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 MT, 40,000 MT and 65,000 MT hydraulic presses.
Closed die forgings
Hammers
- 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
- Die forging presses up to 65,000 MT
- 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.
The largest closed-die forging press in the Western World
- A powerful press
- 65,000 MT power capacity
- Weighing twice the Eiffel Tower
- Extreme precision
- Speed control and centring
Closed-die forging for disks
- The 40,000 MT closed-die forging press is the centrepiece of our fully-automated EDPL (Engine Disk Production Line).
- Lean workshop integrating all steps from the preparation of our own billets to final ultrasonic tests.
