Custom Turbine Housing Castings

Source turbocharger turbine housings and industrial turbine casings made to your drawing, 3D model, or existing part. YTD coordinates casting, CNC machining, finishing, and inspection in one project, so you receive the housing at the stage your production team needs.

Turbocharger Turbine Housing Designs

The housing has to match the turbocharger around it. Use these familiar design features to describe what you need; the complete geometry still follows your drawing or sample.

Turbine Housings Made to Your Drawing

A turbine housing is usually tied to a particular wheel, manifold, shaft system, or machine. Even familiar designs change when the flow path, flange, material, mounting space, or service conditions change.

Send the finished housing you need, rather than trying to prepare a casting specification. We review the internal passages, wall transitions, machining stock, interfaces, material, and inspection requirements together, then build the manufacturing proposal around the complete part.

A current drawing is the best starting point, but it is not the only one. A 3D model, an older drawing, clear photographs, or a physical housing can also begin the conversation.

Materials for Turbine Housings

Temperature, exhaust or process chemistry, thermal cycling, strength, and expected service life all influence the metal. If the grade is already specified, send it with the drawing. If it is still open, the operating conditions give us a useful place to start.

SiMo & Heat-Resistant Cast Iron

Turbocharger hot-side housings face repeated heating and cooling in the exhaust stream. SiMo and other heat-resistant cast irons are common starting points when thermal stability, oxidation resistance, durability, and production cost must be balanced.

Stainless & Heat-Resistant Steel

Corrosive gases, elevated temperatures, or higher mechanical demands may lead to stainless or heat-resistant cast steel. Different grade families allow the metal to be matched more closely to the environment the housing will actually see.

High-Temperature Alloys

Nickel-, cobalt-, and iron-base alloys become relevant when ordinary steels no longer provide the required hot strength, oxidation resistance, or stability. YTD combines high-temperature alloy casting with the heat treatment, machining, and inspection specified for the part.

Carbon & Alloy Steel

Industrial turbine casings and support housings often put greater emphasis on structural strength, toughness, section size, and heat-treatment requirements. Carbon and alloy steel grades offer a broad range for these designs.

Investment and Sand Casting for Turbine Housings

Compact housings with curved volutes, detailed bosses, and closely spaced features may suit silica-sol investment casting. It forms much of the shape in the casting and leaves the wheel bore, flanges, registers, and other functional interfaces for controlled machining.

Sand casting opens the route to larger industrial turbine casings and heavier housing designs. It also gives the project more freedom to plan large sections, cores, machining allowance, and handling around the scale of the part.

You do not need to choose between the two before contacting us. Geometry, material, size, quantity, final machining, and inspection all shape the decision. YTD reviews the finished part first and coordinates the selected route through delivery.

Turbine Housing Delivery Options

Choose how much work should be completed before the housing reaches your plant. The same project can cover the casting alone or continue through machining, finishing, inspection, and packing.

Raw Turbine Housing Castings

Receive a cleaned housing casting with machining allowance left on the wheel opening, flanges, split faces, bearing locations, or other areas your team plans to finish.

Machined Turbine Housings

Wheel bores, bearing-housing registers, inlet and outlet flanges, bolt holes, split lines, seal locations, and mounting faces can be machined to the finished drawing.

Finished & Inspected Housings

Add the required heat treatment, surface finishing, dimensional checks, material tests, nondestructive testing, marking, and export packing before shipment.

From Turbine Housing Drawing to Production

Your project moves forward through a small number of clear decisions, with a real sample checked before the production batch is released.

Review the Housing

We begin with the design, material, service conditions, quantity, critical interfaces, and the stage at which you want to receive the part.

Plan Casting & Tooling

The housing geometry is translated into a casting and tooling proposal that also accounts for cores, machining allowance, finishing, and inspection.

Check the First Housing

The first casting gives your team something real to measure, inspect, and trial in the assembly. Agreed corrections are completed before the batch moves ahead.

Produce Repeat Orders

After approval, production follows the agreed drawing, specifications, inspection plan, and accepted sample. Those records provide the reference for later orders.

Turbine Housing Features and Inspection

A housing can look complete before its most important surfaces are finished. On a turbocharger housing, attention often centers on the volute, wheel clearance, bearing-housing register, inlet and outlet connections, bolt pattern, and wastegate features. Industrial turbine casings bring a different set of priorities, including split lines, flow passages, bearing and seal locations, and large mounting interfaces.

YTD plans the casting and machining around the finished drawing. Your inspection scope can include:

  • Material composition, hardness, and tensile testing
  • Dimensional inspection and CMM reports for specified interfaces
  • Fluorescent penetrant and X-ray inspection when required

Acceptance requirements are agreed before production, giving both teams the same basis for reviewing the first housing and the parts that follow.

Request a Turbine Housing Quote

Start with what you know and what you already have. We will identify any missing details during the review and prepare the quote around the housing and delivery stage you need.

Drawing, Model or Sample

Upload the latest drawing or 3D model. An older drawing, clear photographs, or an available physical housing can also begin a replacement-part review.
Send Your Design

Design & Service Conditions

Share the details you have. For a turbo housing, that may include the scroll, A/R, flanges, wheel size, wastegate, and exhaust temperature. For an industrial casing, the casing type, material, temperature, internal interfaces, and assembly drawing are useful.

Turbine Housing Casting FAQs

Practical answers about starting a custom turbine housing project with YTD.

Yes. YTD works on compact turbocharger turbine housings as well as larger steam and gas turbine casings, bearing housings, seal housings, and support housings. Projects can range from several kilograms to more than 100 kg.

No. Send the finished housing design and the requirements you already know. We will review its geometry, material, size, quantity, machining, and inspection needs before proposing a manufacturing route.

An older drawing, 3D model, clear photographs, or a physical housing can start the review. We will establish what additional dimensions, material information, or acceptance criteria are needed before tooling and samples begin.

Options include carbon and alloy steels, stainless and heat-resistant steels, nickel-, cobalt-, and iron-base high-temperature alloys, plus SiMo and other heat-resistant cast irons for turbocharger housings. The final grade follows the drawing and service conditions.

Yes. The project can include CNC machining, heat treatment, surface finishing, material testing, dimensional inspection, CMM reports, penetrant testing, X-ray inspection, marking, and packing as required.

A drawing, 3D model, or sample is the best starting point. Material, quantity, service temperature, critical interfaces, delivery condition, and inspection requirements help us define the scope and prepare the quotation.
