Custom OEM aluminum automotive-spare-part enquiries offer selected die, gravity or sand-casting routes. The actual car component, alloy and required supplied condition should be identified through a controlled drawing. A precision request needs the dimensions and interface relationships that matter to the intended assembly.
Identify the spare part and fitment geometry
Provide the vehicle application and the component’s role, together with the mounting and mating surfaces that determine fit. Mark the geometry that must remain interchangeable with adjoining parts. If an existing spare is used as a reference, identify any wear or damage that should not define the replacement.
- State the complete aluminum grade and required condition.
- Provide the drawing revision and ordered quantity.
- Mark functional datums and controlled dimensions.
- Define the final surface and acceptance records.
Select the route for the drawing
The casting-method request should describe the actual component and production requirement. Distinguish the desired cast form from any additional work requested at finished interfaces. Establish which dimensions are checked at the supplied stage and how those measurements relate to the assembly.
Connect qualification and part approval
ISO9001 is the named qualification reference; identify the applicable document and supplier scope for the enquiry. Component acceptance should separately define the material, dimensional and surface records needed for the ordered spare. Where sample approval is requested, use the same drawing revision, grade and delivered condition that will govern subsequent supply.
