VALVE PUSH RODS
Value push rod is a highly strained component in the engine and hence it requires "Zero defect" manufacturing. There are two types of valve Push Rods .One is Forged Type and the other is Tubular type. Forged push Rods are manufactured on Electrical upsetting Machines and Hydraulic. Presses. They are subsequently induction hardened on both ends. Tubular Push Rods are manufactured by projection welding of cup end on one side and ball on other side. In some cases, balls are welded on both ends. Both ends are subsequently Induction hardened.
