The first link is the disk element, which is to find out the factory disk, product name, specification, material, weight and quantity according to the actual requirements, and then go to the manufacturer to buy the appropriate wire rod. It is worth noting here that the content is not high. will be better. Not only to reduce costs, but also to make
screws better in the subsequent process.
The second link is annealing. Annealing is to increase the forging performance of the screw, which is beneficial to its later processing.
The third link is pickling. Pickling refers to treating the surface of the screw so that we can proceed more smoothly in the next step.
The fourth step, draw the line. Thread-drawing is the closing step for the previous pickling step, which is indispensable.
The fifth step is to start. It is to punch out the head of the screw to form the shape of the screw. Heading is very important, a screw has a perfect head and shape, giving customers a completely different feeling of use. Therefore, we often encounter the situation that the screw head is bad. At this time, we are required to know the reasons for the bad head of the screw when we produce the screw.
The sixth step is the operation of rubbing teeth. The thread rolling process for screwing the basic screw is very important. A regular screw with guaranteed quality must pass the test of this step so that it can pass the stop gauge.
The seventh step is heat treatment. It is essential that the screws retain their mechanical properties only after heat treatment.
The eighth step is electroplating. The electroplating process is generally proposed by the customer and the corresponding surface treatment is carried out. It is also important to maintain the aesthetics of the screw surface.
