Ekatamotors the best leaf spring supplier in Bangladesh

Our product are 100% shot-peened. 

This process specifically designed to enhance the fatigue strength of Spring. Surface treatment procedures like grinding, milling, bending or heat treatment procedures cause Tensile Residual Stress. This Tensile Residual Stress leads to low life cycles of the spring. Shot Peening converts Tensile Residual Stress into Compressive Residual Stress which leads to significant increases in the life cycle of parts like leaf spring and their maximum load capacities. Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of metals. It entails impacting a surface with shot (round metallic, glass, or ceramic particles) with a force sufficient to create a plastic deformation.

Shot peening delay or prevention of cracks in highly tensile stressed parts like leaf spring. We can alter these undesirable manufacturing and operational tensile stresses to life-enhancing residual compressive stresses, therefore, extending spring life.

The process works by introducing the residual compressive stress in the surface of the spring. The compressive stress helps to prevent crack initiation as cracks cannot propagate in the compressive environment generated by peening.
