Open-Die Forging
Open-die forging is a metal forming process that shapes heated material between dies that do not fully enclose the workpiece. It is commonly used for large shafts, blocks, discs, rings, and heavy industrial components requiring controlled deformation, mechanical strength, and suitable internal material integrity.

Manufacturing overview
Open-die forging uses repeated compressive deformation to transform metal into relatively simple or intermediate geometries.
Common operations include upsetting, drawing out, cogging, flattening, and piercing.
Unlike closed-die forging, the material is not completely confined within a shaped die cavity, making the process particularly useful for large components and relatively low production volumes.
Typical applications include turbine shafts, large industrial discs, pressure equipment components, heavy machinery shafts, and forged blocks.
Suitable materials include carbon steel, alloy steel, stainless steel, and selected nickel-based alloys.
Forging process design considers starting stock dimensions, deformation ratio, grain flow, temperature distribution, and required mechanical properties.
Large forged components often require controlled heat treatment, rough machining, and final CNC machining.
Buyers should specify material grade, forging dimensions, finished component geometry, mechanical properties, quantity, and required certification.
Quality requirements may include ultrasonic examination, tensile testing, hardness verification, chemical analysis, and material traceability.
