This long history proves the skill and efficiency of our employees. Today, we operate in two production sites in Trenčín (after moving our operations in Ilava to the Trenčín Industrial Park in 2022).

In early 2024, we successfully opened Shared Service Centers in Dubnica nad Váhom, located in the city's tallest building – ORION.

At LEONI, we focus on the future. Our EMO – electromobility production now specializes in wiring harnesses for electric and hybrid vehicles, serving top global brands. At the same time, we continue our long-term partnership with VW Group costumer, which confirms high-quality of our work.
