Wooden doors, as one of the oldest architectural components, are always looking for a balance between natural texture and artificial techniques - it not only has to convey the warm touch of wood, but also has to withstand the physical challenges of high-frequency use: sagging door sashes, rattling hinges, and cracked screw holes. ......
When the traditional hinge “squeak” sound breaks the silence, when the door gap error destroys the purity of minimalism, a precision revolution for the wooden door quietly came. Hydraulic Door Closer Hinge, a technology once reserved for heavy metal doors, is a cross-domain fusion of material science and mechanical engineering to redefine the value dimension of wooden doors.
The mission of wooden door hinges The problems we face
The demand for hinges for wooden doors is much more than just “being able to turn”. The core challenge stems from the natural properties of wood:
Solid wood doors: uneven density (e.g. walnut ≈ 640kg/m³, pine ≈ 450kg/m³), easy to bend and deform under long-term gravity, hinges need to provide continuous anti-sagging force.
Composite door: the difference in thermal expansion coefficient between core material (honeycomb paper/density board) and surface veneer requires hinges with micron-level displacement compensation capability.
Material Dialog Requirements
The surface treatment of the hinge needs to be symbiotic with the wood grain style (matte black/brushed bronze) to avoid the metallic texture destroying the natural aesthetics.
The design of screw holes must be adapted to the direction of wood fibers to prevent cracking caused by stress concentration.
Sensory experience upgrade
The opening and closing noise should be ≤30dB (equivalent to the ambient sound of the library), eliminating the metal friction sound of traditional hinges.
The closing trajectory should simulate natural damping, avoiding the abrupt stop of mechanical sense.
Aleader wooden doors are adapted to various requirements, realizing a precise balance between force and beauty.

Core Advantages
Intelligent cushioning
Hydraulic damping system realizes “buffer at touch”, the door opens and closes quietly, bidding farewell to impact noise.
The closing speed at the end is automatically reduced to 0.3m/s, preventing the door from hitting the door frame and protecting the door structure.
Windproof and shockproof, stable and durable
Special hinge structure + high-precision hydraulic oil circuit to resist door shaking in strong wind environment and avoid accidental closure.
Resistant to humidity, temperature difference and other complex environments, corrosion-resistant life increased by 50%.
Convenient installation
The product does not need to distinguish between left and right opening, which is very user-friendly, saves labor and is easier to adjust. All rotating parts are connected with bearings, quiet, efficient and durable.
Maximum tolerance values
Maximum door weight 90 kg
Maximum door height ≤ 2400 mm
Maximum door width ≤1200mm
Door thickness 40-60mm
Concealed hinges (M9/M10 series): let the door become a space magician
Design positioning: for the high-end market, with minimalist aesthetics and intelligent adjustment as the core, redefining the relationship between the door and the wall.
M9 series invisible door system - a technical model of precision adjustment and structural integrity
One-piece cantilever design
Adopting the world's first cascading damping integration technology, the load-bearing hinges and cushioning system are integrated into the unilateral structure, realizing the minimalist visual effect of zero exposure of the door opening and closing.
Fully embedded structure: the hinges are completely hidden in the door frame, leaving only 0.3mm micro-adjustment holes on the surface.
Three-dimensional tolerance compensation mechanism
Vertical compensation: ±2.5mm floor height error is automatically corrected.
Horizontal compensation: ±2.5mm wall tilt adjustment.
Depth compensation: ±2.5mm wall flatness adaptation

Make every door, a ritual to the ideal
In Aleader's belief, hinges are not only mechanical components, but also translators of spatial emotions.
Choosing Aleader means choosing an uncompromising way of dialog-
Dialogue with wood, guarding the breath of wood grain with the precision of aviation aluminum;
Dialogue with time, fighting physical entropy increase with 200,000 cycle life;
Dialogue with human nature, with anti-pinch force ≤ 12N gentle against the coldness of industry.
We don't make hinges, we only create the ultimate tacit understanding between door and space.
