Within a typical plant, stamping presses are turning out several automotive components daily, from body panels and chassis to brake and lighting parts. Those presses likely include both hydraulic and servo presses, depending on the requirements of the job.

And because of the range of metal that can be successfully formed by traditional stamping presses, allowing manufacturers to create high-quality metal parts at affordable prices, those machines will likely live on the plant floor for a long time to come.

The car camshaft uses lobes (called cams) that push against the valves to open them as the camshaft rotates; springs on the valves return them to their closed position. This is a critical job, and can have a great impact on an engine's performance at different speeds.

The key parts of any camshaft are the lobes. As the camshaft spins, the lobes open and close the intake and exhaust valves in time with the motion of the piston. It turns out that there is a direct relationship between the shape of the cam lobes and the way the engine performs in different speed ranges.
