The manufacturing sector in Mayenne is characterized by a mix of established large groups and mid-sized firms, with a notable presence in food and beverage, automotive, and electronics manufacturing. Companies like Lactalis Group, with over 21,000 employees, produce a wide range of dairy products. Walor specializes in forged and machined mechanical parts for the automotive industry, while Selha Group provides electronics solutions. DIRICKX is a global leader in perimeter protection.
A significant pattern observed is the concentration of headquarters in Laval, which hosts several of the largest manufacturers. This includes Lactalis Group, MoldTecs, a global supplier of plastic parts for the automotive industry, and COFIDUR EMS, an electronics manufacturing company. This suggests Laval serves as a central hub for industrial activity within the department.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
