Turbocharger Housing & High-Temperature Exhaust Castings
For turbocharger housings, turbine housings, exhaust adapters, and high-temperature exhaust connection parts, KTECH evaluates casting feasibility by temperature, thermal cycling, oxidation and corrosion exposure, thin-wall or complex internal geometry, material, machining, sealing faces, and quality-document requirements.
Project Review Focus
Confirm Structure, Material, Process and Quality Requirements
Geometry and wall thickness
Thin walls, wall transitions, flanges, complex inner geometry, and machining zones are checked against filling, shrinkage, porosity, leakage and distortion risk.
Material and documentation
CGI Si4Mo, high-nickel ductile iron, heat-resistant cast steel, stainless steel and other suitable directions can be reviewed with inspection records, material reports, dimensions and traceability requirements.

Quality and Delivery Review
Inspection, Documents and Shipment Requirements by Project
Defect risk review
Shrinkage, porosity, leakage, cold shut, deformation, and machining instability are reviewed during process planning.
Material and process
Material, mold, core, gating, feeding, controlled filling, and cooling approach are reviewed according to product geometry and service conditions. Counter-gravity or low-pressure sand casting can be evaluated where appropriate.
Inspection scope
Dimensional inspection, material report, hardness, air leakage, and traceability can be discussed according to project needs.

FAQ
What turbocharger housing casting projects are suitable for KTECH?+
Projects are suitable for review when temperature, structure, wall thickness, material, sample or drawing data, machining requirements, inspection scope, and realistic volume are clear.
Which materials can be reviewed for turbine housing and exhaust hot-end castings?+
Depending on service temperature, thermal cycling, oxidation, corrosion, geometry, machining and cost, project review may include CGI Si4Mo, high-nickel ductile iron, heat-resistant cast steel, stainless steel or other specified materials.
Can KTECH review current supplier quality issues?+
Yes. Photos, failure description, current material, inspection results, and samples help identify likely casting, machining or process risks.
