Model WN-MF4-HC is a standard 4-inch split damping hinge. The product comes in four mainstream anodized colors: matte black, luxury gold, deep space silver, and shadowy gray. It continues the brand's oil-free split spring-driven structure, completely solving the problems of oil leakage and buffer failure in traditional hydraulic hinges. The damping module can be disassembled and replaced separately to reduce maintenance costs. The two-stage closing force can be freely adjusted, providing a rich range of appearance options that can match modern, minimalist, new Chinese style, and luxury interior designs. It offers standardized hinge products that combine both appearance and performance for door manufacturers.

The four-part split damping hinge combines an innovative four-part structure, integrating four common products - the hinge, door stopper, door pull, and positioning device - into a single hardware component. The product can freely switch between one-stage and two-stage closing force, and also has multiple functions such as door panel buffer closing, opening angle positioning, and automatic limit to prevent bumping. It retains the oil-free split structure to eliminate the problem of oil leakage, significantly simplifies the installation process of wooden doors, reduces the cost of purchasing scattered hardware components, and provides a highly integrated one-stop hinge solution for home decoration wooden doors and batch production of engineering doors.
