Forging is one of the oldest metal working methods; the metal is heated and given the right shape using a closed die. Closed-die forged pieces can have complex shapes with weights ranging from just a few grams up to 200 kg. For applications that require high-quality mechanical properties, tight tolerances and large series. Materials used are a.o. steel, stainless steel, nickel alloys, titanium, aluminium, non-ferrous metals and super alloys.
