CLEVELAND -- It's only one of seven in the United States -- a press capable of applying 50,000 tons of pressure.

The Alcoa company's massive machine creates parts with precision unmatched by other presses for both military and commercial aircraft.

"As the molten metal gets squeezed into shape, it's actually filling the cavity that makes the shape of the part," says Mike Kinney, location manager.

Heat and pressure, just part of a closely guarded equation.

"The control system is really what separates it from all the other presses in the world," Kinny continues.

The press itself is massive. There are five stories above ground another seven stories below ground -- mostly hydraulics.

But this press, which supplies more than 100 local manufacturing jobs, almost disappeared.

In 2008, a crack was discovered in the company's original press.

Alcoa invested $100 million and spent two years completely rebuilding the 12-story structure, anticipating large military contracts.

Instead, cutbacks in defense spending have resulted in fewer military planes being built.

Alcoa is now going after more contracts to build parts for commercial planes, working closely with engineers to design lighter, stronger and larger parts that were not possible to build in the past.
