Applications for Custom Turbine Housing
What We Deliver for Your Custom Turbine Housing
HDC Manufacturing supports one-stop solutions for your custom turbine housing — from sample design to delivery.
Precision Casting
HDC offers mature precision casting for your complex turbine housing geometries, ensuring a dense, defect-free structure with no gas porosity or sand inclusions for long-term reliability under heat and pressure.
Post-Casting Machining
We CNC machine after casting to ensure custom turbine housing fits your bearing housing, flanges, and bolts properly. We strictly control coaxiality and positional accuracy for reliable, trouble-free assembly.
Surface Finishing
HDC’s in-house finishing delivers burr-free, contamination-free parts, while for enhanced performance and durability, we also offer AFM, precision grinding, tumble finishing, and HVOF thermal spraying.
Quality Control
We inspect every production stage to ensure consistent accuracy and zero defects for your turbine housings. Material testing, full-dimension, NDT, and leak testing reports are available upon your request.
Ready to bring your design to life?
Send us your drawings or concept, and we’ll turn them into precision-cast turbine housings ready for your application.
FAQs
What is your Minimum Order Quantity？
For existing molds, we have flexible MOQs. For fully custom volute designs requiring new tooling, a one-time mold fee applies, but we offer prototype sampling before moving to mass production.
How do I choose between SiMo Iron and Stainless Steel?
It depends on your EGT (Exhaust Gas Temp). SiMo Iron is cost-effective for daily drivers (up to 800°C), while our 1.4848 Cast Steel is essential for high-performance or racing setups exceeding 950°C to prevent housing cracks.
Do you offer different surface treatments for the housings?
Standard housing comes shot-blasted. For extreme heat, optional ceramic coating or high-temp paint reduces engine bay temps and improves looks.
What drawing formats do you accept?
We accept STEP, IGES, DXF, DWG, and PDF. If you only have a legacy 2D drawing without 3D data, we will model the part and return a 3D file for your approval before tooling production.
Do you provide after-sales support?
Yes. We stand behind our quality. We provide comprehensive after-sales service, including rapid response to any quality discrepancies, ongoing technical support, and full traceability with our material and inspection reports.
Can you arrange door-to-door delivery?
Yes. We offer hassle-free global logistics. Besides EXW, FOB, and CIF, we provide DDP (door-to-door) shipping services via international express, air freight, or sea freight, tailored to your project timeline.
