Locations
Greenville, SC
Our US headquarters for MINILEIT Inc. is based in Greenville, SC. As a 100% subsidiary of ISOLITE GmbH, from here we not only manufacture components but also operate extensive sales activities aimed at opening up new markets in North and Central America. This enables us to supply well-known German OEMs and American companies in the immediate vicinity directly, offering them crucial benefits in terms of logistics, quality and delivery reliability.
Wixom, MI
In 2017, we opened a new production and distribution site in Wixom, Michigan. The Detroit area's history is deeply rooted in the motor industry. The MINILEIT team, with its “Sales” and “Engineering Support” divisions, is thus the first point of call for customers in North America. In view of the high level of local demand, production in Wixom is focused primarily on hot-end products.
