1.Raw material selection: Select materials suitable for nut production, common materials include carbon steel, stainless steel, aluminum alloy, etc.
2.Material processing: Processing and processing selected raw materials, including shearing, cold forging, or hot forging processes, to achieve the required shape and strength of the material.
3.Thread processing: By machining processes such as turning, milling, and drilling, the outer cylinder of the nut is processed into an inner hole with a certain thread. This step usually requires the use of specialized thread processing machines.
4.Heat treatment: Heat treat the nut to improve its hardness and strength. The methods of heat treatment can be quenching, tempering, etc.
5.Surface treatment: Treat the outer surface of the wheel nut to improve its smoothness and anti-corrosion performance. Common surface treatment methods include galvanizing, nickel plating, spraying, etc.
6.Quality inspection: Conduct quality inspection on nuts to ensure that their dimensions, threads, and mechanical properties meet the requirements. Common inspection methods include appearance inspection, size measurement, thread inspection, etc.
7.Packaging and delivery: Nuts that have passed the inspection shall be packaged and prepared for delivery.
