Forged Discs & Gear Blanks Open Die Forgings Forged Parts - Rods Rings Discs Bushings

Open die forging is an important technique for many types of manufacturing. It allows rough and finishing shaping of metal, most commonly steel and steel alloys. It requires a die that is open on the sides, allowing the workpiece to move freely, in a lateral direction, when struck. This type of design also allows for forging of very large workpieces, in some cases, weighing many tons and having great length and width.

Open die forgings can be worked into shapes which include discs, hubs, blocks, shafts (including step shafts or with flanges), sleeves, cylinders, flats, hexes, rounds, plate, and some custom shapes.

In Open die forging, a rough or precision machining is normally further required after the open die forging process as imprecise dimensions are achieved by hammering. Thus, open die forging is more suitable for large parts in a number of tons. Generally, the products in forging method include forged long shafts, forged rollers, and forged cylinders, which are mostly used for the application of railway and aircraft industry.
