Accumold, a global leader in the design, development and production of micro-engineered parts for various high-tech industries, cut the ribbon Tuesday on its second expansion since 2011 in Ankeny. Gov. Terry Branstad and other government and economic development officials were present to dedicate the 40,000-square-foot, $10 million expansion that will result in more than 200 employees in the next three years. The addition is capable of withstanding an F-5 tornado. Accumold CEO Roger Hargens said the expansion, which has the capability to be a stand-alone facility because of its unique features, represents a “vastly different change in our operations and our approach to business.”
