O M C has its seat in Certaldo, in Tuscany, a town famous for its historical medioeval centre and the flourishing activity of numerous industrial concerns. The activity of O M C  began in 1968 and since 1979 the company has been the exclusive property of the Calvetti family.
The firm after passing from mechanical manufacture on behalf of a third party in the early years with supplies of processed parts to customers like the STATE RAILWAY, has begun the construction of industrial machines for the most varied lines of business.
In the early eighties, a generational change took place even if a strong link with the old management remained, this has brought an increase in the creative and structural capacity of the firm.
Today O M C  has the means to design and build its machines entirely on its own premises. The machines are designed by a highly technical office supplied with the most modern equipment. The production range includes all the machines requested on the specifications of the customers, not present on the market, for the most varied lines of business.
