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 is a process that roughens the metal surface by spraying abrasives such as sand or emery at high pressure, creating a fine and uniform matte texture. This treatment gives the card a subtle yet smooth satin feel, enhancing its luxurious in-hand experience. The matte surface absorbs rather than reflects light, presenting a more refined and sophisticated appearance while effectively concealing fine scratches.
Spin Hairline is a unique surface machining technology that creates distinctive concentric circular patterns on the metal surface. By applying a rotating abrasive tool with precise control of pressure, speed, and contact time, a uniform and rhythmic circular texture is formed. This process not only delivers a unique visual effect but also adds dynamic beauty and artistic flair through the interplay of light and shadow.
Polishing is a finishing technique that finely grinds the surface to achieve a smooth, mirror-like gloss. By removing fine scratches, imperfections, and roughness, it imparts a high-luster, reflective finish that significantly enhances the aesthetic value and premium feel of the product. Increased surface smoothness also reduces friction and improves corrosion resistance to a certain extent.
Hair Line treatment involves polishing the metal surface with sandpaper or an abrasive belt in a consistent unidirectional motion, resulting in fine, uniform, hair-like linear textures. This process preserves the natural metallic feel while adding a subtle sheen and tactile depth, further elevating the card’s luxurious appearance. The fine texture also effectively masks fingerprints and minor scratches, making the card easier to maintain in daily use.
Each surface treatment represents a deep integration of function and aesthetics. Xinyetag 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.
