Collection: 3D Concealed Hinges

A 3D Concealed Hinge (often called a fully adjustable hinge) is the premium category of cup hinges. The "3D" refers to its ability to adjust the door panel in three independent planes after installation:

• Depth Adjustment (In/Out): Compensates for door panel thickness variations or ensures the door sits flush with the cabinet frame.
• Height Adjustment (Up/Down): Corrects minor discrepancies in the drilling position of the cup hole.
• Side/Lateral Adjustment (Left/Right): Fine-tunes the gap between doors for a perfectly even reveal.

A standard concealed hinge typically only offers 2D adjustment (height and depth, or side-to-side and depth). The 3D version provides ultimate installation flexibility and precision, essential for flawless mass production and high-end custom work.

The key benefits are precision, efficiency, and durability:

• Perfect Alignment: Compensates for cumulative tolerances in cabinet boxes and door panels, ensuring consistent, professional-looking gaps.
• Faster Installation & Corrections: Installers can quickly fine-tune doors on-site without remounting the hinge base, saving significant labor time and reducing callbacks.
• Integrated Soft-Close: Most 3D hinges include a hydraulic or mechanical soft-close mechanism, ensuring doors close quietly and gently every time—a must-have for modern residential and commercial furniture.
• Superior Weight Capacity & Longevity: Engineered for heavier doors and high-frequency use, with robust steel construction and high-cycle testing.

• Standard Finishes: Nickel (Satin & Polished), Black, Dark Bronze. These are applied via electroplating or PVD coating for superior scratch and corrosion resistance.
• Custom Finishes: For large-volume projects (OEM/ODM), we offer custom PVD colors (e.g., Matte Black, Brushed Gold, Chrome) to match your hardware exactly.

Our hinges undergo strict quality checks:

• Cycle Testing: Hinges are tested to exceed 80,000 to 100,000 open/close cycles.
• Salt Spray Test: Finishes are tested for 96 hours of corrosion resistance.

 We cater to both small studios and large manufacturers:

• Packaging: Standard is a white regular package for cost-efficiency.
• MOQ (Minimum Order Quantity): Relatively 300 for standard items. For custom finishes or packaging, a higher MOQ applies. Contact us for specific terms.
• Samples: We provide functional samples for testing and approval before full production runs.
