Kitchen and bathroom functional cabinets: Aluminum-framed glass wall cabinets and base cabinets for kitchens, as well as aluminum-framed mirrored bathroom cabinets and bathroom vanities—designed to meet the demand for aluminum-framed door panels in the humid environments of kitchens and bathrooms.

Commercial display cabinet body: Commercial aluminum-frame display and storage cabinets, including jewelry showcases, cosmetics displays, and aluminum-framed office filing cabinets;

Cabinet with special-angle opening and closing: Aluminum-framed side cabinets and corner cabinets requiring small opening angles of 30°, 45°, or 90°, as well as aluminum-framed double-door cabinets and deep-body aluminum-framed cabinets requiring a large opening angle of 165°;

Cabinet bodies with different opening and closing requirements: For high-frequency opening and closing, the aluminum-framed cabinet is available with a single-stage force setting; for applications requiring smooth operation, a three-stage force setting is available; and for scenarios where items need to be held in mid-air, an adjustable two-stage force setting is offered.

Use value

Precise matching of aluminum-frame door panels to 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 during opening and closing that often arise 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 cabinet usability.

Damping cushioning + multi-stage force profile for an optimized opening and closing experience: Low-angle damping buffers ensure silent, impact-free door closing 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 dedicated 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 aluminum frame during installation and improving both installation efficiency and the yield of conforming 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 frame thickness of 18 mm, the clearance is 1.0–1.1 mm; for 19–22 mm, 1.0–3.5 mm; and for 23–26 mm, 2.7–5.1 mm. For the 165° wide-angle model with a frame thickness of 19–21 mm, the minimum clearance is 0 mm. Note that there are slight variations among different models and angles, so it is essential to match the clearance precisely according to the relevant product specification sheet.

Adjustment type

How do you adjust the height, cover position, and door gap using the adjustment screws on 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. For the three-dimensional adjustable cassette model, more precise multi-directional fine-tuning is possible.

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 can strip the threads or loosen the base. Once adjustment is complete, gently push the door panel to test its opening and closing; if no misalignment is detected, lightly tighten the adjustment screw or secure the base.

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 feature low-angle damping with a damping angle of less than 10 degrees. If the damping function fails, the following issues should be investigated first: ① Whether foreign matter such as dust or glass debris 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 their functionality due to wear and aging; since the damping cores in aluminum-frame hinges are typically integrated, any damage requires 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-section force spring assembly due to foreign objects or insufficient lubrication; in this case, remove 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 Loosening of the hinge mounting, with the base or screws not fully secured, causing displacement of the door panel during operation; re-tighten all components and make minor adjustments.
