ToleranceCustomer's Drawing Request
This custom iron gearbox housing is intended for automotive machinery projects requiring a sand-cast component with drawing-defined sizes and tolerances. OEM and ODM service makes the housing requirements the starting point for the order, with the selected iron grade and assembly dimensions defining the part to be made.
Start with the gray iron requirement
ASTM A48 Class 30 gray iron identifies the material direction for this gearbox housing. Ductile iron and grey iron are also material choices within the offering, so specify the iron type and grade for the individual housing. Treat that selection as part of the component definition rather than assuming one iron type can automatically replace another.
Keep the housing interfaces explicit
Customized sizes allow the housing dimensions to follow the customer's drawing. Identify the dimensions that establish its relationship to the surrounding gearbox assembly, and distinguish them from dimensions with different acceptance needs. A housing is selected for the required assembly geometry; a generic size description cannot establish that relationship on its own.
Combine sand casting with drawing-based acceptance
Sand casting is the manufacturing process, and tolerance requirements follow the customer's drawing request. The specified 100% inspection should be connected to the dimensions and acceptance points agreed for that housing. This gives the casting and inspection discussion a common component reference without adding an unsupported numerical tolerance.
Evaluate the complete iron housing definition
For an automotive machinery project, consider material grade, housing geometry and drawing tolerances together when reviewing the proposed component. Keep those requirements consistent through the OEM/ODM discussion, and confirm the applicable ISO9001 documentation where procurement requires it. The decision should rest on the defined sand-cast housing and its accepted assembly requirements.
