Forgiatura blocco uso largo di morire

In making a forging, the metal is worked twice under tremendous pressures. First during rod extrusion, drawing or rolling and then during forging. The double working under pressure, compacts the metal, and produces a very dense and refined grain or fiber structure. The tensile strength of the parts is thereby increased, and resistance to impact and abrasion is enhanced.

The dense non-porous forged metal permits the designer to specify thinner sections without the risk of leaks. Often, the thinner forged parts result in lighter weight and lower piece cost compared to other manufacturing processes.

A forging produced in a steel die with close tolerances offers several advantages. Overall part dimensions are held closer than in sand casting. Dimensions show minimum variation from part to part allowing for automatic chucking and handling in subsequent operations. The precise designs on the die surface can produce sharp impressions on the forging surface, which is normally not the case with other forming processes.

Mass production of forged parts lends itself to maximum savings. However, smaller quantities of copper alloy forgings can also prove economical when specific design parameters must be met. These requirements include leak integrity, close tolerances, high strength with low weight, and non-symmetrical shape.
