How Spring Washer Works
the spring washer will produce a continuous elastic force to the nut after being flattened, so that the screw connection pair will maintain a continuous friction force! That is to say, spring washers prevent the loosening of the fastening bolt effectively caused by the vibration of the running equipment.
Main Process
1. All blank metal wire is subject to Pickling and Phosphetization to remove some rust on surface
2. After being cleaned, the metal wire will be stretched and deformed to square to get the accurate width and thickness
3. Then the square wire will be coiled to a certain inside diameter and be cut automatically 4. Gray washers will be heat treated
5. Surface Treatment
