Pouring the molten metal into the moulds requires years of experience to make the operation successful. The GHM foundry in Sommevoire (Haute-Marne) specialises in the manufacture of castings. The flexibility of sand casting makes it possible to produce prototypes, small and medium-sized series or even identical parts. Founded in 1857, the company has evolved over time through constant innovation. It is now world renowned for the quality of its work and the finesse of its artworks. More than 20,000 tons of cast iron are produced each year in the factory.
