Turbine Casing

Technical Specifications & Advanced Engineering

Strict Automotive-Grade Quality Control & Testing

To ensure fail-safe performance and precise dimensional compliance under repetitive thermal shock cycles, every single batch undergoes elite validation:

• Internal Channel Clearance Inspection: 100% video-endoscope verified to ensure that the long special-shaped through-holes and narrow grooves are completely smooth, with absolutely zero water-soluble core residues or internal slag inclusions.
• Dimensional Accuracy & True Position (CMM): Measured via high-precision Coordinate Measuring Machines to check the geometric layout profile of the long part, preventing structural warping and guaranteeing flawless alignment with mating automotive housings.
• High-Temperature Metallurgy Control: Validated by Spectrometers to ensure exact 310 grade chemical composition (25% Chromium, 20% Nickel) for maximum oxidation resistance.
• Non-Destructive Testing (NDT): Processed via Liquid Penetrant Testing (LPT) to guarantee that the critical narrow grooves and thin-wall radiuses are completely free of surface or thermal micro-cracks.

Custom Turbine Casing Investment Casting

This turbine casing is presented as a representative custom‑manufactured component for Automotive field; Turbocharging; EGR; Exhaust‑system components 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—Long special‑shaped through‑hole; Narrow grooves—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.

Key Technical Parameters & Custom Specifications

The parameter set is selected for this component’s function. Unknown values remain drawing‑controlled and must not be replaced with generic catalog data.

Part Design & Structural Features

Manufacturing Process & Machining Plan

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

1. Drawing and DFM review — identify functional interfaces, wall transitions, draft, machining allowance, datums and inspection access.
2. Tooling and pattern planning — develop the wax tooling, core strategy and pattern assembly method required by the approved geometry.
3. Investment casting — control wax pattern, ceramic shell, melting, pouring and solidification for the selected alloy and part geometry.
4. Shell removal and finishing — remove gating, clean the casting and prepare critical areas for inspection or machining.
5. CNC machining where required — machine sealing faces, bores, threads, holes or mounting interfaces defined by the drawing.
6. Final inspection and records — verify agreed characteristics and compile project‑required material, dimensional or NDT records.

• Water‑soluble core molding for the intricate inner hole — applicability and scope to be confirmed for this project.
• Multi‑gate gating‑system molding — applicability and scope to be confirmed for this project.
• Optional shot blasting, sandblasting or pickling is described — applicability and scope to be confirmed for this project.

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.

Custom Development Capability

Honyang Cast supports drawing‑based development of turbine casing and related investment cast components from manufacturability review through sample approval and repeat production.

1. RFQ input — submit 2D drawing, STEP/IGES model, material, annual volume, operating conditions and critical characteristics.
2. DFM review — align casting feasibility, core or gating strategy, machining allowance, datum scheme and inspection approach.
3. Tooling and sample — develop tooling, produce initial samples and inspect agreed characteristics.
4. Customer approval — review samples, dimensions and records under the agreed approval process.
5. Production delivery — supply as‑cast, machined, finished or assembly‑ready parts according to the confirmed scope.
