OUR HISTORY

Origins

Born in 1939, Mr Rossi begins his career in the early ‘60s, after terminating his studies at the famous Aldini Valeriani Technical Institute in Bologna, whose scholars created many world-leading enterprises in the region.

The journey began in a company manufacturing die casting and plastic injection moulds, where Mr Rossi was able to follow his passion for the mechanical world, soon becoming chief production supervisor.

First Stone

In 1968 Mr Rossi decides to set up his own business, creating COMEST, which stands for Costruzione Meccanica Stampi (Mechanical Die Casting Dies Manufacturing).

Together with a few expert collaborators, he works night and day to lay the basis of the new-born company.

Mr Rossi and his team, working with strong commitment and determination, will be able to build and equip a new workshop of around 4000 m2, hiring more and more workers.

New orders will rise and the number of machines grow.
