Our cold forging machines are able to produce, starting from the wire, nuts and coupling nuts with a threads from M4 to M36. In our cold forging process we use non-alloy steels, suitable for plastic deformation and extrusion, while the alloyed steels are employed in heat treatment. We have a wire processing capacity from diameter 6 mm to 44 mm, using C10C, 20MnB4, 23MnB4, 35B2 and many others steels, in accordance with the specific International Standards UNI EN 10263, UNI EN 10269 and UNI EN 10278. Our range of products also includes items obtained through a hot forging process, employing carbon steels such as C40, C43 and C45.
Thanks to our suppliers’ support we are able to manufacture parts up to 75 hexagon with different threads.
We can satisfy any particular need of secondary machining techniques through dedicated systems.
The long relationship with our suppliers of heat treatment allows us to ensure high quality and flexibility in the performance. On our products we can perform heat treatments such as carbonitriding, hardening, normalizing. Each treatment is then performed through optimized process parameters, which depend on the specific material to be treated and on the mechanical and technological characteristics, which must be achieved.
Thanks to a long-standing cooperation with our suppliers we can offer a wide range of inorganic and organic surface coatings to meet the requirements of our customers: zn / znni / znfe / cu / zn flakes. On these treatments we can add sealants / lubricants, to meet the specific requests of a raising resistance against corrosion and to control the friction coefficient. We are able to meet the functional and aesthetic requirements imposed by the major automotive companies thanks to the technical support of approved formulators and applicators.
In the sorting department we use the latest generation of high performance and constantly updated machines; we can ensure the highest quality, by doing automatic selection of different kind of characteristics such as thread presence, dimensional and / or functional dimensions, absence of foreign bodies.
