The Process Flow Of Hexagon Socket Head Bolt
China Stud Supplier has a wide range of product categories. Broadly speaking, connectors, transmission parts, hydraulic components, pneumatic components, bearings, etc. are all covered. Users can choose different specifications according to their own needs, the weight of the objects that need to be connected and fixed. Fasteners are used. In order to ensure the quality of parts, standard parts manufacturers are improving the production process year by year, keeping up with the pace of development of the times, today I will summarize the production process for everyone?
Pan Yuan: refers to the wire you bought
Annealing: refers to increasing the hardness of the wire itself. (This process is also more important. Now all high-temperature spheroidizing annealing furnaces are used)
Pickling: to wash away the rust and impurities on the surface of the wire
Wire drawing: refers to drawing the wire to the diameter you need to produce the bolt
Heading: It is the head of the bolt extruded by cold heading. (If it is a bolt above M20, it needs to be hit with red, that is, it needs to be heated before hitting the head, but the surface of that bolt is not very beautiful, because there is oxide skin)
Tooth rolling: refers to the required pitch and tooth type
Heat treatment: This process is more important to determine the performance level of the bolt
Electroplating: Treat the surface to the required surface color
The above is a summary of the production process that is commonly used in Hexagon Socket Head Bolt, and the role played by each link is also listed in detail for everyone, which will not only enhance everyone’s understanding of how fasteners are. Produced, at the same time, the qualification of the manufacturer can also be reviewed, so as to ensure that the quality of the cooperatively purchased parts meets their own standards for use.
