ToleranceCustomer's Drawing Request
Industrial-machinery iron castings are offered through OEM/ODM sand-casting enquiries. Grey-iron references include GJL20, GJL25, GG20 and GG25, while ductile-iron components can be requested through a separately specified material requirement.
- Identify the machinery component and its drawing revision.
- Select the full iron designation and governing standard.
- Mark mounting, locating and functional-interface dimensions.
- Define the required supplied surface and material condition.
- State quantity and the acceptance records needed.
Keep the grade designation complete
Provide the precise material requirement used by the machinery design. The named grey-iron labels should be evaluated against their governing documents, with the actual grade agreed for the ordered component. A ductile-iron request needs its own complete designation rather than an assumed substitution for grey iron.
Use the drawing to define casting acceptance
Sizes are customized and tolerances follow the customer drawing. Identify the dimensions that establish how the part mounts and mates within the machinery. State the delivered condition needed at those interfaces so the quotation can address a defined casting rather than a broad material description.
Specify checks within the inspection scope
The service describes 100% inspection under an ISO9001 system. Define the dimensional, material and surface characteristics to be checked for the selected component, and request the applicable supplier qualification documents. Keeping those checks with the approved drawing and selected grade gives purchasing a consistent reference for accepting the supplied industrial casting.
