For large quantities of hardware parts, cold forming is the preferred method.

The cold forming process can save material, achieve fast production speed, and ensure high product strength. For large-volume products, cold forming is the preferred processing method. It produces a blank, which is then further machined by turning to achieve the required shape and precision. Heat treatment may be applied to improve hardness and wear resistance, followed by surface treatments such as electroplating for rust prevention.
