Differential Pressure Flange

Technical Specifications & Capabilities

Advanced Quality Control for Intricate Internal Cavities

To ensure maximum structural integrity and blockages-free performance in high-precision fluid systems, we implement stringent final testing:

• Blind Groove & Cavity Inspection: 100% video-endoscope or visual check to guarantee that all porous blind grooves are perfectly clean, smooth, and free of metallic inclusions or ceramic dust.
  
• Dimensional Accuracy (CMM): Measured via Coordinate Measuring Machines to ensure absolute true position tolerances for all interlocking ports and blind holes.
  
• Non-Destructive Testing (NDT): Processed via Liquid Penetrant Testing (LPT) to detect and eliminate any surface or corner micro-cracks before shipping.
  
• Material Certification: Every batch is verified via Spectrometer for exact 316 chemical composition (with standard-compliant Chrome, Nickel, and Molybdenum levels).

Custom OEM / ODM Services

• Custom Fluid Circuitry: We custom-cast manifold blocks with varied internal routing, connection port sizes, and mounting hole layouts based on your 2D/3D drawings (STEP, IGES, DWG).
  
• Optional Post-Processing: We offer secondary high-precision CNC thread tapping (NPT, BSP), passivation for advanced chemical protection, or electropolishing upon request.
  
• Full Traceability: Material certificates and CMM inspection data sheets are provided standard with every delivery.

Custom Differential Pressure Flange Investment Casting

This differential pressure flange is presented as a representative custom‑manufactured component for Multi‑routing fluid control; Compact hydraulic/pneumatic circuits; Industrial pipeline fluid distribution networks 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—Complex structure with porous blind grooves; Multi‑routing internal fluid channels / compact manifold‑style geometry—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.

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 differential pressure flange 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.
