1.Raw material thermal treatment：

Firstly , we need to know the hinge manufacturing involves a certain degree of thermal treatment,the raw metal material will firstly heated to make it molten in a smelting unit,for the purpose of forming into various shapes and change its chemical composition.

2.Casting:

The casting is an important machining working step, during the casting process , the metal is melted and then put into the mold to solidify the determined form. After casting , the pieces will be under finishing treatment to have an aesthetic feature.

3.Extrusion:
Extrusion is a working technique that can force the metal against a specially shaped die under high pressure. The extruded hinges are usually stronger in mechanical property than stamped hinges.

4.Deformation:
Deformation of metal into a certain hinge shape is a complex process, that include bending, spinning, rolling, or forging it.The metal needs to be drawn and elongated , and stretched until it obtain a desired form.

5.Cutting:
Removing excess material  from metal workpiece is another way to shape it into a hinge component. The cutting is usually accomplished by sawing, drilling , or shearing or laser and waterjet cutting.

6.Secondary production process of hinges:
The secondary production process involves treatment for protection against deterioration and wear.Every time a hinge is used,some of its metal is worn away. Thus some manufacturers will assemble hinge with ball bearing in the middle of each joint.The ball bearings ensure a smoother glide when the hinge is in motion, while for aesthetic consideration, the hinges before sending to customers , will also have a series of finishing treatments such as polishing, burnishing , painting to increase  decorative appeal.
