Door Hinges Manufacturer In China
Door hinges are the core hardware components that connect the door body and the door frame. They enable the door to open and close smoothly through a rotatable mechanical structure. Its basic structure includes interlocking leaves, a central axis and a bearing system. They are widely used in building doors and windows, furniture cabinets and industrial equipment. They must meet performance requirements such as load-bearing tests and fatigue tests. Their accuracy directly affects the verticality, quietness and service life of the door leaf.

Door Hinges
Features Of Door Hinges
As the core component connecting the door body and the door frame, the door hinge has the characteristics of high strength, wear resistance and precise positioning. Its main body is usually made of cold-rolled steel, stainless steel or zinc alloy to ensure resistance to deformation and corrosion during long-term use. Structurally, it is divided into fixed leaves (connecting the door frame), movable leaves (connecting the door body) and rotating shafts. Some high-end products are equipped with ball bearings or hydraulic buffer devices to achieve silent opening and closing and automatic closing functions.
Material Of Door Hinges
The choice of raw materials for door hinges directly affects their load-bearing capacity, corrosion resistance and service life. The current mainstream materials include cold-rolled steel (SPCC), stainless steel (304/316), zinc alloy (such as ZA-8) and copper alloy (H59 brass). Cold-rolled steel is low-cost after galvanizing or chrome plating and is suitable for ordinary indoor environments; 304 stainless steel contains 18% chromium and 8% nickel, is resistant to salt spray corrosion, and is suitable for humid places; zinc alloy die-casting is suitable for complex shapes but has limited load-bearing capacity; brass has both antibacterial properties and aesthetics, and is mostly used in high-end places.

Key Applications of Ninesuns Door Hinges
Door hinges are the core components that connect door bodies and door frames and are widely used in the fields of construction, furniture, industrial equipment, etc. In residential and commercial buildings, ordinary steel hinges support the daily opening and closing of interior doors, while stainless steel hinges have become the standard in humid environments such as bathrooms and kitchens due to their corrosion resistance; brass hinges are often used in high-end places to take into account both load-bearing and decorative effects. The furniture industry relies on hidden hinges to achieve seamless opening and closing of cabinet doors, while heavy industrial doors use hinges with bearings to withstand frequent high-load operation.
