The Companies of North Coast represent a transformation from an old-school tooling company to a high-flyer in Ohio's advanced materials industry. Brooklyn Heights-based North Coast Tool & Mold was founded in 1976 and North Coast Composites was launched in 2003. North Coast took a giant step forward seven years ago when it moved into production of composite parts. North Coast Composites, which manufactures carbon, Kevlar and fiberglass parts, primarily for the aerospace industry, shares 65,000-square-foot building with its sister company -- and the two work hand in hand. In 2009 employment increased between 24 and 27 percent, to 33 employees. 2009 sales were up 75 percent from the year before and expected to double in 2010.
