Ohio Crankshaft Co. of Cleveland, Ohio, produces large crankshafts, camshafts and other customized critical components for diesel engines, pumps and other reciprocating equipment. In 1934, the company developed a proprietary process using high-frequency electrical current that could selectively heat, harden or melt metals. Named the TOCCO process, it was a technology with which steel parts could be heated and hardened within seconds and produce parts with wear resistance superior to other technologies at the time. The Packard automobile was the first car to use an induction-hardened crankshaft, and other automobile manufacturers would soon follow suit.
