Basic Concept: A continuous gear hinge is a special hinge that realizes continuous rotation or folding function through a series of intermeshing gears. This design enables the continuous gear hinge to keep stable and smooth movement when opening and closing, and at the same time can bear a large load, with a maximum weight capacity of up to 250kg.

Main Uses: Widely used in various occasions that need smooth rotation or folding, such as doors and windows, furniture, industrial equipment, and so on. It provides stable support and rotation functions, ensuring the normal operation of mechanical movement and a long service life.

Manufacturing Materials: Hinge manufacturing materials usually include stainless steel, copper, aluminum, and other metal materials, as well as plastic, nylon, and other non-metal materials. These materials have excellent mechanical properties and corrosion resistance to meet different requirements. Our continuous gear hinge is made of 6063 T5 aluminum alloy, which is waterproof, fireproof, and has strong corrosion resistance.

Preparation & Customization: Before production, detailed drawing design and material preparation are executed. Drawing designs include parameters such as the size, shape, and number of gears. We have five standard drawings and dies for continuous gear hinges, and customers can customize them based on their needs, including the size, length, and shape of hinges. We evaluate and simulate custom requests to provide feasible suggestions.

Gear Manufacturing: According to drawing specifications, we design new molds to ensure tooth profile and pitch accuracy. Aluminum alloy is extruded, cut, cooled, and aged in a furnace to enhance strength and hardness.

Hinge Assembly: The gears are assembled with close attention paid to meshing degree and rotation flexibility, ensuring stable and smooth movement. The gears are securely fixed to the main structure by drilling and screwing.

Surface Treatment: To improve corrosion resistance and aesthetics, surface treatments including anodizing and spraying are applied. This forms a protective film to prevent oxidation and enhance the appearance.

Quality Inspection: Complete hinges undergo strict quality inspections testing the gear bite, rotation flexibility, rotation cycles, and bearing capacity to ensure they meet strict design standards.

Debugging & Optimization: Any identified issues are addressed by adjusting the gear meshing and correcting hinge rotation flexibility to guarantee optimal performance before official usage.
