Top Trusted Concealed Hinges Suppliers & Exporter

For standard off-the-shelf hydraulic soft-close cabinet hinges (such as standard nickel-plated 105° or 165° clip-on models), our minimum order quantity starts as low as 44 to 200 pieces for initial quality and fit validation. For bespoke OEM orders requiring custom laser logo engraving on the hinge arm, customized stamping cup profiles, or branded color polybag/box packaging, the MOQ standard is generally 1,000 to 5,000 pairs. We also support container-level consolidation where multiple SKUs can be bundled together to meet production economic scale.

Our hinge testing protocols comply strictly with European Standard EN 15570 (Hardware for furniture – Strength and durability of hinges and their components) Level 2 and Level 3, as well as ANSI/BHMA A156.9. Products are mounted onto test fixtures replicating realistic door mass and dimensions, undergoing continuous automated opening and closing cycles at a velocity of 20±2 cycles per minute. Standard lines achieve 50,000 cycles, while premium residential and commercial lines withstand 80,000 to 100,000 uninterrupted cycles with zero mechanical failure, excessive sagging under 1.5mm, or damping cylinder oil leakage.

The overlay designation determines how the cabinet door leaf relates to the cabinet carcass side panel (gable). Full Overlay (Straight Arm / 0 Crank): The door completely overlaps the carcass edge, leaving only a tiny edge margin (typically covering 15–19mm of an 18mm side panel). Half Overlay (Half Bent / 8mm Crank): Used when two adjacent cabinet doors share a single center partition panel; each door covers approximately half the panel width. Inset (Full Bent / 17mm Crank): The door panel sits fully flush inside the carcass opening, exposing the outer frame of the cabinet carcass.

For standard residential furniture in climate-controlled environments, our automated electro-galvanized cold-rolled steel hinges feature multi-tier copper-nickel plating passing 48 to 72 hours in a standard 5% Neutral Salt Spray (NSS) chamber (ISO 9227 / ASTM B117). For coastal areas, commercial kitchens, luxury bathrooms, or exterior marine cabinetry, we manufacture full austenitic SUS304 or SUS316 stainless steel hinges. SUS304 units withstand 96 to 120 hours of NSS testing without red rust formation. Additionally, we provide advanced PVD (Physical Vapor Deposition) and electrophoretic coatings in matte black, gunmetal, and brass finishes.

Yes. One of our primary competitive advantages is our integrated supply chain ecosystem spanning over 50 verified factories. Importers frequently consolidate concealed cabinet hinges, undermount and ball bearing drawer slides, pull-out pantry baskets, 304 stainless steel kitchen sinks, wardrobe lifts, and architectural door handles into one cohesive shipment. Our centralized warehouse in Xiamen coordinates incoming inspections, palletizes according to container loading optimization software, and arranges single-bill-of-lading (B/L) export customs clearance.

Hinge allocation is governed by door height, door width, panel thickness, and total door weight (including facade accessories and handles). General engineering recommendations: Doors up to 900mm in height and weighing under 6kg require 2 hinges; doors 900mm to 1600mm (6–12kg) require 3 hinges; doors 1600mm to 2000mm (12–17kg) require 4 hinges; tall doors 2000mm to 2400mm (17–22kg) require a minimum of 5 hinges. For wide doors exceeding 600mm in width, the kinematic leverage increases, requiring an additional hinge to maintain horizontal stability and prevent pivot axis warping.
