Flat springs

Mollificio Felsineo produces flat springs for the most different applications with the following technological limits:
Materials: stainless steel, high or low carbon steel, special textured, sorbitic steels, copper alloys, brass, bronze.
Thickness from 0,10mm to 5 mm.
The extreme limitation is dictated by the level of 60 Tons of our press.

Spiral Springs

We produce a large range of spiral springs, including violin F-holes springs in stainless steel, high or low carbon steel, special textured, sorbitic steels, with thickness from 0,15 to 2 mm and width up to 80 mm.
The total length of the bands can be in excess of 18 m.
We offer, for those type of springs, special experience in the evaluation of fatigue resistance.
Please contact our technical department for any enquiry in this area.

Shaped springs

For a large variety of applications, we produce complex custom shaped springs on automated machines capable of max 12 controlled axes, using wire in stainless steel, high or low carbon steel, special textured, sorbitic steels, copper alloys, brass, bronze.
Wire diameters between 0,2 and 4 mm.

Compression springs

We produce with competence all types of currently used compression springs in shapes like : cylindrical, conical, barrel, hourglass, constant or variable pitch, using stainless steel, high or low carbon steel, special textured, sorbitic steels, copper alloys, brass, bronze
