Customer Benefits / Value |
Material |
HTANi15Cu6Cr2 (Ni-Resist High-Nickel Austenitic Iron) |
Formulated with 15% Ni, 6% Cu, and 2% Cr to deliver exceptional defense against sour crude ( H₂S), saltwater, and abrasive sand erosion. |
Application Scenario |
Oil Extraction / Downhole Submersible Pumps (ESP) / Oilfield Fluid Handling |
Purpose-built to endure continuous fluid shear stress and chemical corrosion in ultra-deep oil well extraction environments. |
Unit Weight |
0.525 kg |
Lightweight, geometry-optimized profile engineered for high-efficiency dynamic rotation balances. |
Pattern Craft |
Precision Separate Splicing of Wax Molds |
Overcomes complex closed-vane undercut geometries; proprietary assembly fixtures ensure perfectly balanced internal fluid paths. |
Molding & Pouring |
Complex Shell-Making & Optimized Low-Temperature Casting |
Advanced premium slurry coating provides excellent gas permeability, while controlled low-temperature pouring yields a highly dense, fine-grain matrix. |
Machining State |
Precision CNC Machined Outer Surface Provided |
Delivered with pristine outer dimension turning to ensure immediate, tight concentric assembly with downhole pump housings. |
Casting Tolerance |
ISO 8062 (GB/T6414) CT6 Grade |
Elite near-net-shape accuracy for the as-cast segments, significantly decreasing secondary machining cycles. |
To prevent costly downhole pump failures and ensure long-term extraction uptime, our inspection team implements uncompromising quality protocols:
This impeller is presented as a representative custom‑manufactured component for Oil extraction; Downhole electric submersible pumps; Oilfield fluid handling; Ultra‑deep oil wells 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—Closed‑vane undercut geometry; Spliced multi‑vane internal flow paths; Precision‑machined outer surface—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.

| Structural Feature | Why It Matters | Manufacturing Response |
|---|---|---|
| Closed‑vane undercut geometry | 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. |
| Spliced multi‑vane internal flow paths | 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. |
| Precision‑machined outer surface | 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 impeller 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 | Transfer oilfield fluids; Support efficient pump‑stage rotation; Reduce post‑cast outer‑diameter machining |
