The spring resistance of suspension spring strictly are checked and controlled, and each batch performs the performance check of permanent deformation. Furthermore, we strictly control the height and stiffness of the spring.
|Classification||Cold rolling||Hot rolling|
1、The suspension coil spring is used to support car body, to relieve the vabriation by the uneven ground and keep tyre onto earth closely.
2、The material for suspension spring adopts high quality alloy spring steel 55CrSi after oil quenching.
3、Various testing for springs such as strength testing, crush test and endurance test to assure the high quality.
