Hidden Door Hinge is a special hardware accessory that hides the hinge body at the connection between the door frame and the door leaf. Its design breaks through the visual limitations of traditional exposed hinges, and through precise structural layout, the hinges are fully embedded inside the door body, retaining only necessary movement clearance. This design not only achieves a seamless appearance when the door is closed, but also enhances the overall beauty and safety of the building space through physical concealment. As an important innovation in the field of modern architectural hardware, Hidden Door Hinge achieves stable support and flexible rotation of the door leaf through a precise mechanical structure. Its core structure includes a hidden axis, three-dimensional adjustment components, and high-strength connecting parts. While maintaining functional integrity, it completely changes the visual presentation of traditional hinges.

Core features of the product
1. Three dimensional precise adjustment
This hidden door hinge adopts an EN1935 certified 3D adjustment system, which supports precise fine adjustment of ± 3mm in the vertical direction, ± 2mm in the horizontal direction, and ± 1.5mm in the depth direction. By independently adjusting the screw design, the installation personnel can complete all parameter calibration in the closed state of the door leaf, ensuring that the uniformity of the door gap is ≤ 0.5mm. After 200000 cycles of testing verification, the adjustment mechanism maintains zero looseness, perfectly meeting the requirements of EN1935 standard for long-term stability.
2. Super strong fire resistance performance
The product has passed the EN1634 fire test and maintained structural integrity for 132 minutes in a high temperature environment. Zinc alloy substrate, combined with special fireproof coating treatment, effectively blocks the spread of flames. The hidden design avoids the risk of door leaf detachment caused by high temperature deformation of traditional hinges, providing dual safety protection for wooden fireproof doors and meeting the performance requirements of fireproof doors.
3. Excellent anti-corrosion ability
According to the EN1670 standard 48 hour neutral salt spray test, there are no signs of corrosion on the surface of the product. The zinc alloy body adopts die-casting technology, combined with 304 stainless steel decorative cover to form dual protection. The surface treatment adopts a combination of matte black baking paint and brushed stainless steel cover plate, which can maintain rust prevention performance for more than 10 years in humid environments.
Typical application scenarios
1.High end residential entrance door
In villas and large flat projects, Hidden Door Hinges can be perfectly hidden within wooden door frames, combined with intelligent door lock systems to create a minimalist design without handles. Its three-dimensional adjustment function ensures that the door weighing up to 40kg maintains long-term stable operation, and its 48 hour anti-corrosion performance adapts to high humidity coastal environments, making it the preferred safety accessory for high-end residences.
2.Five star hotel room door
The product's ultra quiet feature ensures that the opening and closing noise of the door leaf is lower than the background noise of the guest room, avoiding disturbing guests' rest. The hidden design eliminates the safety hazards caused by traditional hinge exposure, and meets the requirements of hotel fire safety regulations with fire certification. The matte black color scheme seamlessly blends with various decoration styles to enhance the overall quality of the space.
