A metal card is more than just a tool for identification or payment—it is a tactile medium that conveys brand identity and customer connection. A card with distinctive weight, sound, and texture can instantly communicate values such as prestige, reliability, and exclusivity. Leveraging years of in-depth R&D and craftsmanship in the high-end smart card industry, Guangdong Xinye Intelligence Label Co., Ltd. offers a diverse range of surface treatment techniques for metal cards, ensuring each card becomes a unique “brand artifact.”
The surface finish of a metal card directly influences its tactile feel, visual appeal, and durability. We provide multiple refined surface treatment options to meet the aesthetic preferences of different brands and users.
Sanding: Gently roughens the metal surface using high-pressure abrasives such as sand or emery, creating a refined matte texture that softly absorbs light rather than reflecting it. The result is a subtle, sophisticated appearance with a warm, non-slip tactile feel that conceals fingerprints and minor scratches, keeping the card looking pristine through daily use.
Spin Hairline: Uses precisely controlled rotating abrasive tools to form elegant circular radial patterns on the metal. By fine-tuning pressure, speed, and contact time, we create dynamic, flowing concentric rings that shift beautifully under light. The tactile concentric texture adds depth and movement, turning every card into a miniature piece of kinetic art that instantly elevates perceived value.
Polishing: Brings the surface to a flawless mirror finish by progressively eliminating fine scratches, imperfections, and roughness. The result is a dazzling, glass-like luster that catches and reflects light with breathtaking clarity. The ultra-smooth surface feels silkily cool to the touch, while significantly enhancing corrosion resistance—ideal for premium financial cards and luxury VIP credentials.
Hair Line: Involves unidirectional polishing with abrasive belts or sandpaper, producing delicate, hair-like linear strokes across the metal. This treatment preserves the raw character of the material while adding a subtle sheen and refined texture. Hairline effectively masks fingerprints and light scratches, making maintenance effortless and delivering an understated elegance that never goes out of style—perfect for executive business cards and high-end access credentials.
Each surface treatment represents a deep integration of function and aesthetics. Xinyerfid not only provides these exquisite finishing techniques but also seamlessly integrates them with smart and secure modules such as RFID/NFC chips, magnetic stripes and personalized printing. We offer a one-stop customized solution for high-end metal cards—from design and craftsmanship to mass production—allowing your brand to be truly felt and remembered through the weight, sound, and touch of a single card.
