Cold forging

Production with cold forging technology, by means of horizontal multi-station presses.

The work organization in the departments allows us to be flexible and fast in machine set, a basic requirement by making small-sized batch production and with a very high number of different items.


Ø 6 mm – 33 mm
L 10 mm – 240 mm


Carbon steel
Stainless steel
Copper alloys
Aluminium alloys



The threading department is made up of several machines, both roller and comb. The introduction of new generation machines has made the department even more efficient.





Machining operations

At the beginning of 2017 we created a new internal machining department for our cold forging products. Our goal is to control this phase and to be able to push further with high precision machining, highly qualified staff and latest generation machineries.
