The GHM foundry in Sommevoire specializes in the manufacturing of cast iron parts, weighing a few grams to a ton, in sand casting. The flexibility of the manufacturing process allows producing prototypes, small and medium series, or even remaking parts identically. Founded in 1857 by Antoine Durenne, who bought a metallurgical plant created twenty years before, the GHM factory has evolved by constantly innovating throughout the decades. It is today recognized worldwide for the quality of its cast iron and the finesse of its works of art.
