The list, created by business news website Crain’s Detroit Business, ranks private and public companies headquartered in metro Detroit by dollar revenue growth between 2009 and 2011 and percentage revenue growth during that same period.

Metaldyne ranked number 21 on the list, having had revenue growth of 59% between 2009 and 2011, from US$630 million to over US$1 billion.

Thomas Amato, Metaldyne’s president and CEO, explained how the company has achieved this growth. “We focused our product line to support some of the most fuel-efficient automotive engines and transmissions in the market,” he said. “The trends towards more sophisticated powertrains require a need for high-performance, metal-based and noise-vibration-harshness solutions, which is where Metaldyne comes in."

Metaldyne says that its revenue in 2012 is expected to continue growing, as the company expands globally. The company recently relaunched and repositioned its facility in China and purchased and launched a new facility in the Czech Republic.
