Experience and expertise

A small Italian firm, but one "that can face the great ones", as described by Lino Grosso, mechanical engineer and CEO of the Company, in an interview appare on the Italian newspaper “La Repubblica” in 2010. Even today, nearly sixty years after its founding, the company is still a milestone point in Italy for precision machining, interested not only in succeeding in this field, but also in keeping Made in Italy alive. Over the years, significant projects in the field of aerospace research and telescopes have been mostly carried out by young and very driven employees. Two generations of engineers and skilled workers grew professionally in the structure of Cercola (near Naples) and almost all of them have started their own careers right after their work in Marotta Ltd.
