To comply with international maritime safety and classification society standards, this large-scale structural piece is verified with complete zero-defect assurance:
This guided tail fin is presented as a representative custom‑manufactured component for Shipbuilding; Marine engineering; Offshore platforms and vessels; Marine hardware and rudder‑related parts stated as customization examples Honyang Cast develops similar parts from customer drawings rather than offering a fixed catalog specification.
The manufacturing plan must connect the part's functional geometry—80 cm large‑scale profile; Long through‑hole structural design—with tooling, investment casting, machining and measurable inspection requirements. Final dimensions, interfaces and acceptance criteria are confirmed during drawing review.
PROJECT‑SPECIFIC SUPPLY
Material grade, dimensions, tolerance zones, machining allowance, surface condition, operating requirements and inspection records are confirmed after review of the customer’s 2D drawing, 3D model and project specification.
The parameter set is selected for this component’s function. Unknown values remain drawing‑controlled and must not be replaced with generic catalog data.
| Engineering Item | Reference / Custom Requirement | Verification Basis |
|---|---|---|
| Material grade | Grade 316L Stainless Steel (Marine Grade / Ultra‑Low Carbon) | Confirm governing standard and chemistry requirements. |
| Part weight | 31.12 kg | Confirm target weight and allowable variation when relevant. |
| Functional geometry | 80 cm large‑scale profile; Long through‑hole structural design | Identify drawing datums and critical‑to‑function features. |
| Casting / process reference | Complex reinforced multi‑layer shell process with extended cycle; Internal coring; ISO 8062 (GB/T6414) CT6 casting tolerance; Optional pickling and passivation | Confirm which steps apply to the quoted production route. |
| Dimensions and tolerances | To be confirmed from customer drawing. | Define casting tolerance separately from machined dimensions and GD&T. |
| Operating conditions | To be specified by customer. | Provide medium, load, temperature, pressure, speed or hygiene requirements as applicable. |
| Recommended additional fields | Overall profile; Section dimensions; Through‑hole diameter; Straightness; Datums; Machining allowance | Complete before publishing numeric claims or quoting production. |
| Structural Feature | Why It Matters | Manufacturing Response |
|---|---|---|
| 80 cm large‑scale profile | This feature influences fit, flow, load transfer, manufacturability or downstream assembly. | Control profile geometry, section transitions, hub or mounting interfaces, and balance‑related features according to the approved drawing. |
| Long through‑hole structural design | This feature influences fit, flow, load transfer, manufacturability or downstream assembly. | Control profile geometry, section transitions, hub or mounting interfaces, and balance‑related features according to the approved drawing. |

A project‑specific route is established after review of geometry, alloy, tolerance, volume and validation requirements.

PROCESS SCOPE
Investment casting and CNC machining are described as the core route. Heat treatment, coating, polishing, balancing, pressure testing, radiographic testing, PPAP or other special processes must be shown as project‑specific unless their scope is confirmed.
Honyang Cast supports drawing‑based development of guided tail fin and related investment cast components from manufacturability review through sample approval and repeat production.
| Application Requirement | Manufacturing Value |
|---|---|
| Drawing‑defined fit and function | A part‑specific DFM and inspection plan links casting geometry to the actual assembly and operating requirement. |
| Integrated complex geometry | Investment casting can consolidate features and reduce fabrication or excessive stock removal where the approved design supports it. |
| Repeatable critical interfaces | Controlled datums, machining and inspection support consistent assembly of functional surfaces and mating features. |
| Material and process traceability | Agreed material and inspection records provide evidence against the drawing and quality plan. |
| Product‑specific value | Maintain marine assembly alignment; Provide an integrated long internal passage; Reduce correction and machining risk |
