Waupaca Foundry announced it will merge with Hitachi Metals Automotive Components USA.

The merger is part of a larger reorganization within Hitachi Metals Foundry America designed to position the integrated organization for growth and meet customer demand.

Waupaca Foundry will assume the assets and liabilities of HMAC.

Both companies are currently subsidiaries of Hitachi Metals Foundry America (HMFA). After the merger, HMAC will become a division of Waupaca Foundry, but will continue to operate under the HMAC name.

The merger is expected to be complete on April 1.

Waupaca Foundry produces gray iron, ductile iron, and austempered ductile iron castings. The company is North America’s leading supplier of casting components to the automotive, commercial vehicle, agriculture, construction and industrial markets.

The iron castings supplier employs more than 3,900 people at six manufacturing facilities, including three in Waupaca, and one each in Marinette, Wisconsin, Tell City, Indiana, and Etowah, Tennessee.

HMAC produces cast, machined and assembled ductile iron suspension and exhaust components for global automotive OEMs.

It currently operates machine and assembly plants in Effingham, Illinois, and Wellsboro, Pennsylvania, as well as a ductile iron foundry in Lawrenceville, Pennsylvania. The company employs 485 people across all locations.

“This reorganization further unites Hitachi Metals’ product design engineering expertise and materials development with Waupaca Foundry’s manufacturing excellence,” said HMFA President and CEO, Eddie Nakano. “The merger will unite an experienced leadership team that is focused on delivering the most innovative products and technology to a growing base of global customers.”

“The merger with HMAC allows us to further integrate castings and value added services for our customers in diverse markets,” said Gary Gigante, CEO of Waupaca Foundry. “We are committed to being the world’s leading casting solutions provider and this is a critical step in achieving that goal.”

According to HMAC CEO Mike Nikolai, the merger is a response to increased customer demand.

“Centralizing machine and assembly operations allows us to be more flexible in meeting the evolving demands of our customers,” Nikolai said. “We’ve already increased overall operational capacity and are positioning our organizations for long-term, sustainable growth.”
