About the Schlote Group
The Schlote Group is a family-owned company founded in 1969, headquartered in Harsum near Hanover, with around 1,500 employees at nine locations in Germany, the Czech Republic and China. Its core competence is industrial metal processing in medium and large series, in particular the machining of casting components made of aluminium, iron, steel and forged materials in CNC machining centres and automated production lines. The Group manufactures complex engine, transmission and chassis components as ready-to-install assemblies, complemented by cleaning, deburring, leak testing, vacuum pressure and impregnation as well as assembly. Through Schlote Technology GmbH, the company also offers prototype and small-series production according to drawing, fixture design, die casting mould manufacturing (aluminium, magnesium, zinc) as well as automation and special-purpose machinery with assembly, welding and leak testing systems. As a development partner and series supplier, Schlote serves not only the automotive industry but also commercial vehicle, agricultural machinery, rail and special vehicle construction as well as general mechanical engineering.
