LEONI Portugal
LEONI AG's industrial unit in Guimarães was founded in 1991, initially focusing on the manufacture of electrical wiring for light passenger vehicles. However, in 2001, the unit underwent a strategic reorganisation, shifting its focus exclusively to the development and production of wiring systems for commercial vehicles and industrial machinery.
This plant is characterised by a high degree of operational complexity, reflecting both the diversity of its portfolio and the flexibility of its processes.
