About the SCHMID GROUP
The SCHMID GROUP, headquartered at Emil Schmid Maschinenbau GmbH & Co. KG in Sonnenbühl (Baden-Württemberg), develops and manufactures special machinery and complete production systems for industry, in particular for the automotive sector. Core competencies are assembly technology, handling and linking technology, and special machinery engineering for conventional and electric powertrains: stator production with hairpin technology using rectangular copper wire, rotor assembly, e-motor final assembly, battery final assembly and fuel cell stack assembly, as well as engine, transmission and axle assembly lines. The group combines the expertise of Emil Schmid Maschinenbau (special machinery), EST Technologie (fastening, joining and control technology), Schmid Cleantech (aqueous low- and high-pressure cleaning as well as deburring), Schmid E-Motive (stator prototypes and small series) and Schmid Machinery (service Asia). Services include feasibility studies, engineering, in-house manufacturing, commissioning, training and turnkey project management. Locations are in Sonnenbühl, Aalen-Ebnat, Engstingen (DE), Nuvolera (IT) and Nanjing (CN).
