Lebronze alloys is increasing its closed-die forging & heayy stamping capabilities by investing in a new 40,000 kgm forging hammer.
This production line will forge large parts weighing up to approx. 900kg, in special steels, stainless steels, in aluminum, copper-based and nickel-based alloys, as well as titanium.
Within the Custines industrial site, the new hammer will benefit from a fully integrated process. It will be combined with a large set of high-performance facilities, to offer unique capacities in Europe:
The new 40,000 kgm (400 kJ) double acting drop-hammer will complement to the existing forging capabilities in Custines: another hammer of 16,000 kgm, open-die forging, screw press of 2,500 t, Maxi-Press of 2,500 t. The Custines factory is ISO 9001 and EN 9100 certified.
Building on its renowned closed-die and open-die forging expertise, LBA will therefore be able to offer more complex forgings, dovetailing customer needs.
Examples of products addressing the demand of international growing markets:

Our group has a wide range of forging capabilities including 50 machines:
More than 30 hot-stamping and closed-die forging presses from 100 to 4000 tons and 9 drop-hammers from 3 to 40 000 kg.m organized in 8 hot-stamping lines and 15 closed-die forging lines,
3 open-die forging presses from 1250 to 2750 tons,
1 ring rolling mill with 120 tons axial power and 90 tons radial power, for a maximum diameter of 2500 mm and a maximum heigth of 500 mm,
2 cold-forming Hatebur type presses.
Thes forging capability is supplemented by a significant pool of 154 turning and milling machines that gives us the possibility to deliver raw pre-machined or machined parts:
76 machining centers from 3 to 5 axes, including 14 transfer machines,
78 horizontal and vertical machining centers
Open-die forging is a process mastered by the Group and frequently used for production of single or small series parts; that do not require dedicated tooling to be manufactured, or large parts up to 8 tons.
Ring rolling mill is a process recently acquired by the Group through the restart of Forge de Custines, it allows us to produce cylindrical or profiled rings with a circumferential grain flow and allows for machining allowances that are closer than in a traditional forging process . The manufacture of profiled rings requires the production of a tool and therefore is suitable for larger production volumes/ series.
Closed die-forging (for non-ferrous alloys) and hot-stamping (for ferrous alloys) allows to produce parts having more complex shapes compared to open-die forging , but as production of a tool is needed it is dedicated to larger volumes/series.
Cold forming is adapted for small dimensions parts produced from a cut to length bar (slug) or from a long blank, allied with very high production rates. Metal cold working provides excellent mechanical properties and saves heat treatment steps.
Forging is an outstanding solution to answer fatigue component problems when these are subjected to strong and repeated stress over time. The Group has helped numerous customers to improve welded assemblies systems and to evolve towards a more robust forged solution.
Our processing capabilities allow us to manufacture parts according to:
A gross weight from 10 grams up to 800 kg for stamped parts,
A gross weight from 1 kg up to 8 tons for open-die forged parts with a particularly high wrought ratio,
An outside diameter up to 2500 mm for rings,
A wide range of alloys open and die-forged: copper alloys, aluminiums, special steels, titanium and nickel base alloys.
Our products are used by major equiment makers and contractors, especially in the aerospace industry (forged tubes, aluminium rolled rings, steel, inconel or titnium).
In order to offer the best solution, our Engineering Department supports you from the conception to the industrialization of your products, enabling you to benefit from our know-how and redesign to cost experience. The mastering of CAD advanced tools and digital simulation software such as Forge® allows us not only to help you in finding solutions but also in the detailed conception of your new products.
All heat treatments required by our customers on parts we are manufacturing are carried out in-house, this for all alloys produced in the Group.
We are able to perform a wide variety of mechanical tests and metallurgical analysis (micrography, macrography, corrosion) but also non-destructive testing (ultrasonic testing, penetrant testing, electrical conductivity control).
Our Quality Department ensures your most demanding specifications are satisfied. We are not only certified ISO 9001 and 14001, by assurance companies (TÜV, Lloyd’s Register, DNV, ABS or even NADCAP for UT) but by prestigious customers themselves.
Lebronze alloys group masters a wide range of metal processing technologies: continue and semicontinuous casting, sand casting, die precision chill casting (manual, mechanized and automated), centrifugal casting, extrusion, ring rolling, open-die forging, closed-die forging, hot stamping, cold forming, machining, non-destructive testing, etc. We are in a position to support you from the conception to the industrialization of your products, making you benefit from our redesign to cost know-how. We are committed to bring you our experience in order to help you to find the best answer to your needs.
