In casting, the suitability of parts is independent of the desired quantity.

• A. True
• B. False
• C. Not sure
• D. Depends

Answer: (A)

In casting, whether a part can be produced is determined by its geometry and material, not how many you need. Design-for-castability factors—draft angles, wall thickness variation, undercuts, fillets, tolerances, surface finish, and features like cores or internal cavities—govern if the part is feasible to cast. These considerations are about physical feasibility of a single part, and they don’t depend on production quantity. Quantity mainly drives cost, tooling, and process selection (for example, whether you use a simple sand mold or an expensive investment casting setup), but it doesn’t change whether the part could be cast in principle. So the part’s suitability for casting is independent of the desired quantity.
