Shot peening can be used to help with breakage problems on many parts. Axles, rods, crank fillets, gears, and springs all benefit from shot peening. Shot peening is cheap-the cost to shot peen a ...

Springs head to the shot-peening machine after grinding. Described as akin to a massage, shot-peening is a process that exposes the surface of the coil to metal shot moving at high velocities in ...

Shot peening has a dark box history relative to metals, not fully understood when it was discovered by accident in the automotive industry in the 1920s. Two similar but different metal springs ...

Fortunately, the capability to shot peen the material has let researchers create various prototypes, including a ceramic leaf spring and a concave mirror. The technique is now advanced enough to ...

A final shot-peening process further increases the springs' strength. As you might expect, the additional steps in the manufacturing process also mean additional cost. The big question is ...
