Open Die Forging.
Strength for Large Sections. Open die forging is built for large, strong, custom metal components where grain flow, internal soundness, and mechanical strength matter more than tight near-net detail. Amsol supports shafts, rings, blocks, discs, bars, heavy-duty blanks, and custom forged components for OEMs across heavy engineering sectors.
From Billet to Forged Component — 6 Steps
Every open die forged component at Amsol follows a controlled route from drawing review to forging, heat treatment, machining, inspection, and documentation.
Open Die Forging Capability
Open die forging supports large-section strength, internal integrity, customised dimensions, heat treatment, machining, and inspection for heavy-duty OEM components.
Forging Materials for Large, Strong Components
Amsol supports material selection based on component size, load requirement, corrosion resistance, machinability, heat treatment route, and end-use duty.
| Material | Use | Strength |
|---|---|---|
| Carbon Steel | General heavy-duty forged parts | Cost-effective, machinable, suitable for large components |
| EN8 / C45 | Shafts, blocks, machine parts | Good strength and machinability |
| EN24 / 4140 | High-load shafts, rings, pressure-duty parts | High tensile strength, toughness, Q&T performance |
| Stainless Steel | Corrosion-resistant forged parts | Suitable for marine, oil & gas, and process equipment |
Choose Open Die Forging When Size and Strength Lead the Decision
Open die forging is strongest when the component is large, strength-critical, custom-sized, and planned for heat treatment or machining after forging.
| Choose Open Die Forging When | Why It Helps | Amsol Route |
|---|---|---|
| Part is large and strength-critical. | Forged grain flow improves mechanical performance. | Forging route selected around load, geometry, and grade. |
| Quantity does not justify closed die tooling. | Open die process supports custom sizes without expensive dedicated tooling. | Low-tooling route for blocks, discs, shafts, rings, and blanks. |
| Internal soundness is important. | Forging refines the metal structure and supports UT where required. | Inspection support with hardness, dimensions, UT, and MTC documentation. |
| Component will be machined after forging. | Forging provides strong stock for final accuracy through machining. | Rough machining, final CNC, drilling, turning, grinding, and inspection. |
| Custom size, custom grade, or custom geometry is needed. | Open die forging handles heavy, non-standard component requirements. | Drawing review, grade review, heat treatment planning, and cost direction. |

Where Amsol Open Die Forgings Go
Open die forged components are used where large sections, load-bearing duty, internal soundness, and post-forging machining decide the part’s performance.
Forging Strength Verified Through Certificates, Testing, Machining, and Inspection.
Open die forging quality depends on material traceability, heat treatment discipline, hardness verification, internal soundness support, machining control, and final dimensional inspection.
