| Preparation Time | Shorter, quick setup | Longer, requires packing and drying |
Plaster molds are ideal for detailed, small-scale casting with quick setup, while sand molds are better suited for larger, less detailed industrial castings. Both are used in foundries but serve different purposes based on project needs.
