Manufacturing process:

Shearing and drilling operations are done on spring steel-flats. Flats for top springs are sheared in four corners; both the ends are heated and rolled into formation of eye. Steel flats are heated, given the required camber (in hot condition) for specific shape depending on the position of the flat in the spring and quenched in oil. After hardening, these are again heated for tempering. Shot blasting operation carried out on the hardened &tempered spring flats. Subsequently various tests like Hardness testing, Camber tests are carried out.
