Open Die Forging: Precision Heavy Metal Components Without Tooling Costs
How CIC Specializes in Open Die Forging Technology
At Custom Industrials Company (CIC), our open die forging process delivers superior structural integrity and controlled grain flow for the most demanding heavy industrial components. By manipulating hot billet material between hammer blows without closed dies, we produce rings, rounds, blocks, step-downs, discs, and custom shapes with excellent mechanical properties, no tooling charges, and rapid delivery — making CIC the preferred partner for low-to-medium volume forged components across aerospace, energy, and industrial markets.

Open Die Forging FAQs
What is open die forging and how does it work?
Open die forging shapes hot metal billet by applying compressive force between flat or simple-shaped dies. The workpiece is repeatedly repositioned between hammer blows to achieve the desired geometry, resulting in excellent grain flow, superior mechanical properties, and high structural integrity.
Why is there no tooling charge for open die forging?
Unlike closed die forging, open die forging uses standard flat or shaped dies that work any geometry without custom tooling. This makes it immediately economical for one-off pieces, prototypes, and small production quantities where closed die tooling costs would be prohibitive.
What is the maximum size part CIC can open die forge?
CIC's open die forging capabilities cover components from 10 lbs up to 25,000 lbs, accommodating rings, rounds, blocks, discs, step-downs, and custom special shapes across a wide range of alloys.
How does open die forging compare to casting for structural parts?
Open die forgings produce superior impact strength, fatigue resistance, and ductility by mechanically aligning the grain structure to the part geometry. Castings can achieve similar shapes but with lower inherent mechanical properties, making forgings preferred for high-stress, safety-critical applications.
Can CIC machine the forging after completion?
Yes. CIC offers in-house machining capabilities to deliver pre-machined pre-forms or fully finished components, eliminating the need for a secondary machining supplier and reducing your total lead time.
