Tessari was founded in 1950. The brothers Erminio and Orfeo Tessari create a structure, in a small room used as a workshop, which deals mainly with repairs in the heavy engine sector, being among the first workshops in Italy with specific expertise on injection equipment in particular and in the mechanical field in general. After a few years (1955), they moved to a later site of a certain size and with adequate space, and their activity, while maintaining their primary commitment, expanded into the marine sector, with peripheral offices in Chioggia and Caorle, and into the industrial sector with the acquisition of representatives of leading international companies.
