List four situations in which casting is the pre- ferred fabrication technique.

Question: List and briefly explain four situations where casting is the preferred fabrication technique. Answer: 1) Complex Shapes: Casting is suitable for components with intricate designs and complex shapes as molds can match the exact geometry. 2) Large Size and Heavy Components: Casting is efficient for creating large or heavy components since other techniques like machining or forging may be impractical. 3) Lower Production Costs: Casting minimizes waste material and labor costs, making it ideal for mass-produced items or large components. 4) High Melting Point Metals: Casting is suitable for metals with high melting points, such as stainless steel or titanium alloys, which are difficult to process using other techniques.
