Custom Hollow Forging by Drawing is a precision engineering solution specifically designed for critical cylindrical applications where the component must sustain high loads across its wall section, internal bore, and end faces. By prioritizing wall-thickness consistency and bore straightness, these forgings provide the structural integrity required for the most demanding industrial environments.
Engineered to exceed standard cylinder specifications, our custom hollow forgings are developed based on precise client drawings. This tailored approach ensures optimal material distribution, enhancing both the operational performance of the part and the efficiency of downstream machining processes, making it an ideal choice for non-standard heavy hollow components.

| Metric | Fabricated/Cast Parts | Custom Forgings |
|---|---|---|
| Structural Integrity | Lower (Potential Weld Weakness) | Superior (Continuous Grain Flow) |
| Pressure Resistance | Moderate | Maximum (High Reliability) |
| Machining Waste | High (Irregularity) | Low (Optimized Near-Net Shape) |
| Service Life | Standard | Extended (Better Fatigue Life) |
| Compliance Cost | Higher (More NDT Required) | Optimized (Inherent Quality) |
We provide a wide range of materials including carbon steel, alloy steel, and stainless steel, as well as specific grades based on customer technical drawings.
Bore straightness is managed through precise forging planning and controlled machining allowances, ensuring the final part meets strict dimensional tolerances.
Yes, we can coordinate third-party witness arrangements for dimensional inspection, NDT, and mechanical testing to meet strict project requirements.
Depending on your process route, we can supply parts as forged, heat treated, rough machined, semi-finished, or fully finish-machined.
Standard documentation includes EN 10204 3.1 certificates, heat-treatment records, dimensional reports, NDT reports, and a detailed marking list.
Forged parts offer superior grain flow and eliminate weld-joint vulnerabilities, providing significantly higher pressure confidence and structural reliability.
