OEM Door Hinges.Customized forging.Forged Door Hinge.

Forged hinge is a mechanical device used to connect two solids and allow relative rotation between them. The hinge can be composed of movable components or foldable forged items.

Forged hinges have high strength, good toughness, and are less possible breakage when collisions, providing a better connection between the car door and the car body.
 
The national standard for hinges requires that the door hinge can withstand a longitudinal load of 11.11KN and a transverse load of 8.89KN without detachment.
 
Gernerally,the raw material for forged hinges should be have good welding properties like Q355B.
