Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. The term “lost-wax casting” can also refer to modern investment casting processes.A technique for making small, accurate castings in refractory alloys using a mold formed around a pattern of wax or similar material which is then removed by melting.
Investment casting is generally used for making complex-shaped components that require tighter tolerances, thinner walls and better surface finish than can be obtained with sand casting. The distinguishing feature of investment casting is the way the mould is made.
