ToleranceCustomer's Drawing Request
ASTM A48 Class40 gray-iron sand castings are available for automotive-machinery OEM/ODM enquiries with DFM feedback. Ductile-iron components require an independently selected grade and acceptance definition. Customized size and tolerance should follow the actual component drawing and required supplied condition.
Focus DFM feedback on the working geometry
Identify wall sections, interfaces and inspection points requiring manufacturability discussion before production. Show the mounting and mating relationships governing the selected design. Keep accepted review decisions connected to the controlling drawing revision and actual material requirement.
Set casting and final-fit acceptance
Mark locating references and the dimensions controlling installation or operation. Distinguish regions accepted in the cast state from interfaces needing another final result. Agree measurement conditions for relationships assessed together during approval of the component against its equipment.
Scope inspection and supporting documents
The stated 100% inspection under an ISO9001 system needs actual checks and records for the chosen part. Identify material, dimensional and surface approval evidence. Request applicable system documentation with the relevant holder and activity scope, keeping material-class acceptance separate from any assembly-load requirement.
- State the automotive-machinery component’s quantity and revision.
- Identify final contact and appearance requirements at functional areas.
- Explain what an initial item must demonstrate after the selected DFM decisions.
- Retain approved grade and inspection-point changes within the part record.
Confirm further castings against the approved design and actual equipment duty.
