LACROIX Group has embarked on an ambitious project to build a plant at the cutting edge of technology that respects the environment and is designed to ensure the fulfillment of its employees.

The SYMBIOSE project, led by the LACROIX Electronics section of the Group, relies in particular on the power of an ecosystem of recognised industrial experts who support the project. The future plant also draws its strength from its location in the Pays de la Loire as it will be 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 or even a global reach.

LACROIX Electronics has begun the process of transforming its production model to align with its Smart Industry strategy. We will therefore be able to 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.

The plant grand opening will occur by the end of 2021.

The 3 pillars of the project

Our ambition is to create the factory of the future: human, digitised, smart, automated and environmentally friendly.

The project is based on 3 main pillars:

  • Industrial innovation

    Creation of France’s first future-facing electronics factory
  • Sustainable and responsible innovation

    Smart, ecological construction with high energy performance
  • Social innovation

    People at the heart of the project, in a networked building open to its ecosystem

I am very pleased to see that the teams are involved and committed to carrying out the Symbiose project. Our employees are enthusiastic about the many projects we have launched in anticipation of the move.
This transformation affects the entire company. We are implementing lean management throughout the workshop, but also deploying a lean office in support functions and in the workplace. This allows us to make faster progress in putting the automation and digitisation solutions we are working on into action.
