Cast Iron Turbine Housing Shell Molding For Machinery, Trucks, Special Equipment & Vehicles

Technical Advantages

Full In-House Manufacturing

Pattern shop, shell molding & resin sand casting lines, CNC machining, heat treatment, and inspection lab — all centralized under one roof. No outsourcing. From base iron melting to finished and coated part, we maintain full control over lead time, quality consistency, and batch traceability.

Design for Manufacturability (DFM) Support

Before pattern production begins, we provide a detailed DFM report covering solidification behavior, graphite morphology control, gating & riser design, core assembly strategy, and machining allowance optimization. For turbocharger turbine housings like this 3.8 kg QT600 component, we focus on volute wall thickness uniformity to ensure even thermal expansion, riser placement at flange intersections to eliminate shrinkage, and core stability for the complex internal volute passage to maintain gas flow accuracy.

 Expertise in Complex Iron Castings

We specialize in geometrically demanding parts with complex internal cavities and multi-core assemblies — such as turbocharger turbine housings, exhaust manifolds, gearboxes, pump housings, and cylinder heads. Our shell molding process delivers superior surface finish on volute passages and sealing faces, excellent dimensional repeatability for high-volume production, and precise core integrity for intricate internal gas flow channels. We pour a full range of grades — grey iron (HT150–HT350), ductile iron (QT400-18 to QT700-2) — with in-house heat treatment to tailor hardness, strength, and thermal fatigue resistance to your specification.

Service Advantages

 Dedicated Cross-Functional Support

A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage and a single point of contact for all technical and commercial matters.

 Fast Response & Transparent Communication

Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project. For turbocharger components, first-article inspection reports including dimensional layout and material certification are provided before batch production begins.

 After-Sales Support

Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support. Flexible MOQ with pilot order options available for new turbine housing projects.
