Alloy settles this comparison before anything else does. Die casting is commercially a non-ferrous process, so a carbon steel, stainless
Alloy and annual volume decide this, and for a ferrous part they decide it immediately: permanent mold casting is in
Lost foam casting gives you internal passages without cores and a casting without a parting line; green sand gives you
A ferrous investment casting still needs machining, but only on the minority of features whose print callouts exceed what any
Sand casting shapes metal as a liquid, poured into a sand mold and solidified in place; forging shapes it as
Choose sand casting for any part that is not a plain body of revolution, and centrifugal casting for tubes, sleeves,
Shell mold casting holds tighter tolerances, a smoother as-cast surface and thinner walls than green sand; green sand costs less
Coated sand casting and resin sand casting differ in when the resin meets the sand and how it cures. Coated
Investment casting holds tighter tolerances; sand casting tools cheaper and goes heavier. Five numbers from your own print decide which route fits a specific ferrous part.
Die casting is the better process for aluminum, zinc, and magnesium parts made in quantities that pay for a tool-steel
Green sand is the cheaper mold for small and medium ferrous castings made in volume; no-bake is the better process
