LACROIX has embarked on an ambitious project to build a plant at the cutting edge of technology that respects the environment and is designed to provide superior quality of work life for all employees.

The SYMBIOSE project, led by the Electronics activity of LACROIX, relies on the power of an ecosystem of recognized industrial experts who support the project. The plant also draws its strength from its location in the Pays de la Loire as it is based in Beaupréau, just a few kilometers from the current plant. The aim is to build a new French flagship of electronics, a symbol of industrial renewal in France with a European and even a global reach.

The Electronics activity of LACROIX has begun the process of transforming its production model to align with its Smart Industry strategy. This increase our competitiveness in the traditional markets for industrial electronic systems and meet the specific challenges of promising new markets such as mobility and industrial IoT.
