The Company was founded in 1965. Company founder was h.q. master Milorad Crnobrnja, master works by one of the best masters who grow from the GSP School, then the most popular middle school. It was a generation 1947/1948 year. His knowledge in Metalostrugarska skills was almost absolute. On turner, as the most universal machine, he could do what now masters of the so-called vocational education need several machines. We, who had the honor and happiness, to learn from him the secrets of this craft, as well as dozens of his students, later top chefs; we hold a kind of wall to the global economy, the single production. Highly serial production of all, led to disorders in relationship man and quality which inevitably led to a crisis in a broader sense, the consequences of which have yet to feel it all. In addition to top chefs, engineers and other professional associates, the company has significantly large fleet of vehicles, which may at any time to respond to any technological application in these areas.
