Closed die forgings

Aubert & Duval designs, processes, produces and sells sophisticated metallurgical solutions for the most demanding industries’ projects. Aubert & Duval is active in melting and hot conversion by forging, close-die forging and rolling of special steels (including stainless steel), superalloys, titanium and aluminum alloys. Aubert & Duval also produces alloy powders and hipped parts. The main products are bars, forgings, closed-die forgings and powders. As a specialist in upscale metallurgy Aubert & Duval operates several closed die facilities, such as its 22,000 T, 40,000 T and 65,000 T hydraulic presses.

Hammers

Aubert & Duval can manufacture forgings by hammer or drop forging

 

  • From 3,500 to 60,000 kg/m
  • Forging hot metal between a stationary die and a dropping die. The high velocity of this hot working process gives small and medium forgings an optimised microstructure.

Closed Die Forging

Aubert & Duval’s new 40 Kt closed die-forging press

 

  • Die forging presses up to 65,000 tons
  • Closed-die forging is the process of forming complex-shaped parts from a metal semi-product between two engraved tools (dies) by pressing with a closed-die forging press.
  • Aubert & Duval is a world forgings supplier in aluminum, superalloy, steel and titanium materials made with close-die forging process for critical applications like: aerospace, energy and defense.
