Manufacturing梅花shape bolts requires fixed equipment and machine tool processing. Of course, the processing program is relatively simple, mainly consisting of the following steps: Firstly, the material needs to be pulled straight using a pulling machine. This step is necessary before proceeding to the next one. The next step involves cutting the pulled, long material to the required length per customer specifications using a cutting machine. This completes the second step. The third step is to place the cut short material on a rolling machine to form the thread. At this point, the standard梅花-shaped bolt is finished. Of course, if other requirements are needed, additional steps are required.
