Together with our customers,we design die and hand forged partswith properties perfectly matching theirintended application. This work also includesnew titanium alloys.Since more than four decades, OTTO FUCHSdeveloped a special process technology fortitanium. This includes: CNC-controlled hydraulic, hand- anddie forging presses allowing reproducibleprocesses a centrally monitored heat-up and heattreatment unit special hot die-forging and“near-net-shape” forging technologyWe manufacture several hundred differenttitanium Dieforgings with individual weightsranging from 20 grams to several hundredkilograms. Our largest die-forging press witha pressing force of 300 MN enables us toforge parts with a max. plan view up to10.000 cm 2 .2100 x 320 x 130 mm“Titanium near-net-shape” Flap Track 2-6,Ti6Al4V, 110 kg2320 x 400 x 120 mmFlap Track 1,Ti6Al4V, 288 kg
