Cast Iron Turbocharger Housing Components | Heat-Resistant & Precision-Sealed for Power Systems
With over 10 years of experience as an integrated manufacturing and foreign trade enterprise, we specialize in producing high-quality cast iron turbocharger housing components. As a core part of turbocharger systems, our components are engineered to deliver exceptional heat resistance (up to 650℃), high-pressure tolerance, and precision sealing—critical for ensuring efficient power boosting and stable operation of diesel/gasoline engines in automotive, commercial vehicle, and industrial power generation fields. Serving global B2B clients including turbocharger manufacturers, automotive engine suppliers, and commercial vehicle assemblers, we provide consistent quality backed by international certifications, professional technical support, and seamless global logistics solutions that meet Western market standards.
Why Cast Iron for Turbocharger Housing Components?
Turbocharger housing components operate in extreme environments with high temperature, high pressure, and rapid temperature changes—cast iron emerges as the optimal material due to its unique properties:
• Excellent high-temperature stability: Maintains structural integrity at 400-650℃, resisting deformation under long-term high-temperature engine exhaust gas impact
• Superior pressure resistance: Withstands internal pressure up to 2.5MPa, ensuring safe operation of turbocharger compression systems
• Precise sealing compatibility: Enables tight fitting with turbine shafts and bearing housings, preventing exhaust gas leakage and ensuring boosting efficiency
• Good castability: Easily forms complex internal flow channels (exhaust gas inlets/outlets, scroll passages) required for turbocharger aerodynamic performance
• Cost-effectiveness: Balances high-temperature performance with competitive pricing, suitable for mass production of turbocharger systems
We exclusively adopt high-quality heat-resistant cast iron grades (gray cast iron HT300, ductile iron QT600-3) that meet ISO 185 and ASTM A48 standards, with full Material Test Certificates (MTC) provided for each batch to ensure traceability and material reliability.
Core Production Process & Supplementary Technologies
Our production process is tailored for the high-precision and high-temperature requirements of turbocharger housing components, centered on precision casting and supplemented by advanced machining technologies. The visualized workflow is as follows:
1. Certified Heat-Resistant Cast Iron Sourcing: Raw cast iron is sourced from ISO-certified suppliers. We conduct strict chemical composition analysis (focus on chromium, molybdenum content) and high-temperature hardness testing to ensure heat resistance.
2. Precision Sand Casting & Investment Casting: Adopt resin sand casting for large-batch standard housings (ensuring mold stability and cost efficiency) and investment casting for complex-shaped high-precision housings (achieving fine surface quality). Optimize mold pouring system to avoid shrinkage and porosity.
3. High-Temperature Heat Treatment: Implement multi-stage heat treatment (normalization + tempering + aging) to enhance material high-temperature toughness (HB 220-280) and reduce internal stress, preventing deformation under extreme temperature changes.
4. Precision CNC Machining: Equipped with 20+ sets of CNC lathes, milling machines, and boring machines to process key surfaces (flange mating surfaces, shaft holes, sealing grooves) with high precision. Use diamond tools for machining hard cast iron surfaces to ensure dimensional accuracy.
5. Specialized Surface Treatment: Custom processes including high-temperature anti-corrosion coating (resisting 700℃+), phosphating, and chrome plating to enhance high-temperature corrosion resistance and wear resistance. All treatments comply with RoHS and REACH standards.
6. Strict Quality Testing: 100% dimensional inspection via Coordinate Measuring Machine (CMM); X-ray flaw detection for internal casting defects; high-temperature sealing testing (650℃, 2.5MPa, no leakage for 30 minutes); and material high-temperature performance verification. Only qualified products are shipped.
7. Secure Packaging & Global Shipping: High-temperature resistant film + shockproof foam + wooden crate packaging to protect components during transportation. Partner with DHL, FedEx, and Maersk to provide delivery to 150+ countries, with complete customs clearance documents (commercial invoice, certificate of origin, MTC).
Supplementary processes such as welding (for component assembly), dynamic balance testing (for rotating-related components), and custom drilling are available to meet specific requirements of turbocharger manufacturers.
