Comer S.P.A.

Comer S.P.A. was established in 1978 by the entrepreneur Stefano Compagnoni, after gaining in-depth experience in the manufacturing of molds. Over the years Comer has experienced strong growth and has several different production sites, including the two latest locations near Genoa in Italy: San Colombano Certenoli, owned by Comer since 1990 and specialized in valve manufacture, and Casarza Ligure, estabilished in 2004 and specialized in fittings production, especially large diameters. Despite our success, Comer remains a family-owned company, which is still managed by the founder Stefano. Compagnoni joined by his brother Giorgio and his daughter Roberta

The molds used for the production of fittings and valves are made on site in a specialized department. Since the foundation of Comer, it has developed and increased both our technical know-how to design moulds and its skills for mould-technology production.
