ToleranceCustomer's Drawing Request
Wholesale OEM and ODM enquiries cover ASTM A48 Class 30 gray iron sand cast parts for automotive machinery. Dimensions are customized and tolerances follow customer drawings. A ductile iron alternative must have its own complete material specification, distinct from the Class 30 gray iron requirement.
Build a clear component order schedule
Identify the drawing revision, selected material and required quantity for each part. Describe the machinery function and the interfaces that determine installation. Where several castings are requested together, keep their grades and dimensional acceptance requirements separate so each ordered component remains traceable.
Set applicable material and code requirements
Connect the selected gray iron requirement to its governing material specification. Identify the actual ASME code, document and component scope needed for the order. Establish the relevant ISO 9001 certification document and scope separately from material-grade or application-specific acceptance requirements.
Agree how finished parts will be accepted
Quality control is stated as 100% inspection under an ISO 9001 system. Define the checks and records required for the actual castings. Mark critical dimensional relationships and the datums used to evaluate fit. Include any additional machining or surface requirements for agreement in the quotation.
State the initial part-approval stages and the documents needed before repeat production. Explain operating conditions relevant to evaluating the selected material and geometry. Keep approved changes linked to the same drawing, iron specification and supplied condition. This gives wholesale enquiries a consistent basis for specifying the automotive components and their acceptance records.
