Which kind of casting inerets you? ?They are all named castings, sharing features in common. But they are different.

Looking for aluminum or zinc alloy casting with thin wall? Then that's Die casting.

Looking for a stout ferrous casting with weight ranging from 0.1 kilo up to 1 ton? You may need Sand casting or Resin sand casting.

Looking for a delicate part of stainless steel without or saving most machining cost? I suggest investment casting (also named as lost wax technology), Silica sol or Sodium silicate.
