Manufacturing process for passenger car nuts

The manufacturing process of passenger car nuts usually includes the following steps:

Material selection: Choose appropriate materials, such as carbon steel, stainless steel, etc., and select according to the use and requirements of the nut.

Cold forging: The selected material is cold-forged to deform it into the shape of an approximate nut.

Heat treatment: the cold forged nut is heat treated to improve its strength and hardness, as well as to eliminate internal stresses.

Turning:  Heat-treated nuts are turned to achieve precise dimensions and shapes.

Surface treatment: such as plating, etc., to improve corrosion resistance and aesthetics of the nut.

Quality inspection: the manufactured nuts are quality inspected to ensure they meet the standard requirements.
