The alliance

CALIP Group is the shareholding alliance of two industrialists specializing in precision mechanics: Calip Normandie and MGF Grimaldi.

Created in 2014 to meet the requirements of major clients in all industrial sectors: aeronautics, automotive, defense, medical and robotics, CALIP Group pools the know-how of 400 employees and the production force of 5 factories spread across 2 countries : France and Romania.

In 2024, CALIP Group acquired SPEMA, specialized in high precision mechanics.

It is the consideration of complete manufacturing management, by integrating Lean management into our processes, innovative processes and supply chain management for surface treatments and painting, which is making the company evolve. from a simple machining subcontractor to a mass production assembly line for complex parts.
