Use value

Precisely matched aluminum-frame door panels enhance cabinet fit: As a dedicated accessory for aluminum-framed door panels, these hinges are precisely engineered to match the drilling patterns, thickness, and width specifications of aluminum frames, thereby eliminating common issues such as looseness, misalignment, and sticking that often occur when using standard hinges on aluminum-framed doors. This enhances the overall aesthetic quality and premium feel of aluminum-framed cabinets.
A wide range of specifications to meet all opening and closing requirements: comprehensive options for structure, angle, and actuation force allow precise customization based on the aluminum-frame cabinet’s application scenario, installation location, and specific opening/closing needs, enabling standard opening, special-angle opening, and hover-opening configurations to deliver personalized solutions and enhance user convenience.

Damping cushioning + multi-stage force profile for an optimized opening and closing experience: Low-angle damping buffers ensure silent, impact-free door closure and prevent pinching, while the three-stage force adjustment feature delivers smoother opening and closing of aluminum-framed door panels—eliminating wobbling and potential breakage of glass-aluminum doors. The free-stop function allows the door panel to pause at any position, making it easy to access items stored deep inside the cabinet and significantly enhancing the overall user experience of aluminum-framed cabinets.

Three-dimensional adjustment feature reduces installation and after-sales costs: Multi-dimensional adjustment allows for correction of installation misalignment between the aluminum-frame door panel and the cabinet body, eliminating the need to re-drill holes for alignment. In the course of subsequent use, if the door panel becomes misaligned or the door gaps are uneven, it can be directly fine-tuned and repaired, thereby extending the service life of the hinges and the aluminum-frame cabinet body and reducing after-sales maintenance costs.

Multi-color surface treatment that balances practicality and aesthetics: Four surface finishes—nickel plating, gunmetal, gold, and black—can be precisely matched with aluminum-framed door panels in various colors and styles, seamlessly integrating hardware accessories with the cabinet body to enhance the overall aesthetic appeal and understated luxury of aluminum-framed furniture.

Dedicated accessories and optimized installation processes enhance installation efficiency: Equipped with exclusive mounting accessories for aluminum-framed door panels, the snap-in quick-install design significantly reduces installation time, while the fixed-mount version ensures stable connections. The installation process is fully tailored to the material properties of aluminum-framed door panels, preventing damage to the frame during installation and improving both installation efficiency and the yield of qualified finished products.

Frequently Asked Questions

Installation type

How is the 28 mm drilling position determined for aluminum frames? Does the drilling position vary depending on the frame’s thickness and width?

Answer: The 28 mm aluminum-frame drilling is a standardized specification across the entire product line. The drilling positions must be determined in accordance with the accompanying Cover-Position Calculation Table (Table D) and Gap-Position Calculation Table (Table A), based on the aluminum-frame thickness (T value), width (W value), and cabinet type (full-cover / half-cover / internal concealment). For aluminum frames of different thicknesses or widths, only the corresponding gap parameters need to be matched; the drilling diameter remains fixed at 28 mm, and the core drilling position does not require adjustment.

What is the minimum door opening clearance for different aluminum frame thicknesses and widths?

Answer: For aluminum frames with a thickness of 18–26 mm and a width of 19–26 mm, the corresponding minimum door-opening clearance ranges from 0.1 to 5.1 mm. The key reference values are as follows: for a 18-mm-thick frame, the clearance is 1.0–1.1 mm; for frames 19–22 mm thick, 1.0–3.5 mm; and for frames 23–26 mm thick, 2.7–5.1 mm. For the 165° wide-angle model, the minimum clearance for frames 19–21 mm thick is 0 mm. Note that there are slight variations among different models and opening angles; therefore, precise matching must be based on the relevant product specification sheet.

Adjustment type

How do you adjust the height, cover position, and door gap, and how do you operate the base?

Answer: ① Height adjustment: Fine-tuning is achieved via a dedicated base mounted on the cabinet side panel, allowing for ±1.5 mm adjustment in the vertical direction; ② Lid position/door gap adjustment: By rotating the adjustment screw at the corresponding hinge location, the lid position can be adjusted by up to +5 mm, and the door gap by up to +2.5 mm; ③ Leveling/depth adjustment: Directly rotate the leveling/depth adjustment screw on the hinge to increase or decrease the setting as needed. The three-dimensional adjustable cassette model enables even more precise multi-directional fine-tuning.

How can excessive adjustment during the adjustment process be avoided to prevent misalignment of aluminum frame door panels and loosening of hinges?

Answer: Aluminum-framed door panels are often paired with glass. When making adjustments, follow the principles of small, incremental tweaks combined with real-time inspection: for every 1/4 turn of the adjustment screw, check the fit between the aluminum-framed door panel and the cabinet body as well as the uniformity of the door gap, to prevent the glass door from being squeezed and broken due to improper adjustment. At the same time, avoid over-rotating the adjustment screw, which could strip the threads or loosen the base. Once adjustment is complete, gently push the door panel to test its opening and closing; only after confirming there is no misalignment should the adjustment screw or base be lightly secured.

Using classes

How should one troubleshoot when the low-angle damping buffer function (less than 10 degrees) fails?

Answer: Several models of aluminum-frame hinges are equipped with low-angle damping buffers rated for angles less than 10 degrees. If such a hinge fails, the following issues should be investigated first: ① Whether foreign matter such as dust or glass fragments has entered the damping core, causing the damping components to seize; if so, remove the contaminants and retest. ② Whether the aluminum-frame door panel is misaligned during installation, thereby compressing the damping mechanism; in this case, slightly adjust the hinge position to relieve the pressure on the damping components. ③ Whether the damping components have lost functionality due to wear and aging; since the damping cores in aluminum-frame hinges are typically integrated, any damage necessitates replacing the entire hinge assembly.

What causes the three-section, force-type aluminum-framed door panel to open and close unevenly and with a sticking sensation?

Answer: The main causes include: ① Sticking of the three-stage force spring assembly due to foreign objects or insufficient lubrication; clean out any foreign matter and apply hardware-specific grease. ② Deviation in the installation angle of the aluminum frame door panel, resulting in uneven forces during opening and closing; adjust the installation position by fine-tuning the horizontal and depth adjustment screws. ③ Loose hinge mounting—failure to fully tighten the base or screws—causing door panel displacement during operation; re-tighten all components and make minor adjustments.
