Custom Hollow Forging by Drawing is intended for cylindrical duty where the part must carry load through its wall section, bore, and end faces. For this category, buyers usually focus on wall-thickness consistency, bore straightness potential, heat-treatment response, and the availability of adequate stock for boring, facing, and sealing-area machining.
This option is used when the project requires a special bore, wall thickness, profile, or end geometry that does not fit a standard cylinder family. The forging is planned around the customer’s drawing so that material distribution supports both performance and downstream machining efficiency.

Supply Condition | As forged, heat treated, rough machined, semi-finished, or finish-machined according to project scope |
Machining Scope | OD/ID/faces, boring, counterbores, shoulders, sealing areas, and dimensional rough machining |
Inspection Options | UT, MT/PT where applicable, PMI, hardness, mechanical testing, dimensional inspection, and third-party witness |
Documentation | EN 10204 3.1, heat-treatment record, dimensional report, NDT report, marking list, and project-specific dossier |
Typical Applications | Drawing-based hollow parts; Special cylindrical components; Custom bores and wall sections; Non-standard heavy hollow forgings |
Commercial Note | Dimensions, heat treatment, machining allowance, and inspection scope can be arranged according to drawing and project specification. |
Wall-Section Reliability — Forged cylindrical sections offer better continuity and pressure confidence than many fabricated alternatives.
Bore and Face Machining Support — The supply condition can be matched to boring, honing, facing, and sealing-surface machining routes.
Load-Bearing Stability — These parts are intended for service where wall thickness and cylindrical integrity directly influence equipment safety.
Documentation and NDT Support — UT, mechanical testing, hardness checks, and EN 10204 3.1 documents can be supplied according to project scope.
Flexible Hollow Geometry — Custom bores, wall sections, shoulders, and end forms can be arranged to drawing for sleeves, shells, and hydraulic parts.
• Drawing-based hollow parts
• Special cylindrical components
• Custom bores and wall sections
• Non-standard heavy hollow forgings
Custom Hollow Forging by Drawing can be supplied as a forging blank, heat-treated forging, rough-machined forging, or semi-finished part according to the customer’s process route. Where the project requires closer dimensional control, additional OD/ID/facing, journal, bore, or drilling work can be incorporated before shipment.
For inspection-sensitive orders, Yongxinsheng can coordinate ultrasonic testing, MT/PT where applicable, PMI, hardness checks, mechanical testing, marking, EN 10204 3.1 documentation, and third-party witness arrangements. This makes the product suitable not only for general industrial procurement but also for project-based orders with stricter quality-document requirements.
