    Ultimate invisibility, evolutionary design

    Deeply embedded solution: The hinge body is accurately embedded into a 25mm thick door panel (solid wood/composite board), with only a 0.5mm extremely narrow nickel metal outline exposed on the surface, achieving a "zero presence" connection between the door panel and the cabinet, and is suitable for minimalist designs such as frameless glass doors and suspended cabinets.  
    Industrial aesthetic gene: The matte nickel-colored electroplated surface is fingerprint-resistant and scratch-resistant, and is seamlessly integrated with stainless steel, concrete, dark wood veneer and other materials, giving the space a cool and high-end texture expression.
    Heavy load innovation, mechanical breakthrough
    Dual engine load-bearing system:
      Cross-folding structure: 16×70mm enlarged hinge base, combined with X-shaped mechanical layout, to disperse door panel pressure. The double hinges can carry up to 30kg of overweight doors (such as full-face slate doors, solid wood bookshelves).  
      Military-grade reinforced pin: 14mm diameter stainless steel pin + self-locking bearing, impact resistance increased by 70%, eliminating hinge loosening or door panel tilt caused by high-frequency use.

    Dual-material defense, long-lasting promise

    Zinc alloy body: high-pressure integrated die-casting, lightweight design reduces the burden on the door panel, and the anti-deformation index reaches 2 times the industry standard.  
    Stainless steel core: The bearings and connectors are made of 316 medical-grade stainless steel, which has passed 10,000 opening and closing tests and a 96-hour salt spray corrosion test. There is no risk of rust in humid and high-salt environments (beach villas, SPA rooms).  
    Intelligent adaptation, comprehensive coverage
    Free thickness: except for standard 25mm door panel requirements.  
    Scene expansion: Provides three opening and closing angles of 90°~180°, suitable for swing doors, folding doors, and multi-stage hidden sliding door systems, unlocking diverse scenarios such as commercial exhibition halls and luxury cloakrooms.

    Technical parameters

    Material: zinc alloy (base) stainless steel (bearing & pin)
    Surface technology: matte nickel color nano-coating (weather resistance IP54)
    Single hinge load-bearing: 15kg | Double-hinge group load-bearing: 30kg)
    With invisible power, it carries explicit needs - this hinge is not only a hardware accessory, but also a strategic partner for space designers to achieve "de-tooling" aesthetics.
