iron material 40 cup four-hole hinge factory direct supply tooling home decoration bulk purchase high price hardware

The hinge features a 40mm large-diameter standard cup body design, which has been precisely calculated to fit thicker door panels and heavier cabinet bodies. Its bearing capacity exceeds that of conventional small-diameter hinges. The cup body is firmly connected to the hinge arm, ensuring even distribution of force and stable support for various medium and small-sized furniture door panels, preventing sagging or detachment due to excessive door panel weight. It meets the weight-bearing requirements of multiple scenarios. Equipped with a standard four-hole fixed base, the hole positions are evenly distributed and symmetrical, ensuring scientific distribution of the load points. After locking with self-tapping screws, it tightly adheres to the cabinet side panel, effectively solving the problem of looseness or displacement caused by frequent door opening and closing over time. The connection stability exceeds that of hinges with two-hole bases. After installation, it can withstand high-frequency operation, suitable for family use and mass production assembly scenarios. The hinge body is made of high-toughness cold-rolled iron sheet, which is stamped into one piece without welding points or burrs, ensuring compact structure and impact resistance. The surface is treated with anti-rust spray painting, resistant to moisture and dust erosion in daily environments, making it less prone to rusting or deformation over long-term use. It meets the basic usage requirements of ordinary home decoration, renovation of rental apartments, and mass production of the workplace, with outstanding cost-performance.
