Do you know the production process of hinges?
①Extrusion: This technique uses high pressurized force to compress the metal workpiece against a specially-shaped die. Extruded hinges tend to be stronger and thicker than stamped hinges, but are produced at a higher cost.
②Deformation: Deforming the metal into a hinge shape can involve bending, spinning, rolling, or forging it.
Drawing and deep drawing elongate the metal, stretching it until it attains a desired form,
while turret punching uses a sequence of dies that press against the workpiece to change its dimensions.
③Cutting: Removing excess material from the metal workpiece is another way to shape it into a hinge component.
This can be accomplished through sawing, shearing, drilling, or more sophisticated methods, such as laser and waterjet cutting.
After the main stages of production are complete,
there are numerous secondary and peripheral treatments that can be used to help with hinge wear or deterioration.
For example, every time a hinge is used a small percentage of its metal is worn away,
so some manufacturers opt for assembling hinge components with ball bearings between each joint.
These ball bearings allow a smoother glide when the hinge is in motion,
and they are a valuable addition to heavier doors or bulky hatches.
For aesthetic considerations, finishing treatments such as painting, burnishing, polishing,
or smoothing can increase a hinge’s decorative appeal, while rustproofing can help ensure the hinge
will have a longer and more efficient life as an integral component.
