Short answer: Sand casting pours molten metal into a sand mould that is destroyed after each pour, making it the most versatile and economical route for low-to-medium volumes of large, complex metal parts. Green sand (clay-bonded, reusable) handles most jobs; no-bake resin sands give tighter tolerances; shell moulding yields thin, smooth walls; and investment casting takes over when fine detail is required. Understanding each binder helps designers choose the right process and avoid shrinkage, gas and inclusion defects.
