How is the Continuous Geared Hinge produced and processed, and what is its process flow?

The main production process of continuous gear hinge includes:

Blank forging: Forging metal materials into the initial shape of gears through hot die forging and other processes.

Normalization treatment: heat treatment of the blank to improve the cutting performance and comprehensive mechanical properties of the material.

Gear blank processing: CNC lathe is used to process the blank to ensure the size and shape accuracy of the gear.

Tooth profile processing: Tooth profile processing is carried out by gear hobbing machine or gear shaper to form the tooth profile of the gear.

Gear shaving and finishing: Gear shaving is carried out to improve the accuracy and surface quality of the gear, and then other finishing processes are carried out.

Heat treatment: Carburizing and quenching the gear to improve the hardness and wear resistance of the gear.

Grinding and testing: Grinding the gear to achieve higher accuracy and surface quality, and finally testing to ensure that the gear meets the design requirements.

Hinge extrusion: Aluminum alloy is extruded by die in extruder, and the strength and hardness of hinge are strengthened by cooling and aging treatment.

Hinge processing: Using CNC lathe to cut grooves and drill holes for hinges.

Stamping: Drill the hinge again in the CNC punch shop to make the aperture reach the appropriate size.

Assembly: in the assembly room, the gears and hinges are meshed with each other, and then assembled with other accessories, and the hinge is produced. Wipe the assembled hinge, and wipe off the residual cutting fluid and aluminium scrap on the surface. It is also necessary to anodize the surface to make it stronger and smoother. These steps together constitute the main production process of continuous geared hinge.
