ForceBeyond provides world-class open die forging (also known as free forging or smith forging) for massive, high-stress industrial applications. As part of our comprehensive custom forging services hub, we shape heated metal between flat or contoured dies that do not completely enclose the material, producing extremely heavy components with unparalleled structural integrity.
Because open die forging does not require part-specific tooling, it is the most cost-effective method for low-volume runs, rapid prototyping, and parts too large for closed die forging presses. We supply heavy forged blocks, step shafts, discs, and rings using a broad range of alloys, including high-performance exotic superalloys like Inconel 718 forging and specialized ECO BRASS C69300 forging.
Our open die forging capability relies on the skill of press operators to incrementally shape the metal, which is subsequently precision-machined to final print tolerances. ForceBeyond manages massive weight capacities to manufacture diverse geometries:
| Forged Geometry | Typical Applications & Related Technologies |
|---|---|
| Step Shafts & Spindles | Power generation rotors, marine propeller shafts, and heavy industrial drive shafts. |
| Discs & Hubs | Gear blanks, heavy-duty machinery hubs, and high-pressure pipe flanges. For high-volume precision alternatives, compare with our closed die forging process. |
| Blocks & Rectangles | Tool steel blanks, massive structural supports, and heavy equipment bases engineered from structural alloys or nickel-based superalloys. |
| Cylinders & Sleeves | High-pressure containment vessels, hydraulic cylinders, and extrusion press components. |
| Rings (Mandrel Forged) | Pressure vessel connections and heavy bearing races (for seamless high-production ring options, see our dedicated Rolled Ring Forging capabilities). |
When components operate under critical stress, internal structural defects can result in catastrophic failure. Compared to traditional casting processes like sand casting, investment casting, or die casting, open die forging delivers superior metallurgical density and strength.
Because open die forgings yield near-shape preforms, ForceBeyond seamlessly transitions your components from the forge shop to complete post-processing finishing across our global forging network.
ForceBeyond delivers high-integrity open die forgings engineered for demanding operating environments:
No. Open die forging produces a rough, oversized shape. Because the metal is not constrained by a custom mold, there is a material allowance left on the surface. The forging must undergo heavy CNC machining to reach its final print dimensions.
Almost any forgeable metal can be open die forged, including carbon steel, alloy steel, stainless steel, titanium alloys, and nickel-based superalloys (like Inconel).
While sand casting can produce large parts closer to net shape, castings inherently carry a risk of internal porosity, shrinkage, and a brittle grain structure. Open die forging mechanically works the metal to guarantee a dense, highly refined, defect-free internal structure, which is mandatory for parts subjected to high stress, heavy loads, or extreme pressures.
