About us


Our production company perfectly integrates into Italian mechanical industry by supplying a large product catalogue of castings of machined iron cast: we range from clamping plates to squares and boxes, from reference planes to control bars and many other items listed in our catalogue.

Clamping plates still remains our flagship product thanks to several utilization, weight range and T-slots customization.

We use the so called “American planing”, a finishing process which gives an added value to our products since surfaces have fewer points of contact compared to milling and decreases annoying suction effect.

The planing tool ripples iron cast superficial slats, increases hardness and decreases sliding wear.

Our machinery allows to provide third parties with milling, drilling, boring and grinding and we also have a dedicated department for precision engraving using pantographs both on rings and plates.



In 1946 Giuseppe Bonanomi, had been working for 30 years for famous FRANCO TOSI company in Legnano, as head of the tooling department, when he decided, thanks to his expertise, to extablish his own company to give vigor to a sector in turmoil , like the post-war metalworking one.
