Save big on after-sales, ‘cause replacing the whole hinge? That’s so last season. - **Force Stages? Switch at Your Whim**: A simple twist on the pre-pressing screw, and you’re bouncing between two force modes. It’s tailor-made for any door, any vibe—total control, no sweat. - **4-in-1 Marvel: Hinge, Closer, Stopper, Positioner**: Why clutter with multiple hardware? This hinge is a one-stop shop—buffers, positions, closes doors flawlessly. It’s the Swiss Army knife of door hardware, minus the knife. - **175° Wide Open & Smart Motion Mastery**: Your door swings open to a jaw-dropping 175° and locks into place. Hover freely from 85°-130°, auto-close below 85°, and dampen tight below 20°—it’s like your door has a mind of its own, and it’s brilliant. - **Long-Life Loop: Refresh, Don’t Replace**: When damping gets lazy, swap the damper and boom—good as new. This hinge isn’t just a buy; it’s a long-term, low-fuss investment.

With an innovative split design, it reduces component wear and boosts durability vs traditional integrated hydraulic hinges. The core series delivers 500,000 opening-closing cycles, far exceeding industry norms. Adopts an oil-free power chamber configuration that eradicates the hazard of oil seepage—a long-standing drawback plaguing conventional hinges. Additionally, its springs and dampers are detachable and replaceable, substantially cutting down post-sales maintenance expenses for users. Boasts a 4-in-1 integrated design (hinge, door closer, door stop, and positioner), obviating the requirement for extra independent components and streamlining both installation and usage processes. Offers flexible angle customization: it accommodates a maximum opening angle of 175°, enables free positioning between 85° and 130°, and allows for effortless switching between two-stage force settings. Moreover, it maintains reliable performance within a temperature range of -37℃ to 60℃, making it adaptable to diverse climatic conditions. Features user-centric installation: most models offer left-right universal compatibility, while select series incorporate a nail-pull non-adjustment design to boost operational efficiency. Complementing its functionality are four elegant color variants (Luxury Gold, Shining Silver, Moonlight Black, Phantom Gray), designed to harmonize with various decoration styles. Backed by exclusive patents and cutting-edge 18.5mm small shaft diameter technology, the product ensures high technical value and strong market competitiveness, standing out as a leading solution in the architectural hardware sector.

The Pioneering 18.5mm Pull-out No-adjustment Split-type Damping Hinge - **Innovative Pull-nail & No-adjustment Design**: Features a pull-nail type non-adjustable structure, making installation remarkably convenient and time-saving, eliminating the hassle of complex adjustments during setup. - **Industry-leading 18.5mm Pipe Diameter**: Breaks through industry limits with a pioneering 18.5mm shaft diameter. The smaller the shaft diameter, the higher the technical content, showcasing superior engineering and manufacturing capabilities. - **Adjustable Closing Force & Smart Door Control**: After the door is closed, the closing force is adjustable. It also has a functional angle design: the door automatically returns when opened to 160°, with a wind buffer zone from 80° to 20°, a silent locking zone from 20° to 0°, and an arbitrary door-holding zone from 160° to 80°, enabling precise and intelligent door movement control. - **Enhanced Performance & Durability**: Boasts smooth damping, quiet operation, and precise positioning. Its sturdy build guarantees long-lasting reliability, ideal for diverse door types and application scenarios.
