ToleranceCustomer's Drawing Request
Automotive-machinery sand castings can be requested in gray or ductile iron with customized sizes. For the gray-iron enquiry, specify the required ASTM A48 class. A ductile-iron component needs its own applicable grade and standard, with OEM/ODM work defined by the actual customer drawing.
Give the material requirement a clear scope
Identify the selected iron, governing document and required material condition for the component. Connect those requirements to its role in the machinery assembly. The drawing should distinguish material acceptance from dimensional limits used to judge mounting, mating and contact geometry.
Define fit through the controlled drawing
Mark the datums and dimensions that determine installation. Tolerances follow the customer’s drawing request, with the supplied condition and measurement stage made clear. If a reference part is provided, identify wear or damage and specify where the drawing governs the intended replacement shape.
- Provide quantity and the controlled revision.
- Mark the functional surfaces requiring acceptance.
- State the required material and surface records.
- Identify the sample-approval basis for the component.
Apply inspection to the automotive part
The stated 100% inspection under an ISO9001-system reference should address agreed characteristics and acceptance limits for this casting. Define the actual checks and records required to demonstrate them. Request the relevant certificate and supplier scope alongside those requirements, keeping approval connected to the chosen grade, geometry and delivered condition.
