New drop-hammer in Custines: a strategic investment in 2019 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. A preparation press of 2,500 t with large dimensions and allowing hot extrusion of preforms. Several kinds of furnaces to heat steels, aluminum, copper and nickel alloys and titanium at aerospace quality levels. These large furnaces will improve our production capacity and our competitiveness. Tooling design and manufacturing onsite, and internal capacities of machining. Thermal treatments and finishing on the Custines site for all forged metals. Non Destructive Testing: ultrasonic testing ; penetrant testing ; 3D dimensional control ; magnetoscopy ; electrical conductivity testing 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. Ring rolling mill 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.
