Turbocharger turbine housings should be specified through their thermal duty, casting geometry and finished interfaces. This OEM/ODM enquiry includes grey iron, ductile iron or carbon steel with sand casting, CNC machining and customer-required surface treatment. Size and finish are customizable for the selected housing.
Match the housing drawing to the turbine assembly
Provide the complete component geometry and the interfaces required by the intended design. Identify the selected grade and operating conditions relevant to the turbine housing. The drawing should establish the dimensions that determine installation and service acceptance.
- Supply the housing drawing and controlled revision.
- Select the iron or carbon-steel grade.
- Describe thermal duty and turbine-interface requirements.
- Mark cast and CNC-finished acceptance dimensions.
Separate machining tolerance from as-cast acceptance
The machining reference is ±0.05 mm, while as-cast acceptance follows ISO 8062. Specify the applicable casting grade and controlled dimensions within the order. The CNC limits should apply to the identified finished interfaces rather than every surface of the sand casting.
Define finishing and inspection requirements
Surface treatment follows customer requirements. Describe the required result and any contact areas needing particular instructions. Strict 100% inspection is stated, with the characteristics and records to be agreed for the selected material and drawing.
Agree the supplied condition and order scope
The minimum order is 10 pieces, with bubble protection, carton and wooden-case packing named. Identify the quantity and required finished condition for the actual housing. Material, thermal duty and inspection acceptance should define the component without an assumed turbocharger fit or temperature rating.
