testing, far exceeding industry standards.

This service has been recognized by several renowned brands. For example, we provided rose gold coating treatment for a fashion jewelry brand, enabling products to exhibit softer diffuse reflection under counter lights; for a wedding series, we offered long-lasting color preservation, guaranteeing no significant fading within three years. We also provide coating maintenance guidelines to enhance end-consumer experience.
