The final user often faces several special requirements concerning the pieces to be stocked. The main ones are the elastic resistance to breaking, fatigue and corrosion, seal under pressure, resilience.
Forging allows the achievement of an excellent compromise among all these requirements, and this compromise will improve by choosing the specific alloy, the heat treatment, etc...
The mechanical resistance of forged pieces is very high because of the internal "fibre structure" brought forth by the metal forging.
The stretching peculiarities and the limit of elasticity are considerable if compared to other techniques.
After forging, pieces may be subjected to several treatments: ageing, hardening under different temperature and speed, mechanical treatments.
Even for small series the choice of forging is often the most economic solution to produce complicated pieces, because it allows to minimize the amount of raw material in progress, as well as the amount of metal to be removed through machining.
Forging sometimes allows to achieve in a single part what other techniques get through assembling. The forged part peculiarities may be summed up as follows:
-homogeneous structure with no porosity
-maximum strength values for every chosen material (tensile strength, fatigue limit to alternating flexure, stretching and resilience)
-complete liquid and gas seal
-particularly clean and smooth surfaces
-high dimensional precision, therefore strict tolerance fields
-high chemical resistance
-good electrical conductivity
Our forgings are manufactured on presses with a power ranging between 200 and 6300 tons, with the possibility to obtain pieces having a unit weight from few grams up to a maximum of about 40 kilos.
