The investment casting is economical than other casting processes due to the following reasons
– Parts of great complexity and intricacy can be cast
– Close dimensional control and good surface finish
– Wax can usually be recovered for reuse
– Additional machining is not normally required ‑ this is a net shape process
A pattern made of wax is coated with a refractory material to make mold, after which wax is melted away prior to pouring molten metal described in bellow.
