The 3D Adjusting Door Hinge is a precision hardware connection device featuring multi-directional adjustment capabilities. Its core mechanism employs a unique screw system and sliding components to achieve precise positioning of the door within three-dimensional space. This product permits independent adjustment in three directions – vertical, horizontal, and depth – after installation, with adjustment precision reaching millimetre level. Featuring a concealed design, this hinge remains entirely hidden within the door leaf and frame when closed, preserving the visual integrity of architectural spaces. Its manufacture complies with the mechanical performance specifications of EN1935 standards for hinges, requiring specialised positioning tools during installation to ensure slot precision. The three-dimensional adjustment capability is particularly suited to high-standard engineering applications where accommodating structural movement or installation tolerances is essential.

Product Features
1. Exceptional Durability
This 3D adjustable door hinge has passed the EN1935 certified 200,000-cycle test, equivalent to over 25 years of daily use. Its zinc alloy die-cast body boasts high tensile strength, far exceeding the mechanical properties of standard hinges. The connecting plates utilise aluminium alloy for robust durability. Stainless steel cover plates provide additional protection. This hinge is particularly suited for high-traffic public spaces, offering a service life exceeding standard products by over three times, ensuring long-term maintenance-free operation.
2. Exceptional Fire Resistance
Certified to EN1634 with a 132-minute fire rating, exceeding standard fire door requirements. Features a composite fire-resistant structure: 304 stainless steel cover plate withstands 1000°C temperatures; integrated expanding graphite seal expands upon heating to form an effective barrier; all fasteners treated with ceramic fire-retardant coating. This 3D adjusting door hinge maintains structural integrity under extreme conditions, providing critical assurance for personnel evacuation with fire resistance performance at the forefront of international standards.
3. Precision Adjustment
Enables three-dimensional fine-tuning:
- Vertical adjustment: ±2.2mm to correct sagging door panels
- Horizontal adjustment: ±1.8mm to eliminate uneven gaps
- Depth adjustment: ±1.5mm to ensure flush door surfaces All adjustments are performed using a dedicated hex key, achieving precision down to 0.08mm. This 3D adjusting door hinge effectively compensates for building settlement and deformation, maintaining optimal door performance while significantly reducing installation and commissioning complexity.
4. Superior Corrosion Resistance
Certified to EN1670 Class 5, exhibiting no corrosion signs after 48 hours of salt spray testing. Featuring multi-layer electroplating, this hinge is particularly suited for high-humidity environments and coastal regions, ensuring long-term aesthetic and functional integrity.
Product Applications
1. Premium Commercial Complexes
Large shopping centres endure heavy footfall, demanding exceptional door durability and aesthetics. This hinge, certified for 200,000 cycles of endurance testing, withstands intensive use. Its concealed design maintains visual clarity, while three-dimensional adjustment swiftly corrects displacement caused by pedestrian impact. Fire-rated performance meets public building safety standards, making it ideal for commercial premises.
2. Healthcare Institutions
Hospitals and clinics demand stringent hygiene standards and door reliability. This product provides 132 minutes of fire resistance, with a surface finish resistant to disinfectant corrosion. Precise three-dimensional adjustment ensures a tight seal between door leaf and frame, effectively maintaining indoor pressure differentials. The concealed design eliminates hygiene dead zones, meeting infection control requirements for medical facilities. It is particularly suitable for operating theatres and cleanroom environments.
3. Educational and Research Facilities
Schools and laboratories require secure, dependable door solutions. This 3D adjusting door hinge meets educational institution safety standards for fire resistance, with durability testing ensuring long-term reliability. Its three-dimensional adjustment compensates for building settlement, maintaining door leaf alignment. The concealed design prevents student collisions, reduces maintenance costs, and represents a prudent choice for educational establishments.
