The manufacturing process is a key factor to make sure the quality of linkage components. In this study, some processes, including annealing, quenching, tempering, bending and electroless plating, were applied to manufacture the linkage components. The rod component was rolled by 4Cr13 strip. The bending direction of the component was perpendicular to the rolling direction, in order to prevent the formation of crack during bending process. At the same time, the deburring, coarse grinding, fine grinding and polishing processes had a significant effect on the mechanical properties of the component
