OEM/ODM automotive-component enquiries include aluminum, steel, iron and stainless steel. Sand, gravity and investment casting are route choices to select around the material and drawing. Custom sizes, color and polishing can be defined for the required supplied component.
Explain the component’s place in the vehicle assembly
Provide the geometry and interfaces joining the part to adjacent components. Mark locating and attachment relationships with the applicable datums. State the service conditions and complete grade requirement so the proposal addresses the actual automotive part rather than a general material description.
Assign machining and finishing to the required result
Machining can be included where needed after casting. Identify finished dimensions and the stage at which they will be assessed. Show finishing allowances where the chosen approval stage requires them. Define polished areas, surface-treatment coverage and custom color where required, including masking or contact conditions at mating interfaces.
- Include quantity and the controlled component revision.
- State the required material condition and governing document.
- Identify cast and finished-surface acceptance boundaries.
- Describe the characteristics an approval part must demonstrate.
Set the automotive inspection brief
For the selected automotive casting, the stated 100% inspection should address the agreed dimensional, material and surface characteristics. Specify the checks and records required for approval. Request applicable ISO9001:2015 documentation and scope, then keep the approved part definition aligned with the production order’s material, route and final supplied state.
