Stackpole Powder Metal Group, the Powder Metallurgy parts division of Stackpole International, Ancaster, Ontario, Canada, has announced the acquisition of E. Zimmermann GmbH (Zimmermann), located in Oehringen, Baden-Wuerttemberg, Germany.

Zimmermann specialises in manufacturing processes for the machining of differential housings and crankshaft bearing cups in the automotive industry. In 2020, the company’s sales were reported to be €16.4 million with a total of 130 employees.

Zimmerman was founded in 1970 by Eberhard Zimmermann and has been managed since 1997 by his children, Rolf and Ute Zimmermann. The company’s manufacturing expertise and geographic footprint, as well as long-standing customer relationships in Germany, are expected to have synergy with Stackpole’s Powder Metallurgy technology, multinational operations and customer base.

The combination of Zimmermann’s knowledge of machining of differential housings and Stackpole’s global resources provides the Powder Metal Business Unit with a unique opportunity, states Stackpole. The acquisition is expected to accelerate the company’s machining know-how into the evolving sector of new energy vehicles with innovative powertrain requirements, including new power transmission systems.
