What is investment casting?

Method also called as precision investment casting. The method involves the use of expendable Pattern with a shell of refractory material surrounded to form a casting mould. Since the pattern made up of wax is melted out and gets destroyed. That is why the name-"Lost wax method".

Refractory slurry is formed around a wax pattern and allowed to harden. The pattern is then melted out when mould is baked. The molten metal is poured into the mould.

Once the casting has cooled sufficiently, the mold shell is chipped away from the casting. Next, the gates and runners are cut from the casting, and final postprocessing (sand blasting, machining) is done to finish the casting.
