bought out components, to in process controls and the finished product.
The raw material is insp- ected heat wise to ensure the quality of material for mechanical as well as metallurgical paramet- ers, including chemical analysis and macro etching in a well equipped laboratory. The material aft- er Heat treatment is once again tested for tempered martensite structure and surface decarburisa- tion by micro etching. ILS adopts a stringent Quality Control System for incoming inspection of Raw Materials and other Bought Out Components such as Center Bolts, Nuts, Spring Eye Bushes etc. All our out - sourced material is procured from highly reputed Vendors. In process controls are designed to ensure product quality at every stage of manufacture. Stringent inprocess control ens- ures that manufacturing activities are carried out effectively and without disruptions. Every single work area has documented work instructions and is inspected accordingly. |

The
finished springs are checked for load rate
on a sample basis. A Load Testing machine ensures that the springs are
manufactured to withstand certain loads in accordance with the specifications
laid down in the original drawing.
The
springs are further subjected to an endurance test on an Endurance Testing
machine to determine the fatigue life of
the spring. A fatigue life of 1,00,000 cycles is considered adequate and
represents a life of 1,60,000 kms on 'ON HIGHWAY' operation.
