Bharat Spring supplies quality springs to chassis manufactures of Buses, Trucks, Trailers, Cars and Special vehicles. The initial stages in Leaf spring manufacture are: * Cutting of Spring steel Flats into required sizes * Punching of the center hole * End-cropping * Tapering of leaves * Eye-rolling After these stages the leaves are ready for heat-treatment. This includes annealing, straightening and tempering. The leaves are shot-peened, which operation creates a surface tension, an improves fatigue strength. Before fitting the bushes, the eye of the main leaf will be bored to close tolerance. The leaves are then ready for assembly.
