Ing. Erich Geiss GmbH & Co. KG

Elektrotechnische Fabrik

Founded in 1945 at the present location as a trading company for components of armature wrapping used for electric motor repairs.

New offices were established at the same address in 1955. About the same time, the production of motor terminal boards was begun in the extension hall. Incorporation of tool making and pressing were to follow.

Since our founding, we have constructed and manufactured 250 types of forming tools. With these we manufacture ca. 40.000 motor terminal boards daily.

Since the beginning of slip-ring element production, we have used more than 700 different elements and produce these as well from drawings of former, leading slip-ring motor manufacturers.
