[0002] At present, after the spring is manufactured, it is necessary to test the various properties of the spring, such as load test at a specified height, permanent deformation test, fatigue life test, and sometimes special performance test is required by customers. Before use, it must pass strict tests before it can be put into use. Because some springs are used in more important occasions, there are strict requirements for each product used, such as vehicles, weapons, etc. If the requirements of the spring are not met, the spring will break or plastically deform during use, which is likely to cause a major accident.
