Created in 1971, the French production site is a precursor in the industry of the future. A site that has developed a long-term expertise and a customised offer to support our clients with their most complex projects. 

In 2016 our factory was labelled “Industry of the Future Showcase” for its digitalisation project and the factory automation. A distinction that underlines the ability of our company to anticipate the future, while installing development on a sustainable basis. 

In 2018, 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 ensure the fulfillment of its employees: Symbiose. A few years later, the site was created at Beaupréau-en-Mauges, symbolising the industrial revival in France.
